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).
