Operation Manual

11
Close and seal the waterproof door. Make sure the O-ring is
perfectly clean and undamaged. Carefully close the waterproof
door to make sure nothing gets trapped near the o-ring and make
sure o-ring slips into position and does not get pinched. Make
sure the waterproof door is completely closed. Lock the latch by
sliding the safety lock upwards.
Important:
Refer to Maintaining a Waterproof Seal in section VII of this manual on
how to inspect the O-ring for cuts, tears, dirt or other damage. Clean or
replace as necessary. Do not grease O-ring. Wipe the O-ring and contact
surfaces with a damp cotton cloth to clean. Never stretch the O-ring.
