connects the base (1) to the top assembly (6).
3. Carefully pull wire harness on topside of lower pillar (2) as pillar is inserted into the base (1). This will
minimize the length of straight wire and ease assembly.
4. Once the lower pillar (2) is placed firmly in the base (1), tighten the knob (3) to the threaded stud located
underneath the base.
5. Snap the top assembly (6) into the lower pillar assembly (2). Make sure to push in the excess length of
coiled wire harness (8) into the open ends of the two pillars as you bring them together. Be careful not
to pinch the coiled wire harness (8) between the two pillars.
6. Assemble the height rod arm (7) to upper height rod (5) from the bottom of upper height rod.
7. Assemble the top height rod assembly (5) to the lower height rod (4). Slide the assembled height rod
into the height rod opening on the pillar assembly. Push all the way down.
Note: For scales without height rod skip steps 6 & 7.

8. General Troubleshooting
Weight Capacity: ‘E’
If the weight is less than 10 lbs, the Weight LCD will display the weight, however, the reading
will not lock in. Auto-on function will not work if the weight is less than 30 lbs.
If the weight exceeds the scale’s maximum weighing capacity, the display panel will register ‘E’
and the scale will shut off in 2 seconds.
Weight LCD
Low Battery Warning: ‘LOWBATT’ / ‘LoAA,’ ‘nobAt,’ ‘Ad Er,’ ‘Lo L’
The scale is operated by three replaceable AA alkaline batteries. If the AA batteries are low, ‘LOWBATT’
icon will flash on the Weight LCD, and ‘LoAA’ will flash on the Clock LCD alternating with clock for two
seconds. Please replace with three new AA alkaline batteries immediately. Please refer to Inserting
Batteries for instructions. If you see ‘Ad Er’ or ‘nobAt’ on the weight LCD, make sure the batteries are
properly installed and have contact with the battery chamber.
The clock on this scale is operated by one replaceable 3-volt CR123 Lithium battery. If the lithium
battery is low, ‘LOWBATT’ icon will flash on the Weight LCD, and ‘Lo L’ will be displayed on the Clock
LCD alternating with clock for 2 seconds. This will continue until the lithium battery runs out, showing the
Clock LCD panel blank. Please replace with one new lithium battery immediately. Please refer to Inserting
