The 302 manual makes no mention of an internal battery, so I assume
there is no need to change it. I don't know how they handle trashing the
security seal if the box is opened.

Same explanation for a 302 would be appreciated.

Sounds easy enough. One question though - wouldn't you now have a
"security
invalid" message for all traces? Not that it matters for
non-record/badge
work, but...

No, the GPS-NAV is designed such that you can replace the battery without
breaking the security seal. That is why power must be applied, the
contents of the security memory are then maintained by the external power
source. If no external power is connected when the battery is removed,
the contents of the security memory will be lost, and the electronic seal
will be broken.
