7Cautions for installing the scaleConsider the following conditions to get the most out of your scale.? Install the scale where the temperature and relative humidity is stable. There is nodraft and a stable power source is available.? Install the scale on a solid and level surface.? Do not install the scale in direct sunlight.? Do not install the scale near heaters or air conditioners.? Do not install the scale where there is flammable or corrosive gas present.? Do not install the scale near equipment which produces magnetic fields.? Do not install the scale where there is apt to be static electricity, in a place wherethe relative humidity is lower than 45% RH. Plastic and isolators are apt to becharged with static electricity.? Do not use an unstable power source.? When the scale is installed for the first time, or the scale has been moved, carry outcalibration as described in “8. CALIBRATION”.4-3. Power sourceFor the power source, the AC adapter or C size dry cells can be used.When using the AC adapterUse a stable power source. To use the AC adapter, insert the AC adapter plug into theAC adapter jack on the rear side of display pod.? Confirm the AC adapter type is correct for your local voltage.When using the batteriesPrepare 4 x C size (R14P/LR14) dry batteries. The batteries are not included in theproduct. The scale can be used continuously for about 150 hours using the alkalinebatteries.1. Turn of the scale and disconnect the AC adapter if used.2. Slide the battery cover off3. Push the battery case inside the display pod and take it out.4. Insert four new dry cells into the battery case.5. Push the battery case into the display pod as before.6. Attach the battery cover.? Take great care of the polarity of batteries. The polarity marks areshown in the battery case.? Replace used batteries with four new ones when “lb0” is displayed.? Do not mix used and new batteries. It may cause damage to thebattery or product, if used.? Do not mix the battery type. It may cause damage to the battery orproduct.? The battery life depends on the ambient temperature.? Remove batteries from display pod when the scale is not to be usedfor a long time. They may leak and cause damage.? Damage due to battery leakage is not covered by the warranty.
