Manually Transmitting DTMF Tones

To transmit DTMF tones, follow the steps for transmitting. Then, while holding down PTT, press the digits on the microphone to transmit the tones.

Note: If auto-reply is turned on, you must hold down PTT while you trans- ! mit. If auto-reply is off, you can release PTT after you enter the first digit.

The HTX-242 transmits for 1 second after you enter the last digit. See “Using Auto-Reply” on Page 34.

Transmitting DTMF Tones from Memory

1.Press DTMF so the HTX-242 displays DTMF and the current DTMF memory number.

2.To select a different DTMF memory, press and hold F for at least 1 second. Then press DTMF.

3.Rotate TUNE or press ▲ or ▼ to select the desired DTMF memory.

4.Press and hold PTT. Then press DTMF to send the current DTMF memory.

Notes:

•If you turn on the DTMF auto send option and turn on DTMF mem- ory (DTMF appears on the display), the HTX-242 sends the DTMF

!sequence in the current memory every time you press PTT. See “Using DTMF Auto Send” on Page 35.

•To store DTMF sequences, see “Storing a DTMF Sequence” on Page 32.
