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 CONTROL RING
Attention, the black ring controls the operating mode of the light with a magnetic eld. Do not place
your compass close to the black control ring (keep a minimum distance of 10cm or 4”).
2� OPERATING MODES
Normal Mode : LOW …� HIGH
- 9 logarithmic Power Levels
Remote Control Mode: “R”
- This is the Mode to control the XR light with the RC1 Remote Control
Basic Workow to connect XR Light(s) to the RC1 Remote Control:
1. Switch the RC1 remote control to PAIR mode.
2. Switch the Video 18XR light to remote mode “R”, now pairing
is possible during the next 10 seconds.
3. Turn the brightness knob on the RC1 remote control. (Use
the channel you want the light to be paired to).
4. The light conrms a successful pairing with short ashes.
3� 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.
Important: If the battery state of health falls below 75%, always use
the included 12.6V to 12.45V adapter cable when charging.
4� 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.

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 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.
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 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.

10� 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.
11� 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.
12� WARRANTY
The light carries a two-year warranty after purchase (proof 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.
13� LIABILITY
KELDAN®declines all responsibility for damages arising from any improper use of the VIDEO 18XR
35000lm CRI 86 light or as incurred by a third person.
The VIDEO 18XR 35000lm CRI 86 light produces an extremely
powerful and intense light�
• Never point directly at a person at close distance.
• Never stare directly into the light.
SAFETY INSTRUCTIONS
CAUTION. Possibly hazardous
