20
Q

How many cryptos are available per radio?

A

19

21
Q

Do you have to wait until the VU2 power up BIT is complete before you apply AC Power (APU or AGPU)?

A

Yes. VU2 will not connect to the Data Bus otherwise

22
Q

A

CPG

26
Q

The right wing wingstation uses which crewstation’s master volume knob?

A

PLT

27
Q

Can you eliminate all noise by lowering the master volume all the way?

A

No. Master Warnings, Cautions, and Advisory audio tones can still be heard.

28
Q

How do you adjust brightness on the CCP?

A

In DAY mode use the brightness knob on the right MPD. Otherwise use the primary lighting knob.
