PCX-720 Troubleshooting Guide 1

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.

Getting Started

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. Choose from the following:

To Troubleshoot This

Issue Do the following:

My chair will not

recline/incline.

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.

My footrest will not

raise when I’m in

ZeroG mode.

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.

My footrest will not

raise/lower.

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. Replace the footrest scissor assembly.

My memory buttons

don’t work.

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.

When I press the PRO

Mode button nothing

happens (other than

the blue LED lights).

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.

My headrest falls off

when I recline all the

way into Pro Mode.

Your chair 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.

My chair wobbles

slightly/sits uneven.

Carefully check underneath to determine if one

of the four plastic feet is broken/missing. If so,

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.

To Troubleshoot This

Issue Do the following:

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.
