2. Important Notes for Users
Handling Tips
This scale is a precision instrument utilizing state-of-the art technology. To keep the unit in the best
condition, follow these instructions carefully.
• Do not attempt to disassemble the measuring platform and display.
• Avoid excessive impact or vibration to the unit.
• Place the unit in an area free from direct sunlight, heating equipment, high humidity, or extreme
temperature change.
• Never submerge in water or spill chemical liquids. To clean, use a dampened cloth and mild detergent.
• If the product will not be used for a long period, remove the batteries before storage.
Moving the Scale
The scale has two rear wheels on the back of the platform. To avoid damage, use the wheels when moving
