Transmitter Alignment Options

Note: The maximum available power level given in the table below must NOT be exceeded.
There are separate alignment procedures for High and Low power.
Note: When checking the RF power output of the radio with a test set, always use a pad of
at least 30 dB attached to the radio end of the RF cable. This will avoid an RF
mismatch and ensure a stable RF reading that will not change with varying lengths of
connecting cable.
