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.

To perform Manual Dialing, follow the steps below.

• 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.

When pressing the Mic DTMF keys, you will not hear
DTMF tones emitted from the speaker. However, you
can monitor the DTMF tones if desired.
