Key Features


Advanced Audio Technology
special voice compression and low level expansion technology enable crisper, clearer and stronger audio quality, allowing you to keep communicating even in a noisy environment.


Emergency Alarm/Siren
Meeting the need for urgent communication in critical situations, the easy-to-use, one touch emergency button emits a piercing alarm providing users with instant help alert.


Switchable RF Power level
By just pressing one button, users can switch to a low power when communicating within limited range coverage or switch to a high power level when further distance is required. High transmit power optimises range coverage while a low transmit power conserves battery consumption.


Users have the freedom to communicate through a repeater for wide area coverage, or bypass a repeater and talk directly to another radio if the coverage is within the range or when the repeater fails.


Tight/Normal Squelch
Users have the flexibility to protect their communication by selecting to a tight squelch to filter interference of unwanted weak signal; or switch to normal squelch to increase coverage.


14-Character Alpha Numeric Dot Matrix display
The 14 character Alpha Numeric display allows immediate communication of vital information such as PTT ID, radio strength indicator and signal strength indicator. In addition, the user-friendly icons make the information easy to read and understand. The keypad and display illuminations also provide the visibility to operate your radio in the dark.

Received Signal Strength Indicator
An easy to read on screen display indicator notifies users of signal strength in their vicinity.


Name & Tone Tagging
The capability of assigning 8 different ringing tones and visual caller IDs to 8 specific users/talkgroups enhances audio and visual caller identification for these 8 groups.


Battery Strength Indicator
Easy to read on-screen LCD display indicator alerts users on low battery strength.


128 Channels
Provides up to a maximum of 128 channels providing greater flexibility in organising different work groups


This feature enables you to replace frequently used voice calls with status messages, saving you valuable communication time.


Call Alert
If your call to a radio has no response, the radio will emit an alert tone until the other party takes action.


Voice Selective Call
The radio users receive a unique individual or group voice message with an alert to indicate that it is a selective call.


Priority Scanning
Allows activity on different channels to be monitored. Any incoming call will be automatically switched to another available channel so that the call can be received.
