Setting the Level Meter Mode to ON permits the Remote Microphone's level meter LED to indicate the input
signal level only while announcements are made from the microphone. Microphone input sensitivity can
be correctly adjusted by speaking into the microphone while observing the LED level indication. When the
microphone is not used for announcement broadcasts, this LED provides normal indications (i.e. Programmed
function key operations).
