followed. WARNING
Only use the correct AC adapter with the scale. Other adaptors may
cause permanent electrical damage.
CAUTION
- Avoid placing the scale in direct sunlight, this may cause discoloration or
malfunction.
- Replace all batteries at the same time – Do not replace only a portion of the
6 batteries as this may cause malfunction.
- If the scale is not to be used for a long period of time, remove all batteries
from the battery compartment to avoid leakage, which may cause damage to
the scale.
-Avoid overloading the scale, as this may cause permanent damage and
avoid your warranty – do not EVER exceed the maximum capacity of
the scale.
- Keep the scale away from water – this scale is not water resistant. Shock,
injury and electrical damage can occur if used in a wet location!
- Matter charged with static electricity could affect accuracy. Discharge all
static electricity. For example, one method is to use Static-Guard spray, and
spray it on both sides of the weighing platform.

CALIBRATION
When to calibrate?
Calibration may be required when it is initially installed, if the scale is
moved to a substantial distance.
This is necessary because the weight of a mass in one location is not
necessarily the same in another location. Also, with time and use, mechanical
deviations may occur.

and insert four batteries (R6P/LR6/AAA
size) into the battery compartment,
taking extreme care that the polarities
plus and minus is observed.
Plug the Ac adapter to the AC adapter
socket on the side. The AC input
requirement could be 110,120,220,230
