I have noticed the exact same output with the Bezel lighting.   In my case, I'm only using the photo sensor and not the dimming bus.   Using the "setup options" I changed the bezel mode from Auto to Manual and started to adjust the backlight.  When I got to about 50% and lower the label backlighting turned on.   Maybe Steve can chime in as to whether this is by design or a bug or ???. 

Auto Lighting strategy is confusing to me, especially since I'm only using the sensor and I'm having a hard time setting upper and lower levels.

Also, does anyone know if I can manually trigger the audible alerts on the ground, ie TOD chime, terrain alerts, etc.  I thought I had them, but on last flight didn't hear anything.


Thanks
