Audio Control Panel

Also from: ACP

There are 3 ACPs, each next to an RMP.

There are 2 ways to make a PA: press and hold the PA transmission key, or use the cockpit PA handset.

Controls

RESET	used to silence any buzzer and extinguish the flashing amber call light (such as for SELCAL), otherwise there is an automatic reset after 60s
VOICE	suppresses navaid ident (such as for and ATIS on a VOR frequency)

If nothing can be selected on an ACP, the AUDIO selector on the SWITCHING panel must be selected to the failed side.
