Luna 4X Operating Instructions

7. USE IN AIR
The video light can also be used outside water but at low power level only. If the light gets too hot, it
slowly and automatically reduces the power to avoid overheating.
8. HOW TO OPEN THE CASING
Remove excess water from the outside before opening. Point the light slightly upward while opening
to avoid water from entering the housing.
Friction of the O-ring seal (and therefore force needed to open the cap) increases over storage time.
After long and deep dives the friction might increase too. To avoid high friction, regularly grease the O-ring.
9. MAINTENANCE
After each use rinse well with fresh water.
Care should be taken to avoid scratching of the O-ring seals. Keep seals clean of sand, hair, cloth
fibers or similar materials at all times. O-rings of the battery screw cap should be regularly inspected
and cleaned. Occasionally apply small amounts of silicone grease for lubrication. If not treated, the
O-ring will fail to provide proper sealing causing the light to malfunction.
•
Do not use sharp tools to remove the O-ring.
•
Never use a battery which appears damaged.
•
In case of a damaged lamp, contact your nearest KELDAN dealer.
•
Do not remove front glass cover (high operating voltage).
•
O-rings need to be replaced by KELDAN or an authorized dealer every 5 years.
10. STORAGE AND TRANSPORTATION
Battery and casing must be stored apart in a cool and dry place. Maintain battery pack according to
our recommendations. Separate battery pack from casing if traveling by air.
11. WARRANTY

or as incurred by a third person.
