Notes on Use
______________________________________________________________
CAUTION The unit should always be operated in a range from -20
to 70 and 80% RH or less. During data transfer when
connected to personal computer (using RS-232C),
operating temperature range is from 0 to 40 .
If used outside the specified environmental ranges for
operation (or storage), the operation of the unit cannot be
guaranteed.
This product is not designed to be entirely water- or dust-
proof. To avoid damage, do not use it in a wet or dusty
environment.
Take care to avoid condensation. In particular, if there is a
sudden change of temperature (for example moving from a
cold place to a warm one), condensation is likely to occur.
Do not use the product where it may be exposed to
corrosive or combustible gases. The product may be
damaged or cause an explosion.
To avoid corrosion from battery leakage, remove the
batteries from the product if it is to be stored for a long
time.
Leaving the unit connected to an activated personal
computer hastens battery discharge.
When not using the unit, disconnect it from personal
computer.
