Remove the scale from its shipping container and inspect it for shipping damage. Should evidence of damage be found, the carrier should be contacted at once. Retain the shipping container for future storage or shipment of the scale. 2. Install the batteries. Refer to BATTERY REPLACEMENT section. If batteries are not to be used, plug the optional AC power adapter into the power jack on the back of the scale. 3. Place the scale on a stable, vibration-free location away from direct sunlight and any rapidly moving air source. If the AC power adapter is being used, make certain the cord is stored out of the way of normal traffic. 4. Plug the optional AC power adapter (if used) into a 115 VAC 50/60 HZ grounded wall outlet. 5. The scale is now ready for use. BATTERY REPLACEMENT This instrument is designed for operation from either four (4) AA Alkaline batteries or an optional AC power adapter. A low battery signal is provided in the weight display to indicate when the batteries should be replaced. Remember to use only size AA Alkaline batteries in the instrument. 1. Turn the scale bottom side up and remove the single screw from the battery compartment cover. Remove the cover from the base by lifting up and pulling outward as shown. 2. Remove the old batteries and replace with fresh ones. Make certain the + and - ends of the batteries match the positions shown on the scale circuit boards as shown. Replace the battery compartment cover and retaining screw. Battery Compartment Cover Battery Compartment Cover Pull cover out and up OPERATION 1. Press the ON-TARE key to turn on the scale. 2.
