Maintenance

• Keep it dry. Precipitation, humidity and liquid that
contains minerals will corrode electronic circuits.
• Do not use or store it in dusty, dirty areas as its
detachable parts may be damaged.
• Do not store it in hot areas. High temperatures can
shorten the life of electronic devices, damage batteries,
and melt certain plastics.
• Do not store it in cold areas. When the device warms up,
moisture can form inside it, which may damage
electronic circuit boards.
• Do not attempt to take the device apart. Improper
handling may damage the device.
• Do not drop, knock or shake it. Improper handling may
cause damage to the liquid crystal panel.
• Do not use harsh chemicals, cleaning solvents, or
strong detergents to clean the device.
• Do not paint it. Paint can clog the device's detachable
parts and cause it to malfunction.
• Do not operate the device below the temperature 0 or
over 40 degrees. Excessive heat or cold will cause
malfunction and incur damage to the device. To avoid
such from happening, please do not use the device for
two hours after it has been exposed to excess heat or
cold, because the humidity or moisture formed by the
temperature changing will cause damage to the device.
