If you configure the 2800 to auto-power off after a time period, then power it on again, Memory Map is shown, but it will then either:
- crash with a Windows error popup
- freeze requiring a restart from scratch

So far as I can tell there's no way to turn off a 2800 and leave Memory Map running, then turn it on again - so this means you need to restart from scratch and start Memory Map each time.

Is there any way round this?

edwh,

On this forum somwhere is a reference to your post, basically the autopower off setting was never intended to be used with the adventurer
2800, remarks from simon indicate this was originally set up for third party apps, do not use this setting it will crash the unit.

this doesn't effect the backlight setting, which when set will allow you to get the most out of your battery, hope this helps

Thanks for your reply.

I tried leaving my 2800 on with the backlight setting set to minimum yesterday and can only get a few hours of life, which isn't enough for a whole day walking. The lack of a quick power off/on is a shame, because it's a step backwards from the RoadAngel 7000, where you could use the power button to turn it off and on with a single operation.

I know this isn't quite the answer you are looking for, but a spare battery from memorymap which i think attaches to the back of the unit doubles the quoted battery life.

Check out, how much battery life people are getting posted by Adventurer.
Some of those tests where carried out in very low temperatures. I have myself followed the user guide on conserving the battery, and this has worked for me.

Theres also information on alternative ways to extend the battery life whilst using the 2800 on the road.
