LED activity:

Do stations have LED activity? (Will switch between Green and Yellow when pressed)
Is the CR7 green LED on solid on the AAS CPU? (this is the station voltage indicator, which should be between 10.4 - 12.0 VDC)

Station voltage:

Do stations have 10.4 - 12V DC?
- Factory setting is 10.4V, but it can be increased to 12V if fader levels are not reaching full due to long wire runs to stations.

LCD screen activity:

Is there any information on the LCD screen? In monitor mode?

Fuses:

If F1 blown, AAS will not boot and LCD screen will not turn on
- CAUTION: AC power will be still present at the terminal block and on the AC nuetral line.
If F2 blown, Stations will have no power and green LED above red switches will be out.
For fuse details, see article: Fuses on the AAS (Analog Address System), AAS (Analog Address System) - Not Functioning

Software Setup:

Is console mode set correctly?
Is patch correct?

Red Switches:

Does anything change when you toggle them?

[Reset\Normal]	Resets AAS processor
[Term on\Term off]	Terminates DMX input
[Bypass\Normal]	Bypasses DMX input

Gray Switches:

To Clear All (patch 1 to 1, Fade Time = 00, Console = Disable):
- While continuing to hold down ENTER, move SW1 to Reset then back to Normal. Do not release ENTER until the screen says, “OK, release” (“Clear All” is shown before “Ok, release”)

- While continuing to hold down DIMMER UP, move SW1 to Reset then back to Normal. Do not release DIMMER UP until the screen says, “Ok, release” (“Build Default” is shown before “Ok, release”)
