The following guide will help you to solve 
common problems:

1. Unplug the adapter 

from the outlet, then
unscrew it from the 
electronic control 
box and set the 
adapter aside.

2. Slide the adjustable 

rail to its widest setting.

3. Loosen the locking screw 

and slide it off the black tabs.

4. Slowly lift the scale by the handle.

Avoid letting the rails bang together.

5. Wrap an elastic cord (64010) around each end of 

the rails and hook the cord ends together.

6. Unscrew the scale cable from the control box and

firmly place the control panel box on the velcro tape 
of the center column. Wrap the cable around the 
center column above the control panel box and secure.

7. The scale is now ready for transportation or storage.

8. Remember to keep the adapter with the scale.

9. For additional convenience and protection of your

portable wheelchair scale, a scale storage bag is
available from your Tanita representative.
