SERVICE PROCEDURES
HT-R320
1. Replacing the fuses
2. Safety-check out
(Only U.S.A. model)
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
This symbol located near the fuse indicates that the
fuse used is show operating type, For continued protection against
fire hazard, replace with same type fuse, For fuse rating, refer to
the marking adjacent to the symbol.
Ce symbole indique que le fusible utilise est e lent.
Pour une protection permanente, n'utiliser que des fusibles de meme
type. Ce demier est indique la qu le present symbol est apposre.
3. To initialize the unit
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.
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 " Clear " is displayed, the preset memory and each mode
stored in the memory, are initialized and will return to the
factory settings.
5. Memory Preservation
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.
2. Press the STANDBY/ON button to Power Off.

1-2. Press the VIDEO 3 button, while the" Test - _ " is shown.
Unit will be in the state of " Test-4-00 ".
1-3. Repeat and press SPEAKERS B button to the " Test-4-29 " is shown.
2. Connect the lord resister (3 ohms) to the speaker terminals.
3. Check that the" Protect " is not shown, and speaker relays not turn OFF.
4. Check the each speaker terminals.
5. Connect the lord resister (1.5 ohms) to the speaker terminals.
6. Check that the " Protect " is shown, and speaker relays turn OFF immediately.
7. Check the each speaker terminals.
8. Press the STANDBY/ON button.

Regarding the power supply system of this unit.
<Function>
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.
<Purpose>
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.
<Necessity for a check of operation>
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.
<Procedure>
[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%.
(6) Check that the RL6901 and RL6902 are turned Off after about 5 seconds progress.
And the power supply changes to low-voltage mode.
(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.

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
