10. Battery information
Your device is powered by a rechargeable battery. The full
performance of a new battery is achieved only after two or three
complete charge and discharge cycles. The battery can be charged
and discharged hundreds of times, but it will eventually wear out.
Unplug the charger from the electrical plug and the device when not
in use. Do not leave a fully charged battery connected to a charger,
since overcharging may shorten its lifetime. If left unused, a fully
charged battery will lose its charge over time.

10
Leaving the device in hot or cold places, such as in a closed car in
summer or winter conditions, will reduce the capacity and lifetime of
the battery. Always try to keep the battery between 15℃ and 25℃
(59℉ and 77℉). A device with a hot or cold battery may not work
temporarily, even when the battery is fully charged. Battery
performance is particularly limited in temperatures well below
freezing.
Do not dispose of batteries in a fire as they may explode. Batteries
may also explode if damaged. Dispose of batteries according to local
regulations. Please recycle when possible. Do not dispose as
household waste.
11 Care and maintenance
Your device is a product of superior design and craftsmanship and
should be treated with care. The suggestions below will help you
protect your warranty coverage.
· Keep all accessories and enhancements out of the reach of small
children.
· Keep the device dry. Precipitation, humidity, and all types of
liquids or moisture can contain minerals that will corrode electronic
circuits. If your device does get wet, allow it to dry completely.
· Do not use or store the device in dusty, dirty areas. Its moving
parts and electronic components can be damaged.
· Do not store the device in hot areas. High temperatures can

11
shorten the life of electronic devices, damage batteries, and warp or
melt certain plastics.
· Do not store the device in cold areas. When the device returns to
its normal temperature, moisture can form inside the device and
damage electronic circuit boards.
· Do not drop, knock, or shake the device. Rough handling can
break internal circuit boards and fine mechanics.
· Do not use harsh chemicals, cleaning solvents, or strong
detergents to clean the device.
· Do not paint the device. Paint can clog the moving parts and
prevent proper operation.
All of the above suggestions apply equally to your device, battery,
charger, or any enhancement. If any device is not working properly,
take it to the nearest authorized service facility.
