The Preliminary Leak Test The Preliminary Leak Test
Before placing the camera in the case, latch the case and immerse it in
water to check for leaks as described below.
D Important!
Before placing the camera in the case, be sure that the camera is functioning normally and
that the case does not leak. Failure to check for leaks before use could result in irreparable
damage to the camera. Note that leaks may result if the case is cracked or damaged. Check
the case for cracking and other damage before use, and consult with a Nikon-authorized
service representative in the event that any cracking or damage is found.
1 Latch and immerse the case.
Latch the case and then slowly immerse it in
water, stopping if air is expelled from inside
the case. Keep the case immersed for 2 or 3
seconds and check for bubbles escaping. Test
the case in a shallow area at a depth of about
1 m (3 ft) or in a tub or bucket. Do not use
hot water, as this could exceed the operating
temperature range of 0–40 °C (32–104 °F).
2 Test the controls.
Immerse the case and operate the controls
underwater for 2 to 3 minutes, checking
whether bubbles escape.
3 Check for water inside the case.
Take the case out of the water and dry it thor-
oughly with a soft, dry cloth, then open the
case and check for water. If water has entered
the case, check the O-ring (
0
15, 22–23). If the
cause of the leak can not be determined, take
the case to a Nikon-authorized service repre-
sentative.
