SAFETY PRECAUTIONS
△WARNING
Important information to alert you to a situation
that might cause serious injury and damage to
your balance if instructions are not followed.
△CAUTION
Important information that tells how to prevent
damage to equipment.
All safety messages are identified by the following the words "WARNING" and
"CAUTION". These words mean the following:
When using the scale/balance, the following safety precautions should always
be followed.
△ WARNING
Use only the AC adaptor supplied with the scale/balance. Other adaptor
may cause damage.
△ CAUTION
Avoid using the balance under direct sun light. This may cause discoloration or
malfunctions. Do not use scales onto the carpet base, it may cause scales
inaccurate and need re-calibration.
Do not mix batteries. Replace all other batteries at the same time. Do not
replace only a portion of the 6 batteries as this may cause a malfunction. If the
scale is not to be used for a long period of time, remove all batteries from the
battery compartment to avoid leakage, which may cause damage to this scale.
Avoid overloading the scale, as this may cause permanent damage and void
your warranty – do not EVER exceed the maximum capacity of the scale.
Keep the scale away from water – this scale is not water resistant. Shock, injury
and electrical damage can occur if used in a wet location!
