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.

6 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 55. Such is prohibited by the FCC
and result in illegal operation, for which you may be liable and may be fined. There
