2. Important Notes for Users

Handling Tips

This scale is a precision instrument utilizing state-of-the art technology. To keep the unit in the best
condition, follow these instructions carefully.

• Do not attempt to disassemble the measuring platform and display.

• Avoid excessive impact or vibration to the unit.

• Place the unit in an area free from direct sunlight, heating equipment, high humidity, or extreme

temperature change.

• Never submerge in water or spill chemical liquids. To clean, use a dampened cloth and mild detergent.

• If the product will not be used for a long period, remove the batteries before storage.

Moving the Scale

The scale has two rear wheels on the back of the platform. To avoid damage, use the wheels when moving
the scale. Hold the display head securely and tilt the scale back about 30-45 degrees. Wheels will allow
easy movement. IMPORTANT: Any time the scale is moved or re-located, be sure to press the ‘Zero’ key
before use.

Disabling Key Sounds

To confirm a key operation has been selected, a “beep” will sound when any key is pressed. To disable
this sound, press the up arrow and down arrow keys simultaneously for three seconds. To re-activate the
key sound, press the up arrow and down arrow keys simultaneously again for three seconds. The volume
of this beep sound is not adjustable.

Changing Measurement Units

This function can be used to change the measurement units on the Weight display: lb, kg, and fractional
lb. The measurement unit keys are located on the left display panel. You may press this key before or
while the user is on the platform.

Press ‘LB’ to set to pound mode. Decimal weight value in pound mode (0.1 lb increments)
Press ‘KG’ to set to kilogram mode. Decimal weight value in kilogram mode (0.05 kg increments)
Press ‘LB (F)’ to set to fractional pound mode. Fractional weight value in pound mode (1/4 lb increments)

If the scale is to be disassembled,
please use this plastic tool to
separate the two pillars.

1. Carefully remove all components from the box.

2. Place all items on the floor side by side. Make sure not to excessively pull the wire harness that

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.
