PRECAUTIONS
Do not disassemble the scale.
When any damage or
defect occurs, contact
your CAS authorized
dealer immediately for
proper repair.
Do not overload beyond the maximum
weight limit.
Do not pull the plug by its cord when
unplugging. Damaged cord could cause
electric shock or fire.
Avoid placing the scale near heater
or in direct sunlight.
Scale must be grounded to minimize
electricity static. This will minimize
defect or electric shock.
Use proper Adapter. Incorrect adapter
could damage the scale. Insert plug firmly to wall outlet to
prevent electric shock.
To reduce electric shock or incorrect
reading, Do not spill water on the scale
or place it in humid condition.
Warning
To prevent from fire occurring, Do not
place or use the scale near
flammable or corrosive
gas.
For consistent and accurate reading,
maintain periodical check by your
CAS authorized dealer.
Avoid sudden shock to the scale.
Internal mechanism could be damaged.
Place the scale on firm and temperature
consistent environment.
Attention
Keep the scale away from other
electromagnetic generating devices.
This may interfere with accurate
reading.
Take the battery out when scale is not in
use for long time. Leakage from the
batteries is hazardous.
