Notes on Usage
• Do not use in places subject to lots of dust or
vibration. Doing so may cause malfunction.
• Clean the connection terminals with dry cotton
swabs, etc. every now and then. Soiled terminals
might cause poor connection. Do not exert a strong
force to clean the connection terminals to prevent
deformation.
• Clean the product with a soft dry cloth (such as the
type used for eyeglasses). Forcefully rubbing with a
dry cloth may scratch the display. The display may
be stained if splash or smear is left attached to the
surface. Wiping the product using alcohol, thinner,
benzine, detergent, glass cleaner, etc. might
erase the printing on the outer casing or cause
discoloration.

TVs and radios. Using the product near these
devices may affect them.

Doing so might risk lightning strikes and electric
shock.
• Be sure to use only the specified peripheral devices.
Using peripheral devices other than those specified
may cause malfunction.
• Do not put the product in a cooking apparatus such
as microwave oven or a high-pressure vessel. Doing
so may cause malfunction.

terminal or headset connection terminal. Do not
allow conductive foreign objects (metal fragments,
