WARNING for Battery:
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 L2S14C. 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
