■Use a dry soft cloth such as the one for
cleaning glasses to clean the equipment.
The screen of the FOMA phone sometimes has a
special coating so that they are easier to see. If you
rub it roughly with a dry cloth, it might be scratched.
Take care of the way of handling, and use only a dry,
soft cloth such as the one for cleaning glasses. If the
screen is left with water drop or stain adhered, smear
may be generated or the coating might peel off.
Do not use alcohol, thinner, benzene, detergent or
other solvents for cleaning, otherwise the printing
may be removed or discoloration may result.
■Occasionally clean the terminals of the
equipment using a dry cotton swab.
If the terminals become soiled, the connection might
deteriorate so that the power turns off or the battery
does not charge fully. Wipe the terminals with a dry
cloth or cotton swab.
■Do not place the FOMA phone near an air
conditioner outlets.
Condensation may form due to rapid changes in
temperature, and this may corrode internal parts and
cause malfunction.

phone and battery pack.
If you put the FOMA phone in a bag along with many
other articles or sit with the FOMA phone in a clothes
pocket, the display, internal circuitry and the battery
pack could be damaged or malfunction. Also, if your
FOMA phone is left with an external device connected
to the connector terminal or Earphone/Microphone/AV
