TARE 
 

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

shoes on the scale and press the ZERO/TARE key once. 
The weight of the shoes will then be zeroed off. 

2.  Weigh the individual as normal. 
3.  Remove the shoes and press ZERO/TARE again to cancel the Tare value and 

return the scale to zero.

1.  After the patient stands on the scale, press and hold the HOLD/BMI key for three 

seconds. The scale will enter BMI mode. 

2.  The display will show the last inputted height. 
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.

instructions should be followed when you are connecting to a system or device configured 
to work with Marsden Bluetooth scales.

and hold ZERO/TARE for three seconds. The display will show ‘SETUP’.

until the display shows ‘BLUET’. 

3.  Press ZERO/TARE to enter Bluetooth setting mode.
