HT-Navitas Troubleshooting Guide 1
HT-Navitas Ascent Series Troubleshooting
This Troubleshooting Guide walks you step-by-step through the
diagnosis of HT-Navitas Ascent Series 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. Verify that the chair has not been used for more than three
consecutive cycles. If it has, power off the chair and allow 30
minutes for the chair to cool down.
NOTE
If you run the chair continuously for more than three
massage cycles, it may shut down to protect the chair from
overheating. This thermal protection is a safety feature.
2. Turn the power switch on the back of the chair base to Off, wait
approximately five seconds, then turn it back On.
3. Verify that the power switch LED lights to indicate that the chair is
receiving power. If it does not, see "Power" on page 3.
4. Verify that the problem still exists.

To Troubleshoot This
Issue: Do the following:
My remote control is
not working properly
(error code 90).
If the remote screen does not display any
text, or displays the text abnormally,
replace the remote. IMPORTANT: this
requires a software update; you must send
the appropriate software update kit with the
remote.
If replacing the remote does not solve the
problem, replace the main PCB.
IMPORTANT: this requires a software
update; you must send the appropriate
software update kit with the PCB.
My backrest is not
massaging properly
(error codes E0,E4,
and E5)
Replace the massage mechanism, power
cable, and data cable.
If replacing the massage mechanism does
not solve the problem, replace the main
PCB. IMPORTANT: this requires a software
update; you must send the appropriate
software update kit with the PCB.
My backrest won’t
recline/incline (error
code E1)
Replace the backrest actuator.
If replacing the backrest actuator does not
solve the problem, replace the main PCB.
IMPORTANT: this requires a software
update; you must send the appropriate

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 cord.
Step 2: Check the wall outlet.
1. Plug a known working device, such as a 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: Replace the Main PCB.
Step 4: Replace the chair.
My calf massager
won’t massage (error
codes E6, E7, E8).

update; you must send the appropriate
software update kit with the PCB.
