1. INTRODUCTION
General and Safety Information
 For use in dry environments only.
 This product uses a Acid battery. Dispose of according to local laws and regulations.
 Read and understand all operating instructions before using this product.Keep this manual for
future reference.
 Allow sufficient warm up time. Turn the scale on and allow up to 10 minutes for internal components to stabilize
before weighing.
 Record the weight shortly after placing a load on the platter. Leaving loads in place for extended periods may vary the
load cell’s output signature and may result in a less accurate reading.
 Avoid extended exposure to extreme heat or cold. Optimum operation is at normal room temperature. See operating
temperature range in the specifications table. Allow the scale to acclimate to room temperature before using.
 When storing the scale for extended periods, the battery must be charged every 90 days to avoid premature
performance degradation. Over time, the operating time per charge will degrade. If the operating time is no longer
acceptable even after recharging, the battery must be replaced.
 Electronic scales are precision instruments. Do not operate near cell phones, radios, computers or other electronic
devices that emit radio frequencies that may cause unstable readings.
