BT77 / BT-77 no gps fix solution

[ipaq3870]

I recently bought a BT77 but it would not obtain GPS lock. I tried the normally suggested solutions of leaving the battery out overnight, fully charging the battery, leaving it outside for several hours, etc., etc. None of these solutions worked.

However, the following resolved the issue:-

1. Remove the battery from the BT77;
2. Remove the two small philips head screws from the bottom of the case;
3. Remove the front of the case. There are two small clips at the top, so pull the case updwards and forwards - gently!
4. You should see a small cell battery - possible covered by a coloured (mine was blue) circular label.
5. Remove the label and the battery. The battery is a tight fit and you may need to lever the plastic clip out of the way to remove it. Be gentle - the mechanical integrity of the battery holder is, shall we say, "adequate".
6. With the cell battery out, go away and make a brew. Survey the wonder that is modern day electronics.
7. Suitably refreshed, put the battery back (and the label back on) and reassemble the unit (if you've got this far it should be a doddle).
8. Powering the unit on should result in a fix after a few minutes.

To confirm (the instructions don't make this clear) - The RED LED will flash if the unit obtains a satellite fix.

Hope that helps,

Steve.
