¡ª Highlights ¡ª

¡¡

Screen Display ¡¡ 4 Programming Keys
¡¡ An LCD screen allows users to view channels, call up stored information and navigate through the radio¡¯s features. ¡¡ ¡¡ You can program or assign to perform a user specific function. Personalize the required functions for convenient and quick operation.
Receiver Only ¡¡ Channel Alias
¡¡ In some special cases, you only need to receive and do not need to transmit, then you can enable this function. ¡¡ ¡¡ Allows the user to give each channel a user defined name.

Monitor ¡¡ Channel Step
¡¡ This feature allows you to check if a channel is clear before you transmit. ¡¡ ¡¡ Channel refers to the frequency value occupied when transmitting and receiving.
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.
Hands-free VOX ¡¡ Power Adjustable
¡¡ This hands-free feature allows you to get on with other manual tasks while you stay in touch with other users. ¡¡ ¡¡ This feature allows you to switch between high and low power modes on the radio.
Wide/Narrow Band ¡¡ Keypad Lockout
¡¡ Narrowband takes up less frequency space and lowers the chance for interference, wideband channels can carry more infos but require more power. ¡¡ ¡¡ 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.
Battery Saver ¡¡ Time-out Timer
¡¡ The radio will switch to automatically after being left unused for a certain amount of time, lessens the drain on your battery and makes it last longer. ¡¡ ¡¡ This feature will stop the transmission of the two-way radio if the radio is transmitting for a long duration.
Radio Check ¡¡ Time & Date
¡¡ If activated, this feature allows you to determine if other radios are active on the system without disturbing the radio user. ¡¡ ¡¡ It displays the current date and time on radio.
Contact List ¡¡ Call Log
¡¡ A contact list is a collection of screen names .To communicate with someone on the list, the user can select a name and act upon it. ¡¡ ¡¡ Call logging is the process of collecting, analyzing, and recording data on calls.
SMS ¡¡ One Key Call
¡¡ This feature allows you to send SMS text messages to other people in the group. ¡¡ ¡¡ This feature allows the user to make a call by pressing a special key.
Manual Dial ¡¡ PTT ID
¡¡ The users make a call by using the manual dial mode. ¡¡ ¡¡ 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.
Remote Monitor ¡¡ Repeater Capable
¡¡ This feature can secretly and remotely monitor the voice activities around a certain walkie-talkie device without notification. ¡¡ ¡¡ These radios are capable of being used with a repeater station, which can greatly increase your communications range and reliability.
Talk Around ¡¡ Digital Anti Cracking
¡¡ A radio communicates through a repeater to bypass it and communicate directly to the radio on the other end of the connection instead. ¡¡ ¡¡ Using the digital anti-cracking feature, you can realize the anti-cracking function and avoid receiving illegal signals.
Lone Worker ¡¡ 2 Time Slot
¡¡ This safety feature requires operators to check in at certain intervals of time. If the user does not check in within that time frame, an alert is triggered. ¡¡ ¡¡ 2 slot achieves two groups of calls at a frequency point at the same time so that the communication efficiency is doubled and frequency resources are saved.
Voice Prompts ¡¡ Low Battery Alert
¡¡ The radio actually talks to you in a human-like voice. You will hear the prompt spoken in plain relative language. ¡¡ ¡¡ This warning reminds that your battery is low and must be either recharged or replaced.
Emergency Alert ¡¡ Keypad Tone
¡¡ If an operator needs to send an immediate and urgent request for help, the push of just one button can trigger a call for assistance. ¡¡ ¡¡ Pressing a single key of keypad produces a sound to remind that you already successfully press this key.
Call Tones ¡¡ Silent Mode
¡¡ Call tones allow you to transmit a tone to other radios in your group to alert them that you want to talk. ¡¡ ¡¡ In silent mode, the radio will indicate an incoming transmission without making an audible alert of any kind.
CTCSS/DCS ¡¡ DTMF
¡¡ 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 is a technology that uses a combination of tones to perform a number of useful signaling operations.
