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.

• 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

1 Enter Menu mode and access Menu No. 28 (DTMF.MR), then press [F].

2 Rotate the ENC control to select your desired DTMF memory channel number

from 0 to F.

3 Press [F].

• The DTMF code entry display appears and the last digit blinks.

4 Rotate the ENC control to select a DTMF code.
