Getting Started
To begin:
1. Turn the power switch on the back of the chair to Off, wait
approximately five seconds, then turn it back On.
2. Wait 30 seconds while a system check is performed, then verify
that the problem still exists.
3. If the problem still exists, choose from the following issues:

Power
Step 1: Check the power LED.
Check the status of the power panel LED, located on the back of the
left-hand armrest above the power switch. If the power LED lights, go to
“Step 4: Replace the AC outlet fuse.”
Step 2: Check the power cord.
1. Verify that the power cord is plugged securely into the chair’s power
panel and is not damaged.
2. If the power cord is damaged, replace the power cord.
3. If the power cord connection is not secure, secure it, then recheck
the power LED status.
4. If the power LED lights, but there is still no massage mechanism
movement, see "Step 4: Replace the AC outlet fuse" on page 3.
Step 3: 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.
My arm vibration
started automatically
and cannot be turned
off by pressing the
Arms button on the
remote control.
If this occurs, there is a problem with the circuit
board. Replace the backrest:
DEALER NOTE: You may wish to replace the
daughter board instead of the complete backrest
assembly.

massaging properly See "Massage Functions" on page 5.
My backrest won’t
recline/incline See "Recline/Incline" on page 9.
My convenience outlet

Step 4: Replace the AC outlet fuse
Even though the power panel LED (located on the back of the left-hand
armrest) is lit, the AC outlet fuse may still be blown or broken, which
interferes with the remote control function. Replace the fuse.
The AC outlet fuse is the left of the two fuses, located on the power
panel.
To replace the fuse:
1. Turn the power switch to OFF and unplug the chair from the wall
outlet.
2. Using your fingers, turn the fuse holder knob (located on the power
panel) approximately 1/8 turn counter-clockwise.
The fuse holder pops out.
3. Replace it with a new fuse of the same rating.
4. Reinsert the fuse holder into the power panel, then turn it 1/8 turn
clockwise to secure it.
5. Plug the chair back into the wall outlet and turn it on.
6. Verify that the remote control LEDs now light.
Step 5: If the chair is still not receiving power, replace the
backrest.
Remote
If one or more remote control LEDs do not light when you
push the corresponding button, but the function the button
controls works properly:
The remote control is not working properly. Verify that the remote control
cable connection to the backrest cover is secure. If that does not solve
the problem, replace the remote.
If the remote control LED lights but the function it controls
is not working properly:
The problem is most likely in the function controlled by the remote, not
in the remote itself. See "Massage Functions" on page 5 for further
diagnosis.

Foot and Calf Massager
The foot and calf massager hesitates when changing
directions:
This is due to the gears shifting, and is perfectly normal.
The foot and calf massager circulate function will not shut
off:
If this occurs, there is a problem with the circuit board. Replace the backrest:
The foot and calf massager is not massaging, vibrating,
retracting or deploying:
IMPORTANT
The foot and calf massager must be fully deployed and locked
into position with the massage wells facing up for the foot and
calf massage and circulation functions to work.
1. Using the remote control (Legs Down button), attempt to fully retract
the foot and calf massager until it beeps twice, and then fully deploy
it until it beeps twice.
2. If the foot and calf massager will not retract/deploy, do the following:
a) Pull up on the foot and calf massager rotation release handle,
then rotate the foot and calf massager away from the chair
until you hear and feel it lock into place. The smooth side of

HT-1650 Troubleshooting Guide 5
the foot and calf massager is now facing up.
b) Pull up on the foot and calf massager rotation release handle,
then rotate the foot and calf massager back toward the chair
until you hear and feel it lock into place.
c) Without pulling the rotation release handle, gently try to rotate
the foot and calf massager away from the chair again. It
should be locked in place, unable to rotate.
d) Reattempt to retract/deploy the foot and calf massager. If the
foot and calf will still not retract/deploy, a sensor in the chair
base is not working properly. Replace the chair base.
3. If the foot and calf massager circulation function is not working,
replace the foot and calf massager.

minutes.
3. Check the left and right sides of the backrest to determine if either
side feels warm.
4. If either side does not feel warm, replace the backrest.
Arm vibration
Determine whether the vibration is not working in just one arm or both
arms, then do one of the following:
• If the vibration is not working in one arm only, replace the
vibration unit in that armrest.
• If the vibration is not working in both arms, replace the backrest.
DEALER NOTE: You may wish to replace the daughter board
instead of the complete backrest assembly.

the air bags stay inflated—Replace the backrest.
DEALER NOTE: You may wish to replace the daughter board

wire that is not connected properly. Do the following:
1. Power off the chair.
2. Facing the back of the chair, locate the side panel on the lower
right-hand side.
3. Using a Phillips-head screwdriver, remove the two screws that
secure the side panel, then remove the side panel by pulling gently
on the cables to release it from the chair frame. (The side panel
remains attached to the air hose).
4. Locate the large connector behind the side panel, then disconnect
it.

5. Gently pull on the wires that lead to the large connector. If any of the
wires comes out of the connector, this confirms that this wire
connection is the problem.
6. Push the wire into the connector until it clicks, then pull gently on
the wire to confirm that it cannot come out of the connector.
7. Reconnect the two connectors you disconnected in step 4.
8. Push the cables and connectors back into the lower right-hand side
of the chair. The large set of cables fits into the slot on the end of the
side panel.

Recline/Incline
Remote beeps once when Recline/Incline buttons are
pushed:
If you hear a single beep when you push the Recline and Incline
buttons, the backrest actuator is not working properly. Replace the
backrest actuator.
Remote beeps twice when Recline/Incline buttons pushed:
If the backrest is in a fully inclined position and you hear two beeps
when you push the Recline and Incline buttons, it means the safety
sensor has likely failed.
1. Make sure that nothing is pressing on the safety sensor.
2. Tap the safety sensor with your foot to ensure that it didn’t get stuck
during shipping.
3. If the problem still exists, replace the safety sensor.

works when plugged into a wall outlet.
3. Turn the power switch to OFF and unplug the chair from the wall
outlet.
