another button is used as a multicall button to send address and/or status digits, either selected
from the address and status lists or entered on the keypad. The GM340 can only send
pre-programmed telegrams.
External call buttons or switches can also be programmed to the accessory connector. (See
Accessory Connector section.)

Telegram on PTT
All GM300 Series radios can generate an encode telegram, either manually from one of the call
buttons, or automatically tied to PTT operation. When the PTT is pressed, PTT Keyup Mode
automatically sends the telegram:
Every PTT - The radio sends the telegram on every PTT press. This is often used to generate an
identity (PTT-ID) so that each transmission can be monitored by the system.
Once Only - The radio sends the telegram just once at the beginning of the call, eg to call another
radio. The sequence is not sent again until the call ends (monitor button pressed) or the Auto Reset
time expires.
