( Ex : noisy road, motor bike, factory etc. ) To Set the VOX mode * Press the MODE button until the [Uo oF Or XX] appears. XX is a vox level * VOX icon will be appeared on the LCD. To Set the VOX level * Press the up[″]or down[…] button to set the VOX level from 1 to 5. “ oF” is disable the VOX function. “ 01” is least sensitive. “ 05” is most sensitive. * Press the PTT button or MODE button to confirm.
To set the Out of Range * Press the Mode button until [ir on or oF] and the Out of Range icon blink on the LCD. * Press the up[″]or down[…] button. * Press the PTT button or MODE button to confirm. 8) Setting ID code To set the Caller ID ! Press the MODE button until the ID Icon and small segment display blinks. ! Then press the Up or Down button to select the desired ID number from 01 to 10. “ oF” means no ID mode. ! Press the PTT button or Mode button momentarily to confirm the ID number.
* if there are no more receiving signal for 5 seconds, the unit will go into power save mode. 12) Receiving The Coding feature reduces the possibility of interference and provide enhanced Communication. You can only listen to a call that has correct matching code. ** Upon receiving a signal, the LED lights green. When radio is on CTCSS mode and then a signal that has different CTCSS code on the same channel is received, the LED blinks in green.
The lock function is to avoid the accidental changes to channel with other radio settings. All buttons will be locked except the Power, PTT, Monitor, Charger and Volume UP/Down. To lock the keypad * Press and hold the “ SCAN” button for over two seconds. * Keypad will lock.
