DUAL TONE MULTI-FREQUENCY (DTMF) FUNCTIONS
This transceiver provides you with 10 dedicated DTMF
Memory Channels. You can store a DTMF number (16
digits max.) in each of these 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
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).
To perform Manual Dialing, follow the steps below.
1 Press and hold Mic [PTT] to transmit.
2 While transmitting, press the keys in sequence on the
keypad, to send the DTMF tones.
• The corresponding DTMF tones are transmitted.

• When DTMF TX Hold is activated {page 51}, you do not
need to continuously press Mic [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.
