e. If air is not coming out of the air pump, remove connectors CN3 and
CN30 from the main PCB, switch the cables, then plug them back into the
opposite connector.
i. If the problem remains, request a footrest air pump.
ii. If there is now air flowing, request a main PCB.
iii. Switch the connectors back to their original location.
B. If the air bags all inflated during Tech Screen 2 Test 09, request a main PCB.
If the foot/calf massager will not inflate or deflate in ONE AREA only:
A. If the air bags inflated during Tech Screen 2 Test 09, request a main PCB.
B. There is likely a kink in a hose inside the foot/calf massager or a defect in the air
distribution valve inside the foot/calf massager. Request a foot/calf massager.
If the foot/calf massager air will not deflate AT ALL:
A. Power off the chair, wait for 30 seconds, and observe whether the air bags deflate.
B. If the air bags deflate, request a main PCB.
C. If the air bags do not deflate, request a foot/calf massager.
If you hear a noise other than a soft humming while testing the air system:
If the above test produces any noise other than a soft humming, remove the rear plastic shroud
and plastic PCB cover and ensure that the footrest (left-hand) air pump is tightly secured to the
base. If it is, request a footrest air pump.
If the foot/calf massager air bags are suspected of leaking:
A. Request a foot/calf massager.
Step 10: Test the underfoot rollers and foot sensors.
A. Place your feet into the foot/calf massage wells, with your heels pressed against the
bottom of the massage wells (there are sensors in both the heels and the toes).
B. From the remote main menu, select AUTO, then select any auto program.
C. Confirm whether shortly after the massage begins, the foot/calf massager extends/
retracts to measure your leg length.
D. If the foot portion of the foot/calf massager does not extend/retract, or
hesitates/freezes intermittently, request a foot/calf massager and main PCB.
E. Confirm that the rollers on the underside of your feet are moving.
F. If the underfoot rollers are not moving:
1. Lift the foot/calf massager and disconnect the connector.
2. Inspect the connection for damage.
a. If there is damage on the harness side, request a foot/calf massager.
b. If there is damage on the bulkhead side, request a bulkhead harness.
