1. At the first installation, make sure to check the external figure of battery. If there is any spill,
swollen, stink, or unusual found, then do not use the product and contact the dealer. If it’s
normal, then charge the battery fully and use it.
2. The battery is lithium-ion rechargeable one.
3. When transporting only battery, make sure to keep it in soft case. Do not make any
conductor to connect the battery charging point.
4. The battery operating time may shorten using in the cold place (below (-10℃) even fully
charged one. In that case, warm up the battery within the pocket before using L2S15. Do
not heat up the battery with microwave or any heater.
5. Use only the charger which is provided by Xenosys.
6. Charger battery in the range of +10℃~ +35℃. It may take longer to charger the battery out
of this temperature range.
7. Provided battery can be charged and discharged about 300 times at room temperature.
Lithium-ion battery is expendables, thus if the operating time is shortened after full charge,
we recommend exchanging new battery.
8. Be careful on benzene, thinner, alcohol (volatile & flammable fluid) and water. If those
chemicals penetrate the battery, it may cause the trouble in circuit and any accident.
9. If there is any swollen battery, spill, emit, or fire, stop using immediately and contact the
distributor (dealer) or the manufacturer.
10. Never use any damaged battery and charger.
11. In case of the first installation or unused long time, then charge the battery fully before
using.
WARNING for Charger:
1. Do not connect any metallic objects between the cradle connector and battery. This may
cause the defective on the charger and charger cradle.
2. Use only the charger which is provided by Xenosys on the phone jack. This may cause the
defective on the charger and charger cradle.

①Charging Signal LED: Orange –Charging, Green –Finished charging.
②DC5V Connecting Jack: DC5V power supply connecting jack.
③Charging terminals: Assemble the battery pack (BTP15) and connect power supply
to start charging the battery.
WARNING:
- Do not connect any metallic objects to the charging terminal except the battery.
- Charging terminal is weak at external shock, so be careful on assembling the battery pack. If
the charging terminal is broken, it is out of order.
Warning –Do not use non-Xenosys supplied power supply. This will cause severe damage
to the cradle & main body which is also excluded from the under warranty.
6. Power Supply
①Charging plug: To supply the power to DC5V connecting jack.
Warning –Do not use any other device randomly which may cause the defective reason.
In case of using non-Xenosys-supplied charger with higher voltage (over 5V), it will cause the
severe damage to main body. Please check if its Xenosys supplied charger and the serial
number. If it’s Xenosys supplied one, then stop using and contact the distributor (dealer) or
the manufacturer. If not, make sure to use Xenosys DC5V power supply.

OPERATING INSTRUCTION
A. Preparation before usage
1. Check components
Components are shown on page 8~9. They can differ from the picture and replace or
delete with new parts for better performance.
2. Charging battery & Assembling components
The battery is not completely charged, so charge them fully before the first-time usage.
①Connect power supply & charger to supply the power.
②If the battery is fully charged, it will show green light on charger LED.
③Assemble the control unit & fully charged battery, then connect LED lens module wire
to the circular connector of the control unit.
B. Operating Instructions
1. Finish the preparation and put the main body to waist belt or inside of pocket.
2. When using headband, connect LED lens module to headband attachment and adjust to
your head. When using surgical telescope, connect LED lens module to glasses nose
bridge part.
3. Use gown clips to fix the wire and remove the protection cap of LED lens module.
4. Turn on the button of control unit to start the light operating and change the position of
lens module to your own needs
5. Press the intensity change button either control unit or remote controller to match your own
needs of light intensity.
WARNING –On turn-on LED, do not look directly into LED lens module or some one’s
eyes to avoid the risk of permanent eye damage.
C. Maintenance & Storage after use
1. If the usage is done, press the power ON/OFF button to turn off. Then store it to the case
after cleaning dirt or bloods for further use.
Caution –When no-use for long time, make sure to remove the battery from the battery pack.

2. Store LED light in the place free from the air with pressure, temperature, humidity, wind, ray
of light, dirt, salinity, and ion.
3. Store L2S15 in the place free from the declination, shack, and shock.
4. Store L2S15 in the place free from gas, smoke, and chemical fluid.
5. Clean up & wash for next time use.
Caution –External can be cleaned with soft cloth. In case of heavy pollution, try with a bit of
neutral detergent and make sure to NO water or electrolyte flow into the main body.
6. In case of malfunctioning, stop using immediately and contact the dealer.
7. Do not disassemble, repair, or modify the equipment by unauthorized personnel.
Caution- Unauthorized disassemble, repair, or modification are out of warranty.
8. The way to maintain the battery lifespan longer is to exchange fully charged battery before
“beep”sound and the battery alarm sign, and recharge the used battery.
9. Warning for storage of battery pack
As Li-ion battery is small-sized with high power, if it is stored fully charged condition for a
long time, the battery lifespan can be reduced.
(1) Store it under half-charged condition in case of non-use immediately.
(2) Store the battery with separated from the main body in case of long-time no use.
(3) Recommend to keep it in the dry condition with ambient temperature range of 6℃ ~ 40℃.
Keep away from too hot or extremely cold places.
10. Battery Service Life
Provided battery can be charged and discharged about 300 times at room temperature.
Lithium-ion battery is expendables, thus if the operating time is shortened after full charge,
we recommend exchanging new battery.

Intensity Change Button
D. Turn on light & Intensity change
1. Assemble the control unit & battery pack, then press power ON/OFF button to start.
①Check the light comes out from LED lens module.
②Check the battery remaining signal on front of control unit. (It will show with the unit
of % for remaining value)
