• The storage of a fully discharged battery may cause permanent damage to the battery.

5� BATTERY PROTECTION CIRCUIT

The integrated protection circuit protects the battery from overload, overcharge and deep discharge.

6� CHARGE LEVEL INDICATOR

The charge level monitor circuit shows the available energy by taking into 

account charge and discharge currents. 
The two digit numerical display shows the remaining run time in minutes at 

the actual power setting. 
During charge it shows the remaining charge time (1 digit = 10 minutes). 
The display is turned off when the battery is fully charged.

 

The LED bar with the green LED is a relative display which tells you the 

actual charge level like a fuel gauge.

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, 

the over temperature protection will be activated and the power will be reduced automatically 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. Do not allow water to dry on glass to avoid water marks 

especially  when diving in high mineral content brackish water. Rinse the black magnetic switch ring by 

rotating 3-5 times to dislodge salt or sand on inner portion.
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).
