1.2 Warnings
l
Avoid lengthy exposure to extreme heat or cold. Your scale works best when
operated at normal room temperature. Always allow the scale to acclimate to
a normal room temperature before use.
l
Allow sufficient warm up time. Turn the scale on and wait for a few minutes if
possible. This will give the internal components a chance to stabilize before
weighing.
l
These electronic scales are precision instruments. Do not operate near an
in-use cell phone, radio, computer or other electronic device. These devices
emit RF and can cause unstable scale readings. If your scale ever performs
poorly, try moving the scale to a different room or location.
l
Avoid using in heavy vibration and airflow conditions.
l
Read the weight reading in short time after loading. The output signature of
load cell and electronic circuit may be little influenced after weighing for a
long time.
1.3 Routine Maintenance
Always turn off the machine and isolate from the power supply before starting any
routine maintenance to avoid the possibility of electric shock.
1.4 Sharp Objects
Do not use sharp objects such as screwdrivers or long fingernails to operate the keys.
1.5 Cleaning the Indicator

and calibration.
