LOW BATTERY WARNING!
Last updated: 15 April 2012
Mike here: Consider this a "better safe than sorry" warning. I have never had this problem with any of my AutoStars. If you have, please let me know at email@example.com. Thanks.
Subject: Autostar Quick Battery Check Sent: Monday, August 8, 2011 05:59:37 From: Mike Hogan (firstname.lastname@example.org) I've noticed that you often recommend changing batteries or power source as the first step when troubleshooting many problems. If the Autostar is working, there is a quick way to check the status of the power using the 'Status' Menu (MODE for 2 seconds). The last item in the menu is 'Battery Level' and shows voltage of the power source as a percentage. I've found that the 'scope may start behaving erratically when this value drops to about 75% but I recharge my external Power Pack when it falls to 85% just to be on the safe side. If the level falls too low, it can corrupt the memory, requiring a RESET or even a reload of the ROM. Just thought I'd pass this along. Regards, Mike HoganMike here: If low battery power can corrupt the memory, that could be a serious problem with the AutoStar #494, which does not have a user reload ROM capability.
I don't have any experience with the #494 so don't know if low power will have the same effect. I know my #497 got corrupted once and I think it was low power but can't be 100% positive.

I juts wanted to add to the low battery problem, and how it can relate with a 494 autostar. A few weeks ago i bought a etx 70at from ebay. When i got the scope it looked great, i then found the flip mirror had come unglued and was lodged below the flip holder. I used your site and repaired it myself (thank's to this site) I powered up the scope (a battery was already in it and when i flipped the switch i came on so i went with it. The autostar went through setup screens and then tried to slew to cirrus. After playing with it for awhile during a slew the screen keep flickering, would even go out for a bit, then come back on. Then it gave me a motor fault. SO it went to train motors then died again in the middle of this. Come to find out the person i had bought the scope from must have lost the battery pack and just had a single 9 volt installed. I ordered a external dc adapter and ac kit, and now use a jump start battery pack with the dc adapter which works great. But i think the low power must have fried my 494 autostar, because it go's through the setup menus, but gets stuck at daylight savings time. All i can do is use the autostar to control the scope which it still does. So i think the low power did fry it. I have a new 494 controller should be here tomorrow sure hope this one does not get fried to, but after reading what i have here, i think it was the 1 9 volt battery and being under powered. Hope this helps someone else not to fry there 494 (there hard to find)
