VIDEO 24X 35000lm CRI82 Operating Instructions 2
BEFORE STARTING
• Read operating instructions.
• Keep O-ring clean and grease regularly.
• For storage charge the battery to 30-60%. Storing a fully charged or empty battery is
detrimental to the battery’s life in the long run.
• Discharge/charge battery at least every 6 months.
• Remove the battery from casing when storing the light.
• Charge the battery before every dive.

1. MAGNETIC SWITCH
Attention: the light uses a magnetic switch, so your compass reading may be off when you hold it close
(within 10cm or 4”) to the black on/off switch..
2. CHARGE OF THE BATTERY
Only use the supplied Li-Ion charger to charge the battery. For best results, the battery should be
charged at room temperature. Avoid charging when batteries are still hot after use. Let them cool down
before charging.
3. MAINTENANCE OF BATTERY
It is not recommended to discharge the battery after each dive. Complete discharge after every use
may reduce life time of battery. We recommend the following service procedures:
• For storage remove battery from casing.
• Discharge and recharge the battery at least once every 6 months.
• Avoid deep discharge of the battery pack.
• Store battery with approximately a 30-60% partial charge in a dry and cool place.
• Charge fully before each dive.
• The storage of a fully discharged battery may cause permanent damage to the battery.
4. BATTERY PROTECTION CIRCUIT
The integrated protection circuit protects the battery from overload, overcharge and deep discharge.
5. CHARGE LEVEL INDICATOR
The charge level monitor circuit shows the available energy by taking into
account charge and discharge currents. The three digit numerical display
shows the remaining run time in minutes at the actual power setting or the
remaining charge time in minutes. The LED bar with the green LED is a
relative display which tells you the actual charge level like a fuel gauge.

6. 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.
7. 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.
8. 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bers
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.
9. TRANSPORT
IMPORTANT: The total capacity of the battery pack exceeds
the maximum capacity for Li-Ion battery allowed on airplanes!
Therefore the battery need to be disassembled for safe transport
on airplanes. After disassembling you can carry safely three single
batterypacks, each one will be below the maximum capacity limit.
The three batteries of a battery tray should always kept together
as a set and should not be mixed with batteries from another
battery tray. This will ensure maximum lifetime of the batteries. If
batteries show degraded capacity and need to be replaced they
should be replaced all three together at once.

10. STORAGE
Store the battery tray outside of the housing of the light in a cool and dry place. Maintain battery pack
according to our recommendations.
11. WARRANTY
The light carries a two-year warranty after purchase (proove of purchase date required). The warranty is
limited to material defects which occur when correctly handling the product. The warranty does not cover
the battery.
KELDAN®warranty coverage is void for defects as a result of improper use.
