OPERATING TIPS
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 or steel 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 that 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.
EFFICIENT RADIO OPERATION
Hold the portable radio approximately three inches from
your mouth and speak into the microphone at a normal
voice level.
Keep the antenna in a vertical position when receiving
or transmitting a message.
Do not hold the antenna when receiving a message
and, especially, do not hold when transmitting a message.
