Maintenance Tips
The bulkhead I/O connector port
The bulkhead I/O connector port is watertight and any water that gets in to the port
cannot harm your VR. However, should sea water get inside the port or the ends of
your cable link, flush them with fresh water as soon as possible afterwards then leave
them to dry completely BEFORE refitting the cap. If the reading from a oxygen cell
cable becomes erratic, a solution may be to put a SMALL amount of grease on the
metal end of the cable end that slides into the bulkhead I/O connector to lubricate the
inner O ring of the bulkhead connector. This will serve to improve the seal and make
the connection more reliable. If corrosion appears on the contacts rinse in a solution of
white vinegar or electrical contact cleaner and use a fine toothbrush to remove the
build-up. Rinse and dry before replacing the cap. Remember, the cleanliness of the
contacts is essential to the integrity of the link. Look after your cable and it will look
after you.
Switch Maintenance
If the switch sticks, rotate it first in its groove to loosen it. If that does not work, hold
the switch in and, with a sm
all flat head screwdriver, carefully ease out the silver
circlips holding it in from the small groove on the back of the VR. The spring and
switch will then come out easily. Soak the switch and spring in white vinegar or
contact cleaner, rinse with fresh water and dry off. Flush the switch groove with fresh
water, spray A LITTLE light engineering oil (WD 40 or similar) inside the hole.
Put the spring and switch back in, push it in and out a few times and it should now
move freely. If so, replace the circlips while holding the switch completely in. Push
the circlips down firmly.
