TX SAV E DISABLE
Press the assigned Programmable key to disable the
Transmit Battery Saver, if you are operating in a location where high power is almost always needed.
The Transmit Battery Saver helps extend battery life
by reducing transmit power when a very strong signal from an apparently nearby station is being received. Under some circumstances, though, your
