5. Memory Preservation
This unit does not require memory preservation batteries. A built-in memory power backup system preserves the contents of memory during power failures and even when the power cord is unplugged. The power cord must be plugged in order to charge the backup system. The memory preservation period after the unit has been turned off varies depending on climate and placement of the unit. On average, memory contents are protected over a period of a few weeks after the time the unit has been turned off. This period is shorter when the unit is exposed to a very humid climate.
2. Safety-check out
After correcting the original service problem perform the following safety check before releasing the set to the customer Connect the insulating-resistance tester between the plug of power supply cord and terminal GND on the back panel. Specifications: More than 10Mohm at 500V
3. To initialize the unit
This device employs a microprocessor to perform various functions and operations. If interference generated by an external power supply, radio wave, or other electrical sauce results in accident which causes the specified operations and functions to operate abnormally. To perform a result, please follow the procedure below. 1. Press and the hold down the VIDEO 1 button , then press the STANDBY/ON button when the unit is Power ON. 2. After " Clea r " is displayed, the preset memory and each mode stored in the memory, are initialized and will return to the factory settings.
4. How to check version of microprocessor?
Main microprocessor Q7008 1. Press and the hold down the DISPLAY button , then press the STANDBY/ON button when the unit is Power ON. Version is displayed on FL display only for 3 seconds. ex.

OUTPUT LEVEL & THERMAL DETECTION
Regarding the power supply system of this unit.
1. High-voltage mode Usually, the power supply supplies high voltage to the power amplifier circuit when the relay (RL6901) is turned On. 2. Low-voltage mode When as follows, a power supply changes to the state of supplying low voltage when the relay (RL6901) in turned Off. (1) Excessive output signal is continuously outputted from power amplifier. (2) Temperature of a heat sink over 80 degrees. 1. The loss which power amplifier generates is decreased. As a result, the miniaturization of a heat sink is realized. 2. Corresponds to a safety standard.

Q6303
May not notice the fuse (F6901, F6902) broken in the case of repair. Because the power supply is continuing supplying voltage from the High side of SEC1 at high-voltage mode. When a power supply circuit changes to low voltage mode, amplifier does not operate. Therefore, it is very important to check operation of this power supply system containing a fuse. [NOTE] Don't connect speakers or any load. Don't short speaker terminals. (1) Set the unit is Multi channel input state. (2) Set the master volume into the minimum. (3) Apply sine wave signal to MULTI CHANNEL INPUT (FL+FR+C+SL) terminals. (4) Connect an oscilloscope to speaker terminal of FL channel. (5) Adjust master volume so that a speaker output may become distortion about 5%.
High-voltage
(6) Check that the RL6901 and RL6902 are turned Off after about 5 seconds progress. And the power supply changes to low-voltage mode.
Low-voltage
(7) Adjust the master volume so that output voltage may become half.
(8) Check that the RL6901 and RL6902 are turned On after 2 to 3 minutes. And the power supply returns to high-voltage mode.

NOTE THE COMPONENTS IDENTIFIED BY MARK ! ARE CRITICAL FOR SAFETY REPLACE ONLY WITH PART NUMBER SPECIFIED. VOLTAGE (MEASURED WITH VOLTMETER) IS DC VOLTAGE.(NO INPUT SIGNAL). ALL PNP TRANSISTORS ARE EQUIVALENT TO 2SA1015-GR UNLESS OTHERWISE NOTED. ALL NPN TRANSISTORS ARE EQUIVALENT TO 2SC1815-GR UNLESS OTHERWISE NOTED. ALL DIODES ARE EQUIVALENT TO 1SS133 UNLESS OTHERWISE NOTED. ELECTROLYTIC CAPACITORS ( ) ARE IN uF/WV. ALL CAPACITORS ARE IN pF/50WV UNLESS OTHERWISE NOTED. EX) 030- 3pF 330- 33pF 331- 330pF 333- 0.033uF ALL RESISTORS ARE IN OHMS 1/4WATTS UNLESS OTHERWISE NOTED. THE THICK LINES ON PC BOARD ARE THE PRINTING SIDE OF THE PARTS. EX) PRINTING SIDE CIRCUIT IS SUBJECT TO CHANGE FOR IMPROVEMENT. NC=No mount of parts.

THE COMPONENTS IDENTIFIED BY MARK ! ARE CRITICAL FOR SAFETY REPLACE ONLY WITH PART NUMBER SPECIFIED. VOLTAGE (MEASURED WITH VOLTMETER) IS DC VOLTAGE.(NO INPUT SIGNAL). ALL PNP TRANSISTORS ARE EQUIVALENT TO 2SA1015-GR UNLESS OTHERWISE NOTED. ALL NPN TRANSISTORS ARE EQUIVALENT TO 2SC1815-GR UNLESS OTHERWISE NOTED. ALL DIODES ARE EQUIVALENT TO 1SS133 UNLESS OTHERWISE NOTED. ELECTROLYTIC CAPACITORS ( ) ARE IN uF/WV. ALL CAPACITORS ARE IN pF/50WV UNLESS OTHERWISE NOTED. EX) 030- 3pF 330- 33pF 331- 330pF 333- 0.033uF ALL RESISTORS ARE IN OHMS 1/4WATTS UNLESS OTHERWISE NOTED. THE THICK LINES ON PC BOARD ARE THE PRINTING SIDE OF THE PARTS.
