ASP optical sight won't light what am i missing

[rooster328]

I'm doing the manual startup but the optical sight won't light even though i have the Gun Sight Power On and the Pipper and Net switches on.

Am I missing another switch?

Thanks for the haelp

Are your Gyros on? Item 55 and 56 on page 42 and page 44 of the manual. Also check the brightness knobs.

I figured it out. The emergency Inverter switch must be left off It's beside the Giro Switches. I wonder why one would switch it ON then?
