3.5 Checking the mains voltage The following Safety recommendations must be observed when connecting the weighing machine to the mains: The weighing machine may only be operated with the power adapter supplied. Check before connecting the power adapter to the mains supply, that the operating voltage stated on the power adapter agrees with the local mains voltage. If the operating voltage is not the same as the mains voltage, the power adapter must, on no account, be connected to the mains supply.
4.1.1 Selecting the auto backlight mode Press the UNIT key, the display will show L_ON, L_OFF, or L_Au. Press the ZERO key to select. L_ON means the auto backlight function is active. L_OFF means the auto backlight function is inactive, and L_Au means the auto backlight function is on Auto. 4.1.2 Selecting the auto shut off mode Press the UNIT key again, the display will show A_ON or A_OFF.

NOTE: X is the calibration weight which can be set according to your requirements. The weight needed when re-calibrating your Tree scale needs to be at least half (1/2) of the capacity of the scale with two thirds (2/3) being ideal as this will give you the most accurate reading. (Ex: For a 10,000g scale you would need at least 5,000g) Press the Zero key to confirm the calibration weight. The display will show CAL and then the AD value. Once the stable indicator “(.)” is displayed, press the UNIT key.
housing with a soft brush or a soft, lint-free cloth, moistened with a mild soap solution. The platter can be cleaned under running water. Ensure that both parts are completely dry before they are re-installed on the scale.
