POWER SAVE CIRCUIT
This part of the operation of the radio is completely automatic and not adjustable. When the radio
has not transmitted or received a signal for several seconds it will begin to cycle from a sleep
mode to fully on. This occurs several times a minute. If a signal is received or you cause the radio
to transmit, the radio will become fully on. This cycling from sleep to fully on increases the battery
life more than 50%. An icon in the upper right of the display flashing “SAVE” will verify this.

RANGE OF UHF RADIOS
The best range between portable UHF radios is achieved when they are operating in open terrain
outside of buildings and vehicles. Anyone using a portable unit inside a vehicle will experience a
significant loss of range.
