Using DTMF Auto Send

If you turn on the DTMF auto-send feature, the HTX-242 automat- ically sends the sequence stored in the currently-selected DTMF memory every time you press PTT.

Follow these steps to turn on auto send.

1.Press VFO.

2.Hold F for at least 1 second. FUNC flashes.

3.Press MR.

4.Repeatedly press ▲ to select the dA option. Then rotate TUNE, or press UP or DOWN on the microphone, to set the option to on.

5.Press MR or PTT to save the setting.

6.Press DTMF so DTMF is on the display.

To temporarily turn off auto send, press DTMF so DTMF is not on the display. To turn off auto send, set the option to oFF in Step 4.

Notes:

•This feature works with the DTMF page feature. If you stored a sequence in DTMF Memory 0, the HTX-242 does not pass trans- missions to the speaker until it receives that sequence. After the

!transmission, DTMF squelch is still turned on.

•If there is no sequence stored in DTMF Memory 0, the HTX-242 still transmits the currently selected DTMF memory sequence each time you press PTT, but passes all transmissions to the speaker.
