Closing the Housing
1.Place housing face down in your lap.
2.Check to see that there is an o'ring on the housing back and that it is clean and in its proper location.
3.Guide the back onto the housing. The o'ring should touch the housing all the way around. There should be an even gap all the way around between the housing and the housing back.
4.Lift the lid snaps so they are extended and place the lid snap into the hook on the housing back.
5.To close the housing push down on the lid snaps until they snap into place . Lid snaps on opposite sides of the housing should be closed at the same time. Be sure they are down far enough to engage the lock.
Double check - Once the housing is
closed, check the o'ring seal. Check the gap between the housing back and the housing, it should be even all the way around.
Look through the clear plastic back at the o'ring. You should see a darkened area where the o'ring is compressed against the housing back. If you do not see an even black compression seal all the way around the back, open the lid snaps, reseat the housing back and close the lid snaps. Visually check the seal again.
