Temperature extremes may affect the ability of the battery to charge. Always try to keep the
device between 15 °C and 25 °C (59 °F and 77 °F). Leaving the device in hot or cold places
such as in closed car in summer or winter conditions will reduce the capacity and lifetime of
the battery. A device with hot or cold battery may not work for a while even when the battery
is fully charged. Battery performance is particularly limited in temperatures well below
freezing. Do not charge in humid environment.
Care and Maintenance
–
Do not expose the device to liquid, moisture or humidity as it is not waterproof.
–
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 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.
–
