Battery Pack everytime you transmit to
determinewhetherthe power insidethe Battery
is still sufficient enough to support normal
Receive and Transmit communications.
When the PTT switch is pressed and the TX
LED blinks. It means the battery level is already
Iow and needs recharging. Under this condition,
the unit no longer transmits RF Power. Have
your battery charged fully or replaced by a fully
charged battery to resume normal operation.
