temporarily. Battery performance is 
particularly limited in temperatures well 
below freezing.

Do not dispose of batteries in a fire as 
they may explode. Dispose of batteries 
according to local regulations. Please 
recycle when possible. Do not dispose as 
household waste.

Never use any charger that is damaged.

Operating times are estimates only. 
Actual performance depends on many 
factors such as device settings selected, 
device features being used (or running in 
the background), battery condition and 
ambient temperature.

Your device is a product of superior 
design and craftsmanship and should be 
treated with care. The following 
suggestions will help you protect your 
warranty coverage.

• 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 high or cold 

temperature. High temperatures can 
shorten the life of electronic devices, 
damage batteries, and warp or melt 
certain plastics. When the device 
warms to its normal temperature 
from a cold temperature, moisture 
can form inside the device and 
damage electronic circuit boards.

• Do not attempt to open the device.
