Usage in a cold region
Low temperature (10°C or lower) degrades the performance of a battery. The life of the
battery in a cold region may be shorter than the average.
Follow the instructions listed below to efficiently use the battery:
1. When the LED of the battery flashes red, charge or replace the battery pack with a spare.
2. Warm the spare by keeping it in your pocket until ready to mount. When warming the spare
with a body heater, be careful not to directly contact the heater to the battery.
3. A battery pack should be charged at room temperature (between 10° to 30°C).

Efficient battery usage
1. Be careful not to allow any debris (such as sand or dust) into the terminals of the battery. If the
terminals get dirty, clean them with a soft cloth. Then connect the battery to the charger or
mount the battery in the device.
2. Even after being fully charged, the battery naturally will gradually lose power as time passes.
Recharge the battery one or two days before use.
3. Store the battery pack in a cool place. To ensure long life, charge the battery pack at room
temperature (between 10° to 30°C).

Cleaning
1. Covers

diluted mild detergent and firmly squeezed. When using a cloth soaked in a soap-water
solution, squeeze the cloth firmly enough to prevent any water from dripping into the
device. Water may cause a device failure.
Do not use volatile solvents such as thinner and benzene. They cause discoloration and
may erase the characters on the covers.
2. Display
Clean the display with one of the following:
-- a cloth soaked in water and firmly squeezed
-- a fine cloth, such as those used for cleaning eyeglasses
