SPECIAL NOTICE While installing the load cell, power cord hookup or replacing a new rechargeable battery, the indicator housing must be opened. It must be done by a technician assigned by your electronic indicator provider to avoid affecting the waterproof ability of this indicator. Before opening the housing, make sure the indicator is dry, if there is any liquid on it, please wipe it with a clean cloth. HOW TO INSTALL THE HOUSING After installing the load cell, power cord hookup or replacing a new rechargeable battery, the housing must be screwed by the assigned order as shown below. Screw lightly first, then screw them tight using a 12 kgf-cm torsion. P.s. Please use a torsion-adjustable screw driver. Screwing order: 1 3 6 5 2 4  QWS  GWS  GWS

Intructions for Use 1. The load placed on the weigh pan must NOT exceed the maximum weighing capacity of the scale. 2. Protect the scale from high temperatures. 3. Avoid objects impacting with the scale. Do not drop loads onto the scale or subject the weigh pan to any strong shock loads. 4. Please operate or charge the scale in an open area. Do not squeeze the power cord to avoid wire on fire. 5. Any suggestion for product is welcomed Preparing to Use the Scale 1. Locate the scale on a firm level surface free from vibrations for accurate weight readings. 2. Adjust the four levelling feet (if fitted) to set the scale pan level. 3. Avoid operating the scale in direct sunlight or drafts of any kind. 4. If possible avoid connecting the scale to ac power outlet sockets which are adjacent to other appliances to minimise the possibility of interference affecting the performance of the scale. 5. Remove any weight that might be on the weigh pan before the scale is switched on and avoid leaving weight on the pan for long periods of time 6. All goods weighed should be placed in the centre of the weigh pan for accurate weighing. The overall dimensions of the goods being weighed should not exceed the dimension of the weigh pan. 7. Once the scale has been powered on, it will go through an LCD display test and it is ready for use when the display shows zero. 8. The scale requires 15~20 minutes warm up before operation to ensure best accuracy 9. Please note when the symbol keeps flashing on the screen, the batteries need to be recharged. 10. Introduction of Storage Battery Thank you for purchasing EXCELL Weighing Indicator, to help use the product properly, operate smoothly, and extend its life cycle, please read this manual carefully.

No burning Caution Corrosion Due to the storage battery adopt the advanced free-maintaining technique, customers need not to replenish electrolyte. The scale should be recharged every 3 months to prevent failure of the internal rechargeable battery. 1. The battery should be charged for 8~10 hours. 2. The temperature of battery should below 45℃. Maintaining 1. Please do not discharge with over-current when using the battery. Please charge the battery after discharging current. 2. Please take down the battery when the scale is not used for a long time or break the connection of cathode. 3. Do not short the battery terminals to check whether there is current. Please check whether the connection point is firm to guarantee good connection. 4. The battery should be replaced by specialized person. No reverse-battery or the product will be damaged. a) Anode of battery should be connected with Anode of product battery（usually red cable） b) Cathode of battery should be connected with Cathode of product battery (usually brown cable or black cable) c) See the picture following Safety warnings 1. The electrolyte of battery is caustic which causes metal, cotton, etc to corrode. 2. The hydrogen will be resolved when using or charging the battery and it will cause explosion when approaches fire. Brown cable(or black cable) connected with Cathode of battery Red cable connected with Anode of battery Warning explosion Children faraway
