DTMF FUNCTIONS
This transceiver provides you with 10 dedicated DTMF memory
channels. You can store a DTMF code (16 digits max.) in each of
these channels to recall later for speed dialing.
Manual Dialing
The numeric keypad functions as a DTMF keypad; the 12 keys
found on a touch-tone phone plus 4 additional keys (A, B, C, D) on
the rightmost column.
To perform Manual Dialing, follow the steps below.

• When DTMF TX Hold is ON, you do not need to continuously
press
[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.
