2. Turn the unit "on" by rotating Volume Control clockwise.
3. Set the Channel Selector to the desired channel.
4. Set the Volume Control to a comfortable listening level,
5. Listen to the background noise from the speaker. Turn the Squelch Control slowly
clockwise until the noise JUST disappears (no signal should be present). Leave the
control at this setting. The Squelch is now properly adjusted. The receiver will
remain quiet until a signal is actually received. Do not advance the control too far,
or some of the weaker signals will not be heard.
RANGE
The range of your hand-held transceiver will vary depending on conditions. Factors
such as antenna, terrain and battery charge all affect range. To insure maximum range,
always keep fully charged batteries in the unit. As voltage decreases, it directly affects
range. Though higher in initial cost than other types. Nickel Cadmium Rechargeable
Batteries are recommended. They can be recharged hundreds of times.
CHANGING OR INSTALLING NEW CRYSTALS
Your AX- 52 comes with Channel 14 installed in Channel 1 position. You can use any
3 channels of the 40 alloted to CB Band. Do not attempt to use non-standard crystals
or to make any internal adjustments to your AX-52. Such is prohibited by the D.O.C.
and result in illegal operation, for which you may be liable and may be fined. There
fore, replacing and/or installing crystals must be made by or under supervision of the
holder of an D.O.C. issued 1st or 2nd class radio operator license. Following informa
tion is provided only for such license holders,
1. Remove the rear cover from the transceiver.
2. Insert transmit crystal into the dual pin socket marked TX-2 or TX-3 (see below).
3. Insert receive crystal into the dual pin socket marked RX-2 or RX-3.

NOTE: The crystals installed in channel "1" position are also of plug-in type and may
be replaced with those of any other channels.
Make sure the transmit and receive crystals are installed in their correct
sockets. If the crystals are reversed, the unit will transmit on one frequency
and receive or another, both of which will be outside the citizens band,
resulting in illegal operation.
4. Replace the rear cover.
