DTMF FUNCTIONS
This transceiver provides you with 16 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 right most column.
To perform Manual Dialing, follow the steps below.
1 Press and hold [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 and monitored through the speaker.
Frequency (Hz) 1209 1366 1477 1633
697 1 2 3 A
770 4 5 6 B
852 7 8 9 C
941 0 # D
• When DTMF TX Hold is ON, you do not need to continuously press [PTT] to remain
in Transmit Mode. However, Transmit 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.
AUTOMATIC DIALER
If you use the 16 dedicated memory channels to store DTMF codes, you do not
need to remember a long string of digits.
STORING A DTMF CODE IN MEMORY

2 Rotate the ENC control to select your desired DTMF memory channel number
from 0 to F.
