1.1. General and Safety Information
Introduction
For use in dry environments only.
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 3 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 60 days to avoid premature performance
degradation. 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.

Battery and Charging
Power is supplied by an internal rechargeable 6V 4Ah rechargeable battery. When “Lo.bAt” is displayed, the battery must be
recharged. Plug in the AC power adapter to recharge the battery. The scale may continue to be used on AC power during
charging. Full charging time is approximately 10-12 hours.
Battery life and recharge time will vary with use. Over time, the operating time per each full charge will degrade. If the
operating time is no longer acceptable, the battery must be replaced. When storing the scale for extended periods, the battery
must be charged every 90 days to avoid premature performance degradation.
