The M-550 runs on four ‘AA’ alkaline batteries.

When

for the scale to be used and the batteries should be replaced.

The four ‘AA’ size alkaline batteries are contained in a compartment inside the scale.

Access is via a removable cover on the underside of the scale, as shown below:

TARE

1. The ZERO/TARE key can be used to remove any unwanted weight from the scale’s

from the reading, to leave only the person’s weight showing. To do this, place the

shoes on the scale and press the ZERO/TARE key once.

The weight of the shoes will then be zeroed off.

3. Press the HOLD/BMI button to decrease the height and ZERO/TARE to increase

the height.

4. When the correct height is showing on the display, press the ON/OFF button.

5. BMI will automatically be calculated and the display will show weight and BMI in

rotation.

6. Press ON/OFF to disable the BMI function.

Setting the Bluetooth Function

instructions should be followed when you are connecting to a system or device configured
