7.1.9 SERVICE TEST MODE
1. How to enter the test mode
• Turn the power on while short-circuiting with short circuit point SERVICE (pin 43) and VE +5 on the PC Board.
• To release the test mode, pull out the AC power cord or turn the power off.
2. Start operation
• Initial function is a DVD / CD and cannot enter the DEMO mode.
3. Function and operation in the service test mode
Difference with the normal mode
• Even if there is not an AC pulse, operation is possible. Operation can only in the DVD tuner section if it supplies necessary DC power
supply even if there is not the amplifier section.
• Release the forced power off function by the protection function. It is easy to perform the diagnosis of the malfunction point.
• Other functions and operations are the same as the normal mode.
4. Version indication of the microcomputer
• When pressing the STOP key for about 8 seconds, version indication of the microcomputer and number of times of operation of the door
(count ups by close completion) and total time of the power supply on are indicated.
Indicated condition is the function except a tuner mode in the power on state. (Memory is cleared in the tuner mode.)
• So that number of times of operation of a door and total time time of the power supply on are backing it up, it is effective so long as
backup power supply does not break down.
Do not clear it by the memory clear and the line test mode.
