HTX-212 Two-Meter Mobile Transceiver
(190-1125)                 Using Memory Channels      Faxback Doc. # 19134

Your HTX-212 has 31 memory channels (one calling-frequency memory and 30
standard memory channels).  See "DTMF and Subaudible Tones," Faxback Doc.
# 19133, Using DTMF and Subaudible Tones, for explanations of the
subaudible tone features.

USING THE CALLING-FREQUENCY MEMORY

With the press of a button, you can immediately select the settings stored
in the calling-frequency memory.

Follow these steps to store receive and transmit frequencies, transmit and
receive subaudible tones, and subaudible tone transmit and squelch in the
calling-frequency memory.

1.  Press CALL. M-CH and C appear, along with the current calling
    frequency.

2.  Press T-SQL to set the desired subaudible tone transmit and squelch
    operation (Faxback Doc.# 19133, "DTMF and Subaudible Tones").

3.  Press SHIFT to select the desired duplex offset.

4.  Press LOW to select either high or low power.

5.  Hold F for at least 1 second. FUNC flashes on the display.  Press
    CALL again. M-CH flashes.

6.  Enter the last four digits of the receive frequency.

7.  Press /\.  The HTX-212 displays "tF" and the current transmit 
    frequency.  If you want to change the transmit frequency, enter the
    last four digits of the desired transmit frequency.

8.  Press /\.  The HTX-212 displays "tc" and the currently selected
    transmit subaudible tone.  Rotate TUNE, or press UP or DOWN on the
    microphone, to select the desired transmit subaudible tone.  If you
    do not want a transmit subaudible tone, either leave the setting as
    is (and do not turn on the subaudible tone transmit feature in Step
    2) or set it to OFF.

9.  Press /\.  The HTX-212 displays "rC" and the currently selected
    receive subaudible tone.  Rotate TUNE, or press UP or DOWN on the
    microphone, to select the desired receive subaudible tone.  If you
    do not want a receive subaudible tone, either leave the setting as is
    (and do not turn on the subaudible squelch features in Step 2) or set
    it to OFF.

10.  Press CALL to save the settings and return to the call frequency
     memory display.

To use the calling-frequency memory, press CALL at any time.  Press CALL
again to return to the previously selected channel or VFO.

USING THE STANDARD MEMORY CHANNELS

The HTX-212 has 30 standard memory channels where you can store frequently-
used frequencies, along with duplex and subaudible tone settings, for quick
access.

Storing a Frequency

1.  Press VFO and tune to a frequency you want to store.  Set all duplex
    and subaudible tone settings, (see "Using Subaudible Tones," Faxback
    Doc.# 19133, DTMF And Subaudible Tones.

2.  Press F.  Then rotate TUNE, or press UP or DOWN on the microphone,
    until the HTX-212 displays the desired memory number to the left of
    the frequency.

3.  Press MR.  The HTX-212 beeps twice and stores all settings into the
    selected memory channel.

Changing Stored Settings

To change the receive frequency, follow the steps under "Storing a 
Frequency," above.  Follow these steps to change the transmit frequency
or a tone squelch option without changing the receive frequency.

1.  Press MR.

2.  Rotate TUNE, or press UP or DOWN on the microphone, to select the
    memory channel you want to change.

3.  If you want to turn tone squelch on or off, repeated press T-SQL to
    select the desired tone squelch mode.  (See "Using Subaudible Tones,"
    Faxback Doc.# 19133, Using DTMF and Subaudible Tones).

4.  Press F, then press MR.  The HTX-212 displays "tF" and the transmit
    frequency, and M-CH flashes.

5.  Rotate TUNE, press UP or DOWN on the microphone, or enter the desired
    transmit frequency using the microphone's keypad.

6.  Press /\.  The HTX-212 displays "tC" and the current transmit
    subaudible tone.

7.  Rotate TUNE, or press UP or DOWN on the microphone, to change the
    transmit subaudible tone.

8.  Press /\.  The HTX-212 displays "rC" and the current receive subaudible
    tone.

9.  Rotate TUNE, or press UP or DOWN on the microphone, to change the
    receive subaudible tone.

10.  Press MR.  The HTX-212 saves the new settings.

Tuning to a Memory Channel

1.  Press MR.

2.  Rotate M-CH, or press UP or DOWN on the microphone, to select the
    desired memory channel.

Checking Priority Channel 1

To have the HTX-212 periodically "look back" at Memory Channel 1 to check
for a transmission, press F then ALM. The alarm symbol (a bell) appears on
the display.  The HTX-212 looks back at Memory Channel 1 every 4, 8, 12,
or 16 seconds.  If there is a transmission, the HTX-212 beeps to let you
know to tune to it, if desired.

Follow these steps to change the look-back time.

1.  Press VFO.

2.  Hold F for at least 1 second. FUNC flashes.  Then press MR.

3.  Repeatedly press /\ until the HTX-212 displays "Lb" and the current
    look-back time.

4.  Rotate TUNE, or press UP or DOWN on the microphone, to select the
    desired look-back time (4, 8, 12, or 16 seconds).

5.  Press MR to save the setting.

Scanning Memory Channels

To set the HTX-212 to scan all memory channels, hold MR for at least 1 
second. M-CH flashes, and the HTX-212 scans the memories.  The HTX-212
stops when it encounters a transmission.  It resumes scanning according
to the saved scan settings (see "Setting the Scan Options," Faxback Doc.#
15169, Operation.

Clearing a Memory Channel

You can clear any memory channel except Memory Channel 1 and the calling-
frequency memory.

1.  Tune to the memory channel you want to clear.

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

3.  Press MR. All settings are cleared from the memory channel.
