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.

5. If the problem still exists, choose from the following issues:,

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.

lower back, hip, seat

or foot air massage is

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).

Replace the calf massager.

If replacing the calf massager does not

solve the problem, replace the main PCB.

update; you must send the appropriate

software update kit with the PCB.

My foot-and-calf

massager won’t

deploy/retract (error

code E2).
