●
Do not apply excessive force to the product during use. Be sure not to put the product into a tightly packed bag or place
a heavy object on the product in a bag. Sitting on the product in your pocket might damage the display panel or internal
circuit board resulting in a malfunction.
If a cable is connected to the external connection terminal in such a condition, the connector might be damaged resulting in
a malfunction. Such damage and malfunction are not covered by the warranty, even if there is no external damage.
●
Do not use the product in extremely hot, cold or humid places. (Use within an ambient temperature range of 5
℃
to 35
℃
and humidity range of 35% to 85%)
●
Do not use in places subject to lots of dust or vibration. Doing so might cause a malfunction.
●
Clean the external connection terminal with dry cotton swabs, etc. every now and then. Soiled terminals might cause poor
connection. Do not exert a strong force to clean the external connection terminal to prevent deformation.
●
Clean the product with a soft dry cloth (such as used for cleaning eyeglasses). Forceful rubbing with a dry cloth may
scratch the display panel. The display panel may become stained if water or dirt is kept on the surface. Wiping the product
using alcohol, thinner, benzene, detergent, glass cleaner, etc. might erase the printing on the outer casing resulting in a
malfunction.
●
Use as far away as possible from land-line phones, TVs and radios. Use nearby might affect them.
●
The product might become warm while charging, etc. depending on the situation, but this is not abnormal.
●
Do not place near corrosive chemicals or in places where corrosive gas is generated. Doing so might cause a malfunction.
●
Do not use outside when you can hear thunder. Doing so might risk lightning strikes and electric shock.
●
Be sure to use only specified charging equipment. Use of other charging equipment might cause a malfunction.
●
Do not put the product in a cooking apparatus such as microwave oven or a pressure vessel. Doing so might cause a
malfunction.
