1. BEFORE USING THE SCALE
To enable you to use this scale correctly, we suggest you read this manual carefully:
1. Do not use scale in areas with excessive water and don’t spray the scale or indicator with water when
cleaning. Erase all water from the scale and indicator with clean dry duster cloth.
2. Load placed on platter must not exceed the maximum weighing capacity of the scale.
3. Keep the scale away from high temperature and damp conditions.
4. If the scale is not going to be used for some time, please clean and store it in plastic bag under dry
condition. A desiccant sachet is suggest to be included to prevent moisture build up. In condition, the
internal rechargeable batteru should be recharged very three months.
5. Before using the scale after a long period of storage, please ensure that the internal battery is fully
charged.
Note: care should be taken not to leave the internal battery on charge for too long, as this may decrease
life of battery.
2. PREPARING TO USE THE SCALE
1. Put the scale on a firm level surface from vibrations for accurate weight readings.
2. Adjust the four leveling feet to the level of scale platform.
3. Avoid operating the scale in direct sunlight or drafts of any kind.
4. Take away any weight that might be on the platform before the scale switched on.
5. Once the scale has been switched on, it will go through a LCD display test and then re-zero to be
ready for use.
6. Please note when displays on the screen, the rechargeable battery needs to be charged.
7. All goods weighed should be placed in the centre of platform for accurate weighing. The footprint of
goods being weighed should not overstep the edges of platform.
