Troubleshooting Guide

What might seem to be a malfunction in your unit may just be the result of slight misoperation or miswiring. Before calling service, first check the following table for possible problems.

?The power does not turn ON.

✔The fuse has blown.

☞After checking for short circuits in the wires, replace the fuse with one with the same rating.

✔The motor is not attached to the bracket securely.

☞Attach the motor to the bracket until it clicks.

?Nothing happens when the buttons are pressed.

✔The computer chip in the unit is not functioning normally.

☞Press the reset button on the unit (page 3).

?The screen is dark.

✔The unit is in a location where temperature is low.

☞If the temperature of the monitor unit drops, the screen may appear darker when power is first turned on due to the characteristics of a liquid crystal panel. Wait a while after turning power on for the temperature to rise. Normal brightness will return.

✔The "BRT", "BLK", "CONT", and other screen control levels are too low.

☞Adjust the "BRT", "BLK", "CONT", and other screen controls to obtain appropriate illumination, or restore them to factory-set levels with reference to <Initializing the User Settings> (page 10).
