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 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, remove the battery, and allow the device to dry
completely before replacing it.
• 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 attempt to open the device other than as
instructed in this guide.
• 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.
