USING DTMF AND SUBAUDIBLE TONES
Your HTX-242 has 10 DTMF (Dual-Tone, Multiple Frequency—
another name for touch tones) memories where you can store
DTMF sequences. DTMF Memory 0 can hold a 7-digit DTMF paging
sequence your HTX-242 must receive for DTMF paging. DTMF
Memories 1-10 each hold 15 digits you can quickly transmit.
Storing a DTMF Sequence
1. Hold down F for at least 1 second. FUNC flashes.
2. Press DTMF . The HTX-242 displays the sequence stored in
the currently selected memory.
3. Rotate TUNE , or press UP or DOWN on the microphone, to
select one of the 10 transmit DTMF memories (1–10) or the
receive DTMF memory (0).
Note: td appears with transmit DTMF Memories 1-10, and
rd appears with receive DTMF Memory 0.
4. Press SHIFT . Then use the keypad to enter the sequence you
want to store.
Note: DTMF Memories 1–10 hold 15 digits each. DTMF
Memory 0 holds 7 digits.
5. Repeat Steps 3 and 4 to store more DTMF sequences, or
press
DTMF or PTT to save all sequences and return to nor-
mal operation.
Transmitting a DTMF Sequence
1. Hold F for at least 1 second. FUNC flashes.
2. Rotate TUNE , or press UP or DOWN on the microphone, to
select the DTMF memory that contains the sequence you
want to transmit.
3. Press the push-to-talk button. While holding down PTT,
