Dual Band |
|
 |
Dual Display |
| |
Radios with Dual Band
capability can transmit and receive on both UHF and VHF
radio bands. |
|
|
The LCD screen allows users
to view the current information of the two frequency
bands or other settings, providing a larger amount of
visual information. |
|
 |
Dual Watch |
|
 |
Dual Receive |
| |
Allows user to choose 2
priority channels to scan. |
|
|
Like having two radios in one, the dual receive function
allows you to receive and listen to two different
channels simultaneously . |
 |
Screen Display |
|
 |
Receiver Only |
| |
An LCD screen allows users
to view channels, call up stored information and
navigate through the radio’s features. |
|
|
In some special cases, you only need to receive and do
not need to transmit, then you can enable this function. |
 |
Signal Strength Indicator |
|
 |
Channel Alias |
| |
The Signal Strength
Indicator measures the amount of power present in a
radio signal. It is an approximate value for signal
strength received on an antenna. |
|
|
Allows the user to give each channel a user defined
name. |
 |
Power Adjustable |
|
 |
Channel Step |
| |
This feature allows you to
switch between high and low power modes on the radio(25W/10W/4W). |
|
|
Channel refers to the
frequency value occupied when transmitting and
receiving. |
 |
Monitor |
|
 |
Wide/Narrow Band |
| |
This feature allows you to
check if a channel is clear before you transmit. |
|
|
Narrowband takes up less
frequency space and lowers the chance for interference,
wideband channels can carry more infos but require more
power. |
 |
Scan |
|
 |
Priority Scanning |
| |
The channel scan feature
enables a two way radio to continuously scan each
channel for activity. |
|
|
During the scanning process,
the set priority channel is scanned first. |
 |
Key Lockout |
|
 |
Auto Power Off |
| |
When activated this feature allows the user to lock the
buttons so that in case the user presses them by
mistake, it does not result in some unwanted action. |
|
|
In order to extend the life of the battery, when
activated, these radios will automatically turn off when
they are inactive for a period of time. |
 |
Busy Channel Lockout |
|
 |
Time-out Timer |
| |
This feature keeps
communication lines open by preventing radios from
listening or transmitting through conversations outside
their talkgroup. |
|
|
This feature will stop the
transmission of the two-way radio if the radio is
transmitting for a long duration. |
 |
Transmit Inhibit |
|
 |
PTT ID |
| |
Prevents transmission on a channel, basically making it
a 'receive only' channel. |
|
|
This feature allows the radio to transmit and/or receive
a radio ID and lets you know who is transmitting to you. |
 |
Private Call/Group Call/All
Call |
|
 |
Stun/Kill/Revive |
| |
Private Call allows a radio user to place a call to just
one user, Group Call provides voice call service in a
group. |
|
|
Stun and Kill disables a radio over the air and Revive
restores the disabled radio. |
 |
Talk Around |
|
 |
Reverse Frequency |
| |
A radio communicates through a repeater to bypass it and
communicate directly to the radio on the other end of
the connection instead. |
|
|
Reverse works by swapping the two frequencies. The
transmit and receive frequencies of the active channel
are exchanged or reversed. |
 |
Offset |
|
 |
Noise Reduction |
| |
Offset is the difference between a radio channel's
receive and transmit frequencies. |
|
|
Noise reduction is the process of removing noise from a
signal, in order to improve background sound quality to
be clearer. |
 |
Power-On Password |
|
 |
Voice Prompt |
| |
A power-on password can be a login password. Once it's
set, without it you will be unable to turn on your radio
or login system smoothly. |
|
|
The radio actually talks to you in a human-like voice.
You will hear the prompt spoken in plain relative
language. |
 |
Keypad Tone |
|
 |
Roger Beep/Talk Confirmation
Tone |
| |
Pressing a single key of keypad produces a sound to
remind that you already successfully press this key. |
|
|
When this feature is activated, a tone is transmitted to
the listener after a transmission. |
 |
1000/1450/1750/2100Hz |
|
 |
Silent Mode |
| |
1000/1450/1750/2100Hz is used to connect to the repeater. |
|
|
In silent mode, the radio will indicate an incoming
transmission without making an audible alert of any
kind. |
 |
NOAA Weather Alerts |
|
 |
CTCSS/DCS |
| |
This feature will give you the latest NOAA weather
information delivered to your radio real-time. |
|
|
CTCSS uses continuous tones below 300 Hz whereas DCS
uses digital data and all encoded words can be used on
the same channel without interference. |
 |
DTMF |
|
 |
2-Tone |
| |
DTMF is a technology that
uses a combination of tones to perform a number of
useful signaling operations. |
|
|
This feature employs a sequential transmission of 2
audible tones, enabling the receiver to hear an alert
tone. |
 |
5-Tone |
|
 |
MDC1200 |
| |
Similar to 2-tone, the 5-Tone is used to enable alerts,
alarms, send IDs, and many other functions. |
|
|
It uses short bursts of 1200
baud AFSK data to perform functions like PTT-ID and
Selective Calling. |
