A couple of points:
1. There is a spare battery, so please swap out and charge the one that you have just used.
2. The photos stored on the card could be deleted at any time (if a big job needs more room on the storage card), so PLEASE download them before you take the camera back to the lab to avoid losing them.
3. The GPS should be turned on only when you need it (and set to OFF when you get on a plane).
