PCX-720 Troubleshooting
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 "Power" on page
3.
3. Choose from the following:
To Troubleshoot This
Issue
My chair will not
recline/incline.
My footrest will not
raise when I’m in
ZeroG mode.
Do 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.

To Troubleshoot This
Issue
My footrest will not
raise/lower.
Do the following:
If the footrest will not raise/lower at all, replace
the footrest 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.
My footrest is
physically bent/broken.
My memory buttons
don’t work.
When I press the PRO
Mode button nothing
happens (other than
the blue LED lights).
My headrest falls off
when I recline all the
way into Pro Mode.
Replace the footrest scissor assembly.
Verify that you are using the memory buttons
as described in the Use & Care manual.
f 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.
Pressing the PRO button enables you to recline
the chair beyond the ZeroG position. However,
the chair does not automatically recline.
Use the control panel recline and incline
buttons to recline to the desired position.
Yo ur ch air came with two headrest screws and
an Allen wrench, contained in a plastic bag
along with your Use & Care manual and other
documentation.
Follow the assembly instructions in the Use &
Care manual to properly install the headrest,
using the two screws to secure it.
Carefully check underneath to determine if one
of the four plastic feet is broken/missing. If so,
My chair wobbles
slightly/sits uneven.
replace the plastic foot (spare part contains a
set of four).
If your chair is on an uneven floor, you can
adjust the plastic feet to compensate.

Power
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.
