ZeroG 4.0 Troubleshooting
This Troubleshooting Guide walks you step-by-step through the
diagnosis of ZeroG 4.0 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. Turn the power switch on the back of the chair base to Off, wait
approximately five seconds, then turn it back On.
2. Verify that the backrest massage mechanism and the foot and calf
massager paddles move when you power on the chair. If they do
not, see "Power" on page 2.
3. Wait 30 seconds while a system check is performed, then verify
that the problem still exists.
4. If the problem still exists, choose from the following issues:,
To Troubleshoot This
Issue: Do the following:
My remote control is
not working properly
Replace the remote.
My backrest is not
massaging properly
Replace the massage mechanism.
My backrest won’t
recline/incline
Make sure you are pressing and holding the up
or down arrow for at least five seconds; it can
take several seconds to activate. If this does not
resolve the issue, replace the backrest actuator.
If that does not solve the problem, replace the
chair.
My foot and calf
massager is not
massaging properly
Make sure the foot and calf massager is locked
into place. If the problem remains, replace the
foot-and-calf massager.

Power
Step 1: Check the power cord
1. Verify that the power cord connection to the chair’s power panel is
secure and that the cord is not damaged.
2. If the power cord is damaged, replace the power panel.
Step 2: Check the wall outlet
1. Plug a different device 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, replace the
main PCB
If this still does not solve the problem, replace the chair.
My foot and calf
massager won’t
raise/lower
Make sure the foot and calf massager is locked
into place. If the problem remains, replace the
footrest actuator.
My seat massage is not
working
Replace the chair.
There are greasy spots
on the upholstery.
Lightly dampen a cloth with Pledge or other
similar furniture cleaner and wipe the area to
remove the spot.
