ABOUT RANGE
Your GXT Series radios are designed to give you maximum range
under optimum conditions.
Optimum Conditions are:
● Over water
● Open rural areas without obstructions
● Flat areas where you can see the other person
To ensure you get maximum range:
● Be sure to use fresh or fully charged batteries - low batteries will
cause low power conditions
● Be sure you are on a GMRS channel - FRS channels are
restricted by the FCC to low power
● Be sure to set your radio to use Hi power.
