“HC” is displayed on control box
Possible Causes:
Person or object is obstructing the motion of the X-arm™.
One of the large drive screws has dirt or something on it.
The linkages are rubbing against something.
A motor cable has a short.
How to Correct:
1. Unplug X-arm™ from power for at least 10 seconds..
2. Check that the TV and X-arm™ are not trapped against the wall or any other
object.
3. Plug in X-arm™, turn on the power and try to move the X-arm™ using the
remote control. If it works properly, do not continue to the next step.
4. With the X-arm™ powered on, insert the provided plastic pointer in the
Selector hole on the side of the X-arm™ and press it until “t” shows on the LED
display.
5. Using the remote control, straighten X-arm™ so that it is parallel with the
wall, and then press the “Set” button on the control box for three seconds. The
X-arm™ should return to the home position against the wall.
6. Turn the power switch on the control box to “0” (OFF).
7. Hold down the Set button on the control box while switching the power
switch to “1” (ON). Continue holding down the Set button for 5 seconds until
the display reads CT.
8. Stand back while X-arm™ moves through the calibration sequence, moving in
and out, left and right and up and down.
9. X-arm™ is done calibrating when it goes back to the home position against
the wall.
10. Turn on the X-arm™ and test to see if it is operating normally. If it is not,
remove the TV from X-arm™ and continue.
11. Check that there are no foreign objects in the switches and motors in the
areas shown in the picture.
12. Check to see that the wire connections are securely connected and clean
any substances that are found around the large drive screws.
13. Check the motors for faults in the areas shown in the picture.
14. Plug in X-arm™. Turn on the power, and try to move X-arm™ using the
remote control.
