METALSUB kl1242 Cable Light

IMPORTANT SAFETY PRECAUTIONS
- A. Read this manual carefully before using the dive light.
- B. When you are diving in situations where your life can depend on having sufficient light (for instance in caves or on wrecks), make sure you always take a back-up light with you.
- C. Prior to air travel, disconnect the Cable Light from the battery pack, to prevent overheating in case the light switches on due to accidental impact or mishandling.
- D. To prevent short-circuiting, it is essential to only connect the light head with the battery pack using the supplied Metalsub tank plug(s).
- E. Always use the supplied charger.
- F. Charg the battery pack:
- always in a dry and well ventilated place
- in an ambiant temperature between 0 and 30°C
- never close to open fire
- G. Never shine the light directly into someone’s eyes, as this can cause eye damage.
HOW TO USE THE DIVE LIGHT
General
-
After each dive, soak the lamp in clean fresh water for a few minutes. Leave the light head connected to the battery pack while rinsing it to avoid exposing the contacts
of the battery and cable to water. -
Avoid exposing the contacts of the cable or battery pack to water, as this may damage or cause short-circuiting of the battery tank.
-
Rinse the dive light under running water to remove all traces of sand and salt.
-
Avoid physical impact.
-
Avoid overheating and direct exposure to sunlight.
-
To make sure the light doesn’t overheat or cause burn damage to objects in its immediate vicinity, it is strongly advised to use it only while submerged under water.
-
Never disconnect the light from the battery pack underwater.
-
Never store the battery pack uncharged for a long period.
-
Always use the charger that is delivered with the dive light.
Charging the battery pack
The charger is suitable for power outlets with a voltage between 100 and
240 Vac. The battery pack is delivered uncharged, so it is important to charge
the battery pack completely with a full charge cycle. Make sure that the
connector is clean and dry. Securely plug the charge connector into the
battery tank. The charger is fitted with a Delta-V charge controller and safety
timer. The charge controller switches to pulse charging as soon as the battery
reaches its full power. Please wait until the small light (LED) on the charger
lights green continuously before you disconnect the charger from the battery
pack. While charging the indication LED on the charger lights red
continuously. The battery pack fully charged and using trickle charge when the
indication LED on the charger lights green continuously.
Warning: ALWAYS USE THE CHARGER THAT IS DELIVERED WITH THE DIVE LIGHT!
THE USE OF OTHER CHARGERS CAN DAMAGE THE BATTERY CELLS INSIDE!
Deep discharge protection
When the battery is almost empty (only 0,9 V per cel remaining) the deep
discharge protection circuit will switch off the light. This prevents damage of
the battery cells.
Warning:
If you don’t use the torch for a long time we advise you to disconnect the
cable light from the battery pack to prevent fully discharging the battery
pack, because the light head wil use a tiny amount of power continuously for
its electronic switching circuit. Never store the battery pack uncharged for a
long period. If the battery pack is not used for a long period, we advise you
first to charge the battery pack completely. The battery pack can loose up to
15% of its charge per month. Subsequently discharge and recharge the battery
pack completely every three months. When the battery has been stored uncharged
for a long period, it can lose its charge entirely. This can cause irreparable
damage to the battery cells.
Connecting the light head to the battery tank
- Connecting the light head to the battery pack is done by placing the special watertight connector in the counter connector socket on the battery pack. The connection is made with a little inward push followed by a quarter turn to the right. Disconnecting is done by performing the same sequence in reverse.
- Make sure that the connectors are completely clean and dry. When necessary, clean the O-ring and use a little bit of silicone grease to create a perfect water tight seal.
- Never use a sharp object to remove the O-ring. This could damage the O-ring groove which might cause leakage over time.
- Warning: Never disconnect the light from the battery pack underwater! This will damage the connector inside the battery pack!
Switching the cable light on and off
The Light has two switch rings; The switch ring located at the rear site is
for controlling the spot light power. The front switch ring is for controlling
the flood light power.
The Light is switched on by sliding the locking clip at the switch ring
backwards and then turning the ring to the right 45°(position 1) = dim
position, or 90° (position 2) = 100%Light power. To lock the switch ring(s),
slide the locking clip backward and rotate the switch ring fully to the left
until it clicks (locks) into the locked position; the light will turn off.
- The lamp is for underwater use only. When using it above water, the lamp might become overheated and shut down. After cooling down the lamp will reset itself and work normally again.
Signal option
Beacon flash:| turn the one of the switches within 1 second from
position 2 to position 1 and back to position 2.
---|---
Strobe flash:| turn the switch for a second time within 1 second from
position 2 to position 1 and back to position 2.
S.O.S. flash:| turn the switch for a third time within 1 second from
position 2 to position 1 and back to position 2.
From Beacon flash to Strobe:| when in Beacon flash position, turn the switch
within 1 second from position 2 to position 1 and back to position 2.
From Strobe to S.O.S.:| when in strobe flash position, turn the switch within
1 second from position 2 to position 1 and back to position 2.
Exit from any signal option:| turn off the signals to turn the switch to
position 1 for more than 1 second.
The LED indicator on the light head
The LED indicator on the back of the light head supplies the following
information:
- LED green: 100% – 50% remain capacity
- LED orange: 50% – 20% remain capacity
- LED red: 20% – 10% remain capacity
- LED red blinking: 10% – 0% remain capacity
Note: These values are guiding values only and depend very much on water temperatures and the type of battery tank used! The values shown above were measured at a water temperature of 20°Celsius. In colder water (for instance 10°Celsius or less) the LED light will go from green to orange in just a few minutes. This doesn’t mean the capacity of the battery tank is decreased to 50%, though the battery tank capicity reduces slightly in cold temperatures <10°C.
Disconnecting the light head
Turn the cable connector a quarter turn to the left (anti clockwise) and
pull it straight out of the battery pack connector. Before reassembly inspect
and clean the O-rings, or replace the O-rings when damaged or deformed and
apply a thin layer of silicone grease. Insert the connector fully into the
battery pack connector and turn it a quarter turn to the right (clockwise),
until it locks firmly into place.
Connection of the battery tank PR1204 / PR1211 / PR1215 onto the scuba tank
or BCD
First connect the tank plate onto the scuba tank or tank belt of the BCD.
You can use two methods:
- For a permanent connection attach the tank plate with stainless steel damps to the scuba tank.
- Connect the tank plate to the tank belt of your BCD by guiding the belt through the slots in the tank plate (see figure). Subsequently fit the BCD tank belt with the attached tank plate onto the scuba tank. Now you can connect the battery pack onto the tank plate by depressing the locating button, pushing the battery pack down onto the locating part of the tank plate, next onto te securing port and then releasing the locating button.

Connection of the battery tank FX1204 / FX1209 onto the scuba tank
Slide the bracket of the battery tank over the belt of the BCD. Close the belt
securely.
