US-750EX Instruction Manual

Thank you for purchasing US-750EX digital pocket scale. Please read all operating
instructions carefully before use. Scales are precision instruments and should always be handled with
proper care. To ensure years of reliable service, keep these simple tips in mind:
* Do not exceed the scales 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, recalibration may be necessary.
* Allow your scale to warm up for 30-60 seconds before use.
* 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 cell phones.
* Always weigh on a lat 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.
