INSTRUCTION FOR USE
Thank you for purchasing the 9903 Dolphin II weighing scale of Excell. To enable you to use this
scale correctly, we suggest that you read the following instructions carefully.
1. Don’t bump the scale against other items nor load it with heavy weight exceeding its full
capacity.
2. Keep it away from high temperature.
3. If the scale is not going to be used for a certain period of time, clean it and store it in a
polythene bag. A desiccant may be included.
4. If the scale is not used for a long period of time, recharge it every 3 months so as to ensure a
long life of the battery. Fully recharge it before using again. Take care not to keep the scale
being charged for too long.

exceed the dimension of the platter.
PREPARING TO USE THE SCALE
1. Please locate the scale on a stable, level surface to ensure accurate weight readings.
2. Adjust the four leveling feet to make the balance horizontal. Make sure that the level bubble is
in the center of the circle.
3. Keep the scale away from places with strong drafts or excessive temperature fluctuations (e.g.
direct sunlight or the air louver of an air conditioner).
4. There should be no weight on the scale when the scale is switched on.
5. Once the scale is switched on, it will go through a LCD display test and then re-zero to be
ready for use.
6. Please warm up the scale for 15~20 minutes before operation.
7. Please note when the symbol flashes on the screen, the battery needs to be
recharged.
