FLASH GUN CARE AND MAINTAINANCE
All parts of the flash gun are made of anodized, salt water-resistant aluminum or synthetic
materials. Nevertheless, it is advisable to rinse the appliance in fresh water after using it in
salt water. This applies in particular to the control panel. Do not remove the synchronous
cable until after you have cleaned your camera with fresh water.

NEVER IMMERSE THE FLASH GUN INTO WATER WITHOUT THE CAP ON THE
SYNCHRONOUS PLUG
.
REPLACING THE O-RINGS AND ACCUMULATOR
We recommend that you return the flash gun to subtronic for replacement of all the O-rings
and the accumulator after four to five years of use. You can check and replace the O-rings
on the NIKONOS plug connector yourself.
The connector thread and O-ring should be
kept lightly lubricated.
CHECKING THE CABLES
All the spiral cables are resistant to salt water and do not need any special care. However,
you should check all the cables for cuts or cracks, especially after traveling by air. This is
necessary to prevent water from seeping into the cables, and possibly into the camera and
the flash gun.
 Always pack the flash gun together with all the detached cables.
Water may contaminate the contacts if you do not insert the plug connectors into the body
of the camera or flash gun properly. The sockets are sealed facing inwards, so that water is
not able to infiltrate into the flash gun even if the cable is not attached correctly.
Make sure that you always loosen the plug connector lock nut when inserting the
connector. Do not tighten it again until you have securely screwed in the plug connector
with the lock nut lying flat on the bottom of the camera. Ensure that the camera rail does
not prevent it from sitting securely. Not only could this damage the camera, but water could
also seep into cables when diving in deep water. The plug connectors will corrode over
time, preventing the flash gun from operating or being charged.
Traces of salt water on the contacts may also cause the flash gun to be triggered
incorrectly. If the flash gun fires when switching it on, the plug connection is almost always
the cause of the problem.
•
You should therefore always check to make sure that the plug connector with the O-
ring is connected securely every time before you go diving.
•
Make sure that the housing and flash guns do not exert pressure on the cable
connectors when you put them down!
•
Cable breakages are usually caused by excessive tension. Make sure that the cables
do not get tangled while diving.
•
When unscrewing or screwing the caps, make sure that you hold the synchronized
cable by the plug connector and not by the cable itself. Otherwise, the cable could
become twisted at the plug connection and cause a cable breakage.
