Safety Recommendations
When using the weighing equipment in surroundings with increased safety
requirements, the corresponding regulations must be observed.
The weighing scale may only be used with the power adapter supplied.
Before connecting the power adapter to the scale, the user must ensure that the

If not, please contact Customer Service at the address above.
If the power adapter or its cable is damaged, the weighing scale must immediately be
disconnected from the electricity supply (pull out the power adapter).
If there should be any reason to believe that it is no longer safe to operate the scale, it
should be immediately unplugged from the electricity supply (pull out power adapter)
and secured against inadvertent operation.
In carrying out maintenance work, it is essential to follow the recommendations in
maintenance and service.
The weighing scale must not be operated in an area subject to explosion risks.
Care must be taken when weighing liquids to ensure that no liquid is spilled into the
inside of the scale, into connections on the rear of the equipment or the power adapter.
If liquid is spilled on the scale, it must immediately be unplugged from the main
electricity supply.
The weighing machine may only be operated again after it has inspected by a service
technician.
These operating instructions should read by each user and should be easily accessible
