MDI-20

Thank you for purchasing the American Weigh MDI-20 baby scale. Please read all operating instructions carefully before use. Scales are precision measuring devices and should always be handled with proper care. To ensure years of reliable service, keep these simple tips in mind:

• Do not exceed the scale's maximum capacity. Overloading your scale can permanently damage it!
• Avoid exposure to extreme heat or cold. Scales perform best at normal room temperature. If temperatures have changed dramatically, calibration and adjustment may be necessary.
• Allow your scale to warm up for 30-60 seconds before performing calibration and adjustment(if available).
• Store your scale in a clean, dry location. Dust, dirt, and moisture can accumulate on the weighing sensors and electronics causing inaccuracy or malfunction.
• Avoid using your scale in close proximity to strong radio wave emitting devices such as computers, cash registers, and cordless phones.
  • Always weigh on a flat and level surface, free from vibrations and drafts. The corner of a room is usually the most stable.
  • Gently apply all items to be weighed. Do not drop items onto the weighing platform.
• Avoid dropping your scale. The warranty does not cover damage due to rough treatment or overload.
• Check the batteries first if you are having any trouble with your scale. This simple step can remedy most scale issues.
  • Do not disassemble your scale. This product contains no
