OPERATING TIPS
Antenna location and condition is important when operating a portable
radio. Operating the radio in low 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 and buildings 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 use properly charge batteries.
For efficient radio operation, hold the front of 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.
