I have a symbol 9090 scanner and when the batteris goes dead, it keeps loosing all the settings. I have exported the profile like I was told to do, but it still looses the settings. I am at a loss as to what to do. I have 17 of them that I am having to reset everyday.

Hello rcatron. I think I can help hammer-out your issue. The MC9090 has a backup battery similar to a BIOS battery on a PC motherboard. What this does is holds a constant charge so that the unit's settings are always active and ready to be recalled when it starts up. Generally speaking: if the settings aren't coming back after you reset the unit, it would mean that the backup battery has lost it's charge and with that the ability to hold the configuration (cache/flash) data. However, since all of your units are doing this (correct?) I highly doubt that all of their backup batteries have gone belly-up simultaneously. There a couple causes that immediately come to mind.

1. The backup battery draws it's charge from the main battery or power source just like a BIOS on a PC draws it's power from the power-supply even when the computer is "off". So, if you take the batteries out (maybe to charge them?) overnight or for extended periods of time, this would be your problem. If so, simply leave the batteries in the units or place them in the cradle whilst not using them for more than 5 hours or so.
2. When you say you are losing all the settings, are you referring to the general operating system settings (wireless network, backlight, and things like that)? Or are you talking about a custom application that you use for your inventory control? If it's the latter, then I recommend you make a call to your software provider and ensure that the settings are being properly saved and more importantly: in the right place. This could be an issue.
