DTMF FUNCTIONS The keys on the keypad also function as DTMF keys; the 12 keys found on a touch-tone phone plus 4 additional keys (A, B, C, D). This transceiver also provides 10 dedicated DTMF memory channels. You can store a DTMF number (16 digits max.) with a memory name (8 digits max.) in each of the channels to recall later for speed dialing. Many repeaters in the U.S.A. and Canada offer a service called Autopatch. You can access the public telephone network via such a repeater by sending DTMF tones. For further information, consult your local repeater reference. MANUAL DIALING Manual Dialing requires only two steps to send DTMF tones. 1 Press and hold the PTT switch to transmit. 2 While transmitting, press the keys in sequence on the keypad to send DTMF tones. • The corresponding DTMF tones are transmitted and monitored through the speaker. • While pressing keys on the keypad, the transceiver remains in the TX mode. You do not have to press [PTT] at the same time. Freq.
