3 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 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.  
3.1 
EFFICIENT RADIO OPERATION 
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.  
 
 
Do NOT hold onto the antenna when the radio is powered on! 
3.1.1 
Antenna Care and Replacement 
 
 
Do not use the portable radio with a damaged or missing antenna. A minor burn 
may result if a damaged antenna comes into contact with the skin. Replace a 
damaged antenna immediately. Operating a portable radio with the antenna missing 
could cause personal injury, damage the radio, and may violate FCC regulations. 
 
 
Use only the supplied or approved antenna. Unauthorized antennas, modifications, 
or attachments could cause damage to the radio unit and may violate FCC 
regulations. (Refer to Table 6-1.) 
3.1.2 Electronic 
Devices 
 
CAUTION
 
RF energy from portable radios may affect some electronic equipment.  Most modern 
electronic equipment in cars, hospitals, homes, etc. is shielded from RF energy.  However, 
in areas in which you are instructed to turn off two-way radio equipment, always observe 
the rules.  If in doubt, turn it off!
