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.
