Using The Radio

To turn the radio on or off, hold down POWER for about 1 second.

To hear everything happening on a channel, including weak transmissions
and radios set to a different quiet code, hold down MON (monitor).  RX
appears.  Release MON to turn auto-squelch back on.

To talk, hold down PTT (push to talk) and speak into the microphone.  TX
appears.  When you finish speaking, release PTT.  TX disappears.

Rotate CHANNEL/QUIET/VOLUME to adjust the voice volume, channel, quiet
code, and ringer volume.

For more convenient listening, connect an optional speaker/microphone with
a 3/32-inch mini plug and a 1/8-inch plug to the EAR/MIC jacks (or an
earphone with a 1/8-inch plug to the EAR jack).

Repeatedly press MODE to switch between channel, quiet, volume and
intelligent call ringer modes.  See "Using the Quiet Feature" below.

You can lock the radio's volume at any time by holding down MODE for 2
seconds.  (key) appears, and you cannot use CHANNEL/QUIET/VOLUME to adjust
the volume.  Hold down MODE again for 2 seconds to unlock the volume.
(key) disappears.

As you use the radio, the battery icon's elements on the display disappear
to show how much power remains.  When only one element remains, recharge
the battery pack or replace the batteries.

You can cause a paging tone to sound on all radios tuned to the same
channel (and quiet code, if used).  To send a page, hold down CALL for up
to 5 seconds.  TX appears.

When you press CALL, the radio sends a signal that automatically turns up
the volume on another Cat. No. 21-1810 Two-Way Family Radio (or other
radio that has this feature).  This "Intelligent Call Ringer" allows the
party on the other end to hear the call tone, even if their radio's volume
is set to its lowest setting.

The backlight turns on for 10 seconds whenever you press MODE, CALL, or
POWER, or rotate CHANNEL/QUIET/VOLUME.

To attach the belt clip, slide the belt clip onto the tab on the back of
the radio.

Using The Quiet Feature

The quiet feature lets you talk and listen to people who are using other
radios set to the same channel and quiet code as your radio.  This is like
having a sub-channel within a channel, giving you greater communication
flexibility.

When you set a quiet code (there are 38 to choose from) and turn to this
feature, the radio transmits a tone with your transmission.  This tone is
too low for you to hear, but other radios can detect it.  This prevents
radios which are not set to the same channel and quiet code from
interfering with your transmissions or reception.

Follow these steps to set a quiet code.

1.  Repeatedly press MODE until QUIET flashes and the previously set quiet
    code appears.  

2.  Rotate CHANNEL/QUIET/VOLUME knob clockwise or counterclockwise until
    you see the desired code number (1-38).  Then press MODE to save the
    desired quiet code.

    QUIET flashes for 5 seconds after you stop rotating CHANNEL/QUIET/
    VOLUME knob, then the selected channel number reappears.
