1. Select menu item 04 R-MOD, option "QT + ANI" (speaker opening method).
2. Set the time of the ring signal by ANI-code, in the 24 RING menu item.
Personal call
Press the [PTT] key and hold it down and enter the ANI-code of the called station on the
microphone key pad. At the end of the dialing, transmit the necessary information by
voice.

12
Group call to specific stations
For example, the group contains stations with ANI codes: 12345, 12789, 23888.
You can only make a call to stations whose ANI code begins with 12.
To do this, press the [PTT] key and type [1] [2] [*] [*] [*] on the microphone keypad.
In this case, the call will not sound in the station with ANI-code starting with 23. Note.
An asterisk [*] can replace any code digits, or even all.
Remote control of the unit
Note! You must first program the control codes using a computer (CHIRP).
In the program, the tab "DTMF Groups" Factory recommended settings.
The length of the control codes can be from 1 to 7 characters.
The length of the control codes can be from 3 to 5 characters.
Reset, Transmit Inhibit, Complete Inhibit and Monitor codes must start with "#". The
master code must be the same as the identification code.
