PCX-720 Troubleshooting Guide 

1

This Troubleshooting Guide walks you step-by-step through the 
diagnosis of PCX-720 customer problems. It is important to follow 
these steps carefully, to ensure that the problem is diagnosed 
correctly, and therefore the appropriate repair action is taken.

1. Reset the chair by unplugging it, then plugging it back in.

2. Push the PRO button and observe whether the blue LED lights. If 

it does not, the chair is not receiving power. See 

.

3. Choose from the following:

Replace the backrest actuator. 

If that does not solve the problem, do one of 
the following:

• For serial numbers CWC24130001 - 

CWC24130078, replace both the control 
panel and the main control module w/power 
cord.

• For all other serial numbers, replace the 

control panel.

When in ZeroG mode, you cannot raise the 
footrest, as ZeroG is a specific, neutral-posture 
position. This is normal. 

If you incline the chair slightly out of ZeroG 
mode, you can then further raise the footrest.
