USING DTMF AND SUBAUDIBLE TONES
Your HTX-212 has seven DTMF (Dual-Tone, Multiple Frequency—
another name for touch tones) memories where you can store DTMF
sequences. DTMF Memory 0 can hold a seven-digit DTMF paging
sequence your HTX-212 must receive for DTMF paging. DTMF Memories
1-6 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-212 displays td, DTMF 1, and the current
sequence stored in DTMF Memory 1.
3. Rotate TUNE, or press UP or DOWN on the microphone, to select
one of the six transmit DTMF memories (1–6) or the receive DTMF
memory (0).
Note: td appears before DTMF Memories 0–6, and rd appears
before DTMF Memory 0.
4. Press SHIFT. Then use the keypad to enter the sequence you want
to store.
Note: DTMF Memories 1–6 hold 15 digits each. DTMF Memory 0
holds 7 digits.
5. Repeat Steps 3 and 4 to store more DTMF sequences, or press
DTMF to save all sequences and return to normal operation.
Note: To clear a DTMF sequence, repeat these steps but do not enter a
frequency in Step 4 after you press SHIFT.
TRANSMITTING A DTMF SEQUENCE
1. If DTMF is not on the display, press DTMF.
Note: If the DTMF memory that contains the sequence you want to
transmit is already selected, skip to Step 6.
2. Hold F for at least 1 second. FUNC flashes.
3. Press DTMF.
4. Rotate TUNE, or press UP or DOWN on the microphone, to select
the DTMF memory that contains the sequence you want to trans-
mit.
5. Press DTMF.
6. Press the push-to-talk button. While holding down push-to-talk,
press DTMF. The HTX-212 transmits the stored sequence.
