stability in operation of the scale, be sure to ground the scale.

Avoid getting the scale wet as it is not water resistant. Any leakage of

liquid into the scale may damage the scale or cause an electric shock to

the user.

Use a power source (voltage, frequency, outlet type)

adapted to the specification of the scale. If excessive voltage

is used, the scale may overheat and be damaged or cause a fire.

Operate the scale on a stable, rigid and flat table.

Handle the scale carefully. It is a precision device,

subjecting it to impact may result in a malfunction.

If the device is not be used for a long period of time, the power

should be turned off and disconnect the power cable.

Do not disassemble, remodel or repair this product or accessories.

Do not weigh items larger than the scale's range, as this may damage

the load cell of the scale.
