HT-7450 Troubleshooting Guide 3
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: Replace the AC outlet 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, open the fuse compartment on the power panel,
then turn the left-hand fuse holder knob (located on the power
panel) counter-clockwise to remove it.
3. Replace the fuse with a new fuse of the same rating.
4. Reinsert the fuse holder into the power panel, then turn it clockwise
to secure it.
5. Close the fuse compartment lid.
6. Plug the chair back into the wall outlet and turn it on.
7. Verify that the chair is now receiving power.
Step 4: If the chair is still not receiving power, replace the
chair base
If this does not solve the problem, replace the backrest.
