Using Headset
You can make or answer calls with handsfree convenience using an optional headset with a 3/32-
inch plug (not supplied, available at your local RadioShack store) To connect a headset, insert
the headset’s plug into the MIC/SPK jack on the right side of the radio.
Note: Do not change your headset’s mode (VOX or PTT) while the radio is in use and be
sure to switch your radio off to reset it before switching between VOX and PTT.
Caller ID Operation
The Caller ID data includes the Transmitter ID and Receiver ID information. The Transmitter can
select the Receiver radio ID number who wants to call, and the Receiver radio will only receive
the Caller ID data who is addressed. The Caller ID data communication is based on the same
Channel and CTCSS code setting. The communication can not establish if the Channel and
CTCSS code are not the same.
Caller ID data is sent when user presses CALL key. The radio will transmit Caller ID data to the
desired radio. At the same time, other radio will check the receiving Caller ID data at the same
Channel and CTCSS code. If the Call ID number matches with its Home ID number (Receiver ID
number) or equal to Group Call, then it represents the call is addressed to this radio. As a result,
the receiver will display the Sender ID number on the LCD and generate Call melody. There are
five different Call melody to let user distinctive who transmit a Call (Please refer to the Call
melody note later).
After Caller ID transmission is completed, both radios (Transmitter and Receiver) will change its
CTCSS code setting to Private code for 15 seconds. It is used to avoid interruption from original
Channel and CTCSS code. In the 15-second period, both radios can only transmit and receive
voice message at the original Channel with Private Code. Besides the ID icon on both units will
be flashed on LCD to indicate this 15-second period. When conversation is made within this
period, the 15-second timeout will be extended for another 15 seconds. To exit the 15-second
period, press CALL key or waiting the 15 seconds timeout.
After 15-second timeout, both radios will restore to their original settings and LCD display will
revert back to the display without Caller ID function. On the other hand, if the receiver hasn’t
press any key after a Caller ID is received, its LCD display will keep on showing the received ID
number and MISS ID icon flashed until any key is pressed (except FUNC key). Also, reminder
beep will be generated to remind user that there is an incoming call and it will be beep once every
10 minutes for a period 30 minutes. It will be removed when the user pressed any key except
FUNC key.
