HTX-400 Mini Handheld 70-Centimeter FM Amateur Transceiver
(190-1104)                 Operation II               Faxback Doc. # 61416

Scanning Operation

Scanning For Active Frequencies

1.  To search for activity on a frequency, press SC.  The transceiver
    begins to scan up or down the full frequency range, and it stops on
    each active frequency for the duration set by the scan delay option
    (see "Using Scan Delay" below).

2.  To change the scanning direction, press /\ or \/.

3.  To stop on a frequency or to stop scanning completely, press SC again.

Using Scan Delay

If the HTX-400 stops on a signal during scanning, then that signal stops, 
the scan delay feature delays the continuation of scanning to allow time 
for the signal to restart.  Access the Main Menu (see "Using the HTX-400's 
Menus" in Faxback Doc. # 61413) to set the value.  With Sd and the current 
delay time shown, press /\ or \/ to select the new delay time (between 1 
and 30 seconds).

Scanning Standard Memory Locations

1.  Press MR (so [MR] appears), then press SC.  The transceiver scans all 
    locations except empty locations and the ones you programmed to be
    passed during scanning.

2.  To change the scanning direction, press /\ or \/.

3.  To stop scanning, press SC again.

Setting A Memory Location to Always Skip During Scanning

The HTX-400 is preset to include all memory locations (except empty 
locations) during memory scanning.  Follow these steps to set the 
transceiver to have it always skip (or resume scanning) a specific 
location during scanning.

1.  Press MR.  [MR] and the last used memory location appear.

2.  Repeatedly press /\ or \/ to select the desired memory location.

3.  Press FUNC + MR.  The selected memory location and [MR] flash.

4.  To set the HTX-400 to skip the memory location, press SC, then press
    \/ or /\ so SCSP ON (scan skip) appears.

    To include the displayed location during scanning, press \/ or /\ so
    SCSP oF appears.

5.  When you finish, press SC again, then press PTT to store the setting.

Temporarily Locking Out (Skipping) Locations During Memory Scanning

You can set the transceiver to lock out a location while scanning the 
frequencies stored in memory.

When the transceiver stops at a memory location you want to skip, press 
FUNC.  PASS briefly appears and the transceiver continues to scan, locking 
out (skipping) that location from then on.  Repeat this for each location 
you want to skip.

To cancel the settings and have the HTX-400 include the skipped 
frequencies once again, turn the radio off then on again.

Note: You cannot lock out all memory locations.  One location is always
      active. If you lock out all but two active locations and then lock
      out one more, EMPTY briefly appears and scanning stops.

Continuous Tone Coded Squelch System Features

Your HTX-400 can transmit and receive a low-level, selectable subaudible 
tone at the same time as it transmits (TX) or receives (RX) a regular 
signal.  This special tone lets you listen only to other radios set to the 
same tone frequency when you use the HTX-400 in simplex operation. It also 
lets you match your radio to the subaudible tone frequency used by a local 
repeater.

To enable the TX and RX tones for the HTX-400, follow these steps.

1.  Press FUNC + \/.  The current tone setting appears (tONE oF or tone
    on).

2.  Press \/ or /\ to turn on the option.  tone on appears.

3.  To set a receive (RX) tone, press FUNC + \/. rC appears. Then press \/
    or /\ to select a tone frequency from the list below. For this example
    67.0 MHz was selected for both the transmit and receive frequencies.

4.  To set a transmit (TX) tone, press FUNC + \/.  tC appears.  Then press
    \/ or /\ to select a tone frequency from the list below.

5.  Press PTT to store all the settings.

To select and store a CTCSS subaudible tone in a memory location, press 
MR.  [MR] and the last used memory location appear.  Then follow the 
preceding Steps 1-5.

Tone Paging

You can set the HTX-400 to sound an alert tone when it receives a 
transmission that includes the currently set subaudible receive-tone (or 
any transmission, if the receive-tone or the tone feature is set to off).  
Turn off the radio, then press (*) while you turn the HTX-400 on again. 
(Bell Symbol) appears.

The first time the HTX-400 receives a transmission that matches the 
current CTCSS settings, it sounds the selected alert tone, then turns off 
the tone paging feature.  To turn the feature back on, turn the power off 
then on again while holding down (*).

Follow these steps to change the alert tone.

1.  Select the VFO mode.  (See "Selecting Frequencies (Direct Tuning)" in
    Faxback Doc. # 61415.)

2.  Hold down FUNC and press \/ (T. SET) four times. MEL and a number from
    1 to 5 appear.  Release FUNC.

3.  Repeatedly press either \/ or /\ to step through the five different
    tones.  If key tone is enabled, each tone sounds as you select its
    number.

4.  Press PTT to store your selection and exit the menu.

Sending Paging Tones

To transmit the selected paging tone, press (*) while pressing PTT.
