the RMU will leave its normal operating mode and displays a menu that
the operator can use to enter a maintenance mode of operation. This
menu can be called up only when the aircraft is on the ground. During
this mode, various pages are used to give maintenance personnel
access to software versions, strap option settings, maintenance log
data and operating conditions of the radio system. Pushing the bottom
left line select key returns the RMU to the main tuning page.
Refer to the radio systems maintenance manual for additional information.

RMU Display Dimming

RMU display brightness can be adjusted using the tuning knob after the
DIM function button is pushed. The tuning knob returns to normal
operation when any function or line select key is selected. Setting
display brightness sets the bezel mounted light sensors with a
reference about which they adjust the brightness for varying lighting
conditions.
