Supper Features
1,Push to Talk
While switching to another channel, you can hear the voice annunciation of the current channel number.
2,Wide Communication Coverage
High transmit power accommodates wide communication coverage up to 6Km in open area.
3,Monitor
To monitor whether the current channel has signal, press the MONI key. The MONI function is to receive weak signal.
4,50 Channels
5,CTCSS,CDCSS,PTT ID (DTMF encode)
To prevent unwanted conversations on the same frequency.CTCSS/DCS encoder and decoder can prevent interference on the same frequency from other communication groups.
6,Channel Spacing Selectable(25KHz/12.5KHz)
Different channel spacing 25KHz/ 12.5KHz is optional to conform with the regulations of different counties.
7,LCD and Keypad
the keypad and LCD can be used to programming the radio's parameters while the programming cable is not available.
8,Channel Annunciation
Channel Annunciation offers convenience to users in special applications, such as working in the darkness. The annunciation could be programmed in different languages.
9, Squelch Tail Elimination
The function will minimize the annoying audio outputs that occur at the receiver on completion of a transmission
10,Multi mode Scanning
Scan channel is convenient for the team leader to monitor the on-site situations. The scanning mode and scanning priority is programmable
11,busy channel lockout
BCL is used to prevent the interference with the on-going conversation. If BCL is in the "Open" state, when you press the PTT button, the radio will not transmit signals and remains in the receiving state to avoid interfering others that are in communication. If BCL is active, the radio could not transmit on the busy channel.
12,high/low power switchable
Different channel spacing 25KHz/ 12.5KHz is optional to conform with the regulations of different counties
13,VOX(Voice Operated Transmission)
VOX allows hands-free transmission on the radio when using the appropriate earphone/headset
14,TOT Function available
Time-out -timer can stop the transmitting automatically by presetting time limit to avoid any damage caused by long-time continuous transmission.
15,Auto power saving
Auto power-saving function set by PC software can extend the life of battery.
16,Low battery alert
17,Data Clone
To quickly set the parameters on a radio, your can clone the radio data from another radio with the supplied data cable, saving the time of parameter setting.
18,PC Programming
Frequency and various features can be set by programming software.
19, Squelch levels setting
The purpose of squelch is to mute audio output from the speaker when no signals are present. The higher the squelch level selected, the stronger the signals must be to receive. The appropriate squelch level depends on ambient RF noise conditions.
20.The Li-Polymer battery prolong the stand-by time and talking time, and avoid those accidents and possible danger in general battery.
