Instruction manual

PTT->B Pushing the PTT button half way through toggles the analog/digital
mode, continue and fully press the PTT to open the microphone and talk.
Voice squelch: Allows you to hear both analog and digital transmissions.
All digital: The only audio you will hear is when the ARD9000MK2 detects
and decodes a digital transmission.
(*): In FM mode, the ARD9000MK2 operates best when your transceiver
squelch is fully open.

Enables the re-synchronization of digital reception if synchronization is lost
during a communication session.

Adjustment for speaker output level of the speaker-microphone, as well as
for the speaker output on the rear panel. Turning the knob fully
counterclockwise switches the unit off.
