Storage and Maintenance

Why is maintenance important?
Two way radios are versatile and robust devices, and, when looked after properly, will serve you well for years. Even the most rugged piece of equipment will deteriorate quickly if it isn’t properly looked after. Waterproof seals can perish, switches can seize or fail, batteries can fail, and grime and dirt can block speaker and microphone openings.

A few simple steps can greatly enhance the lifespan of your radio and keep it working at its full potential throughout its lifetime. Basic maintenance and care are all that is needed, so you don’t have to be comfortable with electronics or be handy with a screwdriver. Just a little diligence and some common sense are all!

1. Inspect Regularly
How often you need to apply this care and attention is down to many factors, some of the common ones are:

Type of usage – If your two way radios are used regularly in dirty, wet, or other harsh conditions, then it is best to inspect them daily.
Frequency of use – The more frequently the radios are used, the more frequently they should be inspected.
Age – Just like us humans, two way radios can get a bit wobbly as they age if not treated properly! In particular, look at the battery life in older two way radios and consider changing them if necessary.
If the batteries are removable, then remove them and look for signs of corrosion and leakage on the batteries and the terminals of the radio. As well as the batteries, the inspection should look for visible signs of damage, grime and dirt build-up, and whether the switches still feel as they should when operated.

2. Store properly
The correct storage is critical if you want to prolong the life of your two way radio. Much of this common sense, don’t store where it is exposed to direct sunlight, or in extremes of temperatures etc. But there is a good chance that your radio will be spending a lot of its life in storage, so it is a critical factor.

Cleaning – Cleaning your two way radio before storage is especially important if it is to be stored for a long period. This stops moulds and fungus from growing and also prevents dirt from hardening over time and potentially damaging the radio. Even if your two way radio looks completely clean, it is good practice to wipe them with a dry or slightly damp cloth before storage.
Important – Always check the our cleaning and maintenance instructions first.

Batteries – Another factor to be considered for long term storage is the batteries. If they are removable, then do so before you store them. Also, for rechargeable batteries, it is best not to store them with a full charge. Fully charged batteries are “stressed,” and this can severely degrade their useful life.
Dry – Always ensure that your radios are completely dry before storing them. This can prevent both water ingress and can also prevent moulds from growing when in longer-term storage.

3. Clean vents and grills regularly
Speaker and microphone grills, where present, should be cleaned regularly to keep the clarity of sound crystal-clear at both ends of the conversation.

Equally important are any ventilation vents on the radio. Electronic circuitry runs warm, and these vents are essential to dissipate that heat. Overheating is one of the major killers of electronics and making sure these vents are always clean will help keep both you and your radios chilled.

The easiest way to do this is by using a little antibacterial or specialized cleaner onto a microfibre cloth or cotton bud and gently cleaning the grills. Once again, it is essential to check the our instructions first to make sure there are no specific instructions for your device.

Radio Care
●Do not pierce or scrape the radio with any edged instruments or hard objects.
●Keep the radio far away from substances that can corrode the electronic circuit.
●Do not hold the radio by its antenna or headset cable directly.
●Attach the accessory jack cover when the radio is not in use.

Radio Cleaning
●Clean up the dust and fine particles on the radio surface and charging piece with a clean and dry lint-free cloth or a brush regularly.
●Use neutral cleanser and a non-woven fabric to clean the keys, control knobs and front case after long-time use. Do not use chemical preparations such as stain removers, alcohol, sprays or oil preparations, so as to avoid surface case damage. Make sure the radio is completely dry before use.

Caution: Power off the radio and remove the battery before cleaning.

4. Protect as much as possible when in use
Even the most robust and waterproof two way radio should be protected from the elements where possible. This doesn’t mean not using it in the rain. All it means is that if there is an option that avoids the rain, then it is the prudent choice.

Over the short term, this won’t make much of a difference, but you can expect a two way radio to last for years, and throughout a long lifetime, these little steps can make a big difference.

Both water and dust are known for their downright persistence, and reducing the exposure to them, wherever possible, is a great way to keep your leisure or business two way radio radios in pristine condition.

5. Battery maintenance
We touched on battery care a little earlier, but battery care extends, and maintenance is important at all times, not just when storing your two way radio.

Whenever possible, don’t leave them attached to a charger after they are fully charged.
Always use the our charger or a charger that they recommend as suitable.
It is better to not fully deplete your battery before charging, however, at the same time, it is also not good practice to charge them every time the battery drops to 90%. A good aim is to look at around 30% as the optimum time to charge your battery.
Well looked after batteries can last for up to 18 months and still be capable of holding plenty of charge. However, we will recommend that batteries be replaced after this period, regardless of their performance.

For specific battery guidance for your model, then it is best to check the manual or our website.

Conclusion
A well looked after two way radio should serve you well for years, and as you can see from the above steps, the maintenance needed is minimal. But this little bit of maintenance can add years of quality usage from any two-way radio.

If you have any questions or concerns about maintaining your radio, we are also here to help make sure you get the very best from your two way radio.

F.A.Q.

●Where are AAHHi radios manufactured?
AAHHi radios are manufactured at our production plant in Quanzhou China. All AAHHi radios are put through rigorous in-house quality tests and environmental tests as they come off the line and before shipping. Our radios marked "Made in China". Controlling production at our own facilities guarantees precision and build quality.

●Buying our repair spares
If you are in the position where you need your radio fixed, there are a number of avenues that you can take. You can choose to have your radio repaired by a local dealer or even send it back to our service department safe in the knowledge that a professional will be carrying out the work.

Alternatively, if you have the skill and knowledge to fix your own radio yourself, we have a dedicated spares department with a huge inventory of repair spares for all models across all of our markets. If you ever need our help in this matter, email us at info@aahhi.com.
　

●Should we purchase UHF, VHF, or Digital?
UHF radios will perform well both indoors and outdoors. VHF radios are best for outdoor use. Digital radios perform best indoors.

●What’s the difference between VHF and UHF radios?
The difference is frequency penetration. Ultra High Frequency (UHF) radio waves penetrate steel, concrete and brick walls, or rugged terrain, making them ideal for situations that need indoor – to – outdoor communications, or communications between floors of a building. Very High Frequency (VHF) radio waves travel best where there are no obstructions, making them the right choice for outdoor communication in areas with open land, rolling hills or thick forests.

●How many watts do I need?
Wattage determines the strength of your radio signal with UHF & VHF radios. The larger the jobsite, the more watts you should purchase. Please refer to the wattage and range of each radio before purchasing.

●How many channels do I need?
Channels are used to segregate work teams within the jobsite. Each work group can have their own channel to minimize disruptions in other departments. Digital radios provide the added benefit of allowing each worker to have an individual channel for single person-to-person communication as well as a channel for their work group.

●How far will the radios communicate?
The radios are designed to provide complete coverage of your jobsite. The radios are not designed to provide communication from the jobsite but may work a mile or so away from the site. If you require more coverage a Repeater may be an option.

●What is the warranty on the radios?
All our AAHHi Radios come with a replacement warranty for one year from the date of shipment we ship and accessories only for 6 monthes.

●How many radios can be used at one time?
You may use as many as you like. We recommend using an additional channel for every 10 employees.

●Will our two way radios communicate with other brands of radios?
Yes, provided the other radios are programmed to the same frequency and codes. Please contact your dealer for assistance.

●What does " 5 : 5 : 90 " Mean on a Battery Rating?
This is an industry standard that is called a 5, 5, 90 Duty cycle. This means that a new, fully charged battery will generally last XX hours if:
• Transmit time at 5%: You transmit 5% of the time
• Receiving time at 5%: Your speaker is active (you are receiving) 5% of the time
• Standby time at 90%: Your radio sits idle (no TX or RX) 90% of the time

●What should I do, if the radio is dropped into water?
Take the radio out of water as quick as possible and remove the battery as quick as possible. Swing the water out of radio and put the radio at the place where the ventilation is good so that the radio be dried quickly. At last but not least, return the radio to our authorized dealer for maintenance as early as possible.

●I can not turn on the radio and even it is turned on, it often shuts off automatically. Why?
Please check the battery contacts on the radio. If it is broken or twisted, please return the radio to our authorized dealer for maintenance.

●There is no display or something strange displayed on my LCD? Why?
This happens because of the poor connection between the LCD and PCB. The possible cause of this is that the radio was dropped and not used properly. Please return the radio to our authorized dealer for maintenance.

●Why can I hear the voices clearly from other group, sometimes, my voice is intermittent. Why?
Please check whether the MIC is blocked by something. If so, Please return the radio to our authorized dealer for maintenance.

●The voice received is intermittent with rather big noises.
Usually, when the radios are at the edge of the coverage area or in some places where the radio signals are interrupted or blocked, this symptom will happen. Please kindly verify the above. If necessary, please return the radio to our authorized dealer for maintenance.

●How to judge the performance of different model radio?
Based on the different parameter: band range, Tx power, Rx sensitivity, and other data.

●Does the radio have radiation? How to use the radio safely while it works?
Yes. So, when use a radio, hold the radio in a vertical position? And keep about 2-5 centimeters distance with the radio.

●How to use the earphone correctly?
(1)Do not draw the earphone cable hardly.
(2)Don not stick in or pull out the earphone from the jack frequently.

●How long is the communicate distance?
The communicate distance would be disturbed by following factors:
(1)Environment: If you use it around high buildings and large mansions, the communication range is smaller.
(2)Weather: If you use the radio in rainy day, the radio performance maybe poor.
(3)Power: If the power of the radio is very low, you have a poor communicate distance.

●Is long antenna better than short antenna?
No. Short antenna has convenient-design, and easy to carry. Long antenna covers wider communication range. So the choice all depends on the environment and personal favorite.

●How to make my radio talk to others?
Firstly, make sure to use the same technology radios (both of two radios are the same analogy or digital radios), secondly, set the two radios in the same frequency, thirdly, set the same CDCSS/CTCSS/Signaling & Encryption, and at last they can talk each other.

●Why the programming software updates so quick, and incompatible?
To perfect the software, the updating is necessary, and the new one has good compatibility. If you want the latest edition, we could supply it for you.

●What kind of batteries you can offer, what's the difference among them?
There are mult-kinds of batteries we can offer, i.e. aluminum shell Li-ion battery, 18650 Li-ion battery, Li-poly battery ect.

●Radio to Radio Clone Method
When a lot of radios need to be programmed, the fast and secure way to do this is to do radio-to-radio clone. AAHHi radios can support wired clone and wireless clone, depending on the radio functionalities. Please contact our authorized dealer to get the detailed clone procedures for your radio.

●Why Couldn't I communicate with other group members?
First, please verify that the channel frequency and the CTCSS you are using are the same as those of your group members. If the channel frequency and the CTCSS are the same, please verify that your group members are within the radio coverage.

●Why is the radio communication range shorter than before and the sensitivity becomes poorer?
Please check the antenna and make sure it is a good one. Also please check the antenna socket is not damaged or loosened. If so, please return the radio to our authorized dealer for maintenance.

●After a period of time, my radio works well, but no sound from my earpiece.
The socket inside the radio has been damaged. Please return the radio to our authorized dealer for maintenance.

●After the radio is programmed, there are noises from radio like "dudududu" Why?
This happens because the radio is wrongly programmed. This noise is an indication that the channel frequency programmed is out of the frequency range supported by this radio. Please check your setting or turn to a professional engineer for help.

●My radio can not scan channels? Why?
This happens because when the radio is programmed, the channel is not included into the scan list. Or the whole channel scan function is not turned on for the radio. Please turn to a professional engineer to troubleshoot this problem.

●What is the battery life cycle?
Please replace your old battery with a new one when the battery life cycle is over, so that you can get the best performance from your radios. For a Ni-MH battery, it is designed to 500 standard recharge & discharge cycles; for a Li-ion, 1000 standard cycles.

●Why can I hear the voice from other groups?
Please change your CTCSS for the channel. At the same time, you also need to the CTCSS for all the radios in your group. If you don't like this, you may apply another channel frequency.

●Why I can't hear from the earphone when the indicator flash green?
There may be poor contact between earphone and earphone jack. Please plug out the earphone and plug in again.

●Why the radio transmit only?
Check if PTT is blocked with something. There should be slight “dadada” at the pressing of PTT.

●I can not turn on the radio and even it is turned on, it often shuts off automatically, Why?
Please check if the battery contact is out of shape. Or make sure the switch is not loosened.

●Why my voice received is low?
Please check if the MIC is blocked by something. And make sure that the volume is turned high.

●What should I do, if the radio is dropped into water?
Take the radio out of water and remove the battery as quick as possible. Swing the water out of radio and put the radio at a dry and ventilated place. Return the radio to our authorized dealer for maintenance as early as possible.

●Why Couldn't I communicate with other group members?
First, please verify that the frequency point and the CTCSS you are using are the same as those of your group members. If the channel frequency and the CTCSS are the same, please verify that your group members are within radio communication range.

●Why can I hear the voice from other groups?
Please change your CTCSS for the channel. At the same time, you also need to change the CTCSS for all the radios in your group. If you don't like this, you may switch to another channel.

●After a period of time, my radio works well, but no sound from my earpiece.
The socket inside the radio has been damaged. Please return the radio to our authorized dealer for maintenance.

●Why is the radio communication range shorter than before and the sensitivity becomes poorer?
Please check the antenna and make sure it is a good one. Also please check the antenna socket is not damaged or loosened. If so, please return the radio to our authorized dealer for maintenance.

●Solutions to FAQs when trying the radio
1.Frequency Interference: Voices from other group or other broadcasting stations are heard on the channel. Three methods are available:

① Change Channel

② Set CDCSS/CTCSS or DTMF code

③ Lower the squelch level.
2.Short Distance: If there is difference between required communication distance and practical distance, the communication can be realized through adjustment of radio RF power or squelch level. Or, a repeater is suggested added to improve the communication.
3.Intermittent Voice: Intermittent voice is often heard in critical distance during radio communication. Under such condition, please adjust squelch level or cancel CDCSS/CTCSS code to improve it.
4.Squeaking: It's normal that squeaking may be heard on the channel when two radios is several meters near or closer. Users can adjust the volume to improve it.

●Is a license required?
On certain models. Please visit the website of your local communications management agency in your country or call for consultation for more information.

●Are your radios narrowband compliant?
Yes, all of our radios meet the FCC regulation of being 12.5 kHz or equivalent.

●Why do I need to license my radios with the FCC?
The Federal Communications Commission (FCC) is not licensing your radios – it’s licensing the radio frequency used by your radios. The airwaves are considered public property and the FCC is mandated to regulate the use of those public airwaves. Radio and television stations are required to be licensed for use of broadcast airwaves, and so are all radio operators, from business class to citizen band (CB) to ham radio operators.

●Are chargers compatible from one radio series to another?
No. Due to different battery chemistries, sizes, and charge times each radio requires its own charging system.
