PRECAUTIONS
1. Avoid exposingthe scale to high temperatures anddamp conditions.
2. Keep the scale clean and avoid insects from enteringthe scale.
3. Avoid heavyobjects impactingwith the scale.
4. The load placed on the weigh pan must not exceedthe maximum weighingcapacityof the scale.
5. If the scale is not to be used for an extended periodof time it is recommended that the scale is
cleaned and stored in a plastic bagin dryconditions. A desiccant maybe included.
6. Remove the plastic drip cover from the scale for best weighingaccuracy.
7. We welcome anycomments or suggestions that you mayhave about this product. Please contact
your dealer.
PREPARINGTOUSE THE SCALE Ⅱ
1. Locate the scale on a firm level surface free fromvibrations for accurate weight readings.
2. Adjust the four feet underneath the scale to ensure the bubble level”is in the centre position.
3. Do not place the scale where the temperature changes dramaticallyor in a location where draft can
affect the weighing. Example: Do not expose the scale directlyto sunlight or air-conditioningunits.
4. If possible connect the scale to an electric socket separate from other appliances to avoid
interference.
5. Do not leave anythingonthe scale when it is not in use or when switchingit on.
6. Please locate thegoods in the centre of the weighpan. It will ensure best accuracyof the weight.
7. It is recommended that the scale is warmed up for15-20 minutes before use.
8. Recharge the internal battery, as appropriate, when low batterysymbol is displayed. .
9. The overall dimensions of the goods beingweighed should not exceed the dimension of the weigh
pan.
