Something is wrong if you don't have Auto Brightness. The LRH is spec'd to have it - all of the 2000+ models have auto and user adjustable "Lumatic" displays (the 850 and 1250 have "transmissive" displays). Either you're just jumping over it in the display brightness menu, or something is buggy in your programming - a call to Sig would get you straightened out though. They sent me an RMA for my 2000 when it wouldn't power on, and I had a replacement 2200MR in my hands within 10days - it was only in their hands for a day before the replacement was mailed out.
