Stainless steel pan 4. Product manual Keep the packaging material for your future use. 4.2 Level Adjusting Place the scale on a table. Check the water mark. If, bubble is not centre adjust the leveling feet until reach centre. Check the level when you change the location.

- 10 - 4.3 Connect Adaptor  To charge the battery insert the adaptor pin to jack. Adaptor simply plug into the mains power. The scale no needs to be turned on.  The battery should be charged for 12 hours for full capacity.  Left side of the display there is an LED to indicate the status of battery charging. When the scale is plugged into the mains power the internal battery will be recharged. If the LED is green, the battery has a full charge. If it is red, the battery is nearly discharged and if yellow, the battery is being charged.  Do not use any other type of power adaptor than the one supplied with the scale.  Verify that the AC power socket outlet is properly protected. Note: Please charge the battery before using the scale for the first time. Adaptor Jack Power Key

- 14 - 6. OPERATION Initial Start-Up Warm-up time of 15 minutes stabilizes the measured values after switching on. 1. Power ON/OFF Power switch is located below the right side of the scale. Switch on the scale by pressing on/off. The display is switched on and the self test is started. If you want to switch off press again the key. 2. Zero Environmental conditions can lead to the balance exactly zero in spite of the pan not taking any strain. However, you can set the display of your balance to zero any time by pressing key and therefore ensure that the weighing starts at zero. 3. Tare The weight of any container can be tared by pressing key, so that with subsequent weighing the net weight of the object being weighed is always displayed.  Load weight on the pan.  Press key. Zero is displayed, and tare is subtracted.  Remove weight from the platform. Tared weight is displayed. It can set only one tare value. It can display with a minus value.  Press key. Zero is displayed, tare weight is cleared.
