LED Flashing
LED flashing specification at the time of the error
Display method
Make the OPC LED flash using the [MENU] key on the remote control since the display for service persons is identified by the number of flashings (once to 5 times). Even if the [MENU] key is pressed again, it does not return to the display for customers (only the power LED flashes).
After recovering from an error, if the same error cannot be generated again, refer to MONITOR ERR CAUSE on the adjustment process screen. shing method
Synchronize the phases of the power LED and OPC LED.
If the LEDs have different number of flashings, adjust the flashing cycle to that where the LED flashes more times
Cleaning the LCD
Ensure you unplug the power cord before cleaning the LCD. The cabinet as well as the operation panel is made of plastic. Avoid using benzene or thinner, as these can damage the finish on the cabinet.
Do not use volatile agents such as insecticides on the LCD. Do not attach rubber or plastic items on the LCD for long periods of time.
The effects of some of the agents in the plastic may cause damage to the quality or finish of the LCD.
Wipe off dirt gently with a soft flannel cloth.
When the dirt is hard to remove, soak a cloth in a neutral detergent diluted with water, wring the cloth well and then wipe the LCD.
Strong cleaning detergents may discolour, warp or damage the coating on the LCD.
Ensure you test on a small, inconspicuous area on the LCD before using.
Cleaning the exhaust and intake vents
Use a vacuum cleaner to clean dust from the exhaust vent and the intake vent.
