DUAL TONE MULTI-FREQUENCY (DTMF) FUNCTIONS
The keys on the keypad also function as DTMF keys; the
12 keys found on a push-button telephone plus 4
additional keys (A, B, C, D). This transceiver provides
10 dedicated 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 a quick
call.
Some 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.

tones.

2Press the keys in sequence on the keypad to send
