DUAL TONE MULTI-FREQUENCY (DTMF) FUNCTIONS (WITH MC-53DM ONLY)
The keys on the Mic keypad 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.
MANUAL DIALING
Manual Dialing requires only two steps to send DTMF
tones.
1 Press and hold Mic [PTT].
2 Press the keys in sequence on the Mic keypad to
send DTMF tones.
• The corresponding DTMF tones are transmitted.
■ DTMF Monitor
When pressing the Mic DTMF keys, you will not
hear DTMF tones from the speaker. You can also
make the speaker output DTMF tones each time
you press a DTMF key.
