Radio Shack HTX-202 - DTMF Squelch and Auto-Reply

Transmitting a DTMF Memory Sequence
To send a DTMF memory sequence, press and hold down PTT. Then, press D
followed by the DTMF memory number you want to transmit (1-5). The trans-
ceiver transmits the tones.
The transceiver has two DTMF memory sequence transmit speeds. To switch be-
tween fast and slow, press and hold down PTT. Press D. Then, press O.
Note: If the auto-reply feature is turned off, you can release PTT after you press
D. Enter the DTMF memory number within 1.5 seconds.
Using DTMF Squelch for Paging
The DTMF squelch feature lets you set your transceiver to release the squelch
only if it receives a specific touch-tone sequence. Follow these steps to set the
touch-tone sequence.
1. Press F+D-—SQL for at least 1 second.
The transceiver displays the previous sequence or — if you have never
programmed a sequence.
2. Enter the sequence (up to five digits).
3. Press PTT to save the sequence.
To turn on the DTMF squelch, press F+D-S@QL for less than 1 second. DTMF
appears in the display.
Your transceiver remains silent until it receives the correct touch-tone sequence.
Then, it beeps and returns to normal operation. To cancel DTMF squeich, press
F+D-SQL for less than 1 second so that DTMF disappears from the display.
Automatically Sending a DTMF Reply
You can set your transceiver to automatically transmit the touch-tone digit ( # )
when you have enabled DTMF squelch and the transceiver receives the correct
touch-tone sequence. To turn on the DTMF auto-reply, follow the steps in ‘‘Un-
derstanding the Configuration Menu” to display Ar. Then, rotate TUNE to select
on.
You should also set this option to on if you expect an auto reply from an autopatch
or another HTX-202 or other transceiver that has this feature.
