F A strong environmental noise will greatly interfere with voice communication process when you use the public phone or a mobile phone in a noisy environment. So the noise reduction function can effectively improve the communication quality. Due to the high complexity of the problem and the high actual demand, the ambient

Main Features ANI VR-DB2R has ANI ID Code.
8 Groups Scrambler This function does not need any additional accessories. Any other party listening on your channel will be unable understand your conversation when activated.
Burst Tone There are 1750Hz, 2100Hz, 1000Hz and 1450Hz. These tones are mostly used for repeater.
2.5kHz STEP FOR VHF/UHF E n s u r i n g f u l l c o m p a t i b i l i t y with all channel loading requirements,the VR-DB2R synthesizer provides 2.5kHz resolution,channel programming is straightforward in all configuration situations.
Frequency Range Dual Band: 136-174MHz & 400-480MHz (We can make the special frequency range for any region of any country).
Standard Accessories
256 Channels（UHF128, VHF128） Wide(25kHz/20kHz) & Narrow(12.5kHz) There are 25kHz, 20kHz and 12.5kHz for users choose. The users can switch the wide band and narrow band by keypad.

Keypad & Potentiometer Lock on/off (Automatically / Manually) When activated,coding switch and keyboard disabled, channel will always stay on the current channel.
Multi-Scan There are 3 scan modes: Time, Carrier and Tone.
Optional Accessories
Channel Alarm VR-DB2R can choose a channel to set the Channel Alarm. VOX Function When this function is activated, without pressing [PTT] key, the transmit can be achieved through the appropriate voice.
