PCX-720 Troubleshooting Guide
Step 1: Check the power cord.
1. Check the entire length of the power cord for damage; if the power
cord is damaged, replace the control module.
Step 2: Check the wall outlet.
1. Plug a different device, such as a known working lamp, into the AC
outlet into which the chair is plugged.
2. If the device does not work (is not receiving power), the AC outlet is
most likely not working. Plug the chair into a different AC outlet to
verify that it receives power.
Step 3: If the chair is still not receiving power, do one of
the following:
1. For serial numbers CWC24130001 - CWC24130078, replace both
the control panel and the main control module w/power cord.
2. For all other serial numbers, replace the main control module
w/power cord.
