4 OPERATION
Antenna location and condition are important when operating a portable radio.
Operating the radio in low lying areas or terrain, under power lines or bridges,
inside of a vehicle or in a metal framed building can severely reduce the range
of the unit. Mountains can also reduce the range of the unit.
In areas where transmission or reception is poor, some improvement may be
obtained by ensuring the antenna is vertical. Moving a few yards in another
direction or moving to a higher elevation may also improve communications.
Vehicular operation can be aided with the use of an externally mounted
antenna.
Battery condition is another important factor in the trouble free operation of a
portable radio. Always properly charge the batteries.
This device complies with Part 15 of the FCC Rules. Operation is subject to
the following two conditions:
1. This device may not cause harmful interference, and
2. This device must accept any interference received, including interference
that may cause undesired operation.

in areas in which you are instructed to turn off two-way radio
equipment, always observe the rules. If in doubt, turn it off!
4.1.2 Aircraft

Use it on the ground only with crew permission.
