DTMF FUNCTIONS

This transceiver provides you with 10 dedicated DTMF memory channels. You can store a DTMF code (16 digits max.) in each of these channels to recall later for speed dialing.

Manual Dialing

The numeric keypad functions as a DTMF keypad; the 12 keys found on a touch-tone phone plus 4 additional keys (A, B, C, D) on the rightmost column.

To perform Manual Dialing, follow the steps below.

1Press and hold [PTT] to transmit.

2While transmitting, press the keys in sequence on the keypad, to send the DTMF tones.

The corresponding DTMF tones are transmitted and monitored through the speaker.

When DTMF TX Hold is ON, you do not need to continuously press [PTT] to remain in Transmission Mode. However, Transmission Mode is retained for only 2 seconds after pressing a key, so if the next key is not pressed within this time limit, the transceiver stops transmitting.
