Operation to reset
The microcomputer may fall into malfunction (impos-
sibility to operate, erroneous display, etc.) when the
power cord is unplugged while power is ON or due to
an external factor. In this case, execute the following
procedure to reset the microcomputer and return it
to normal condition.
R-SG7
Pull the power plug from the receptacle, and then plug
it in again while keeping the “on/standby” key pressed.
÷Please note that resetting the microcomputer clears the
contents stored in it returns it to condition when it left the
factory.

2. INITIALIZING
2-1 The method of the initializing
The system is initialized when the power is turned on while
pressing the [ON/STANDBY] key.
(1) Contents of the operation
• All the functions are initialized.
3. BACK UP
This function holds the current state of the unit even if the
AC power of the receiver is turned OFF.
(1) Operation outline
The backup state set command(CE) of a microcomputer
is set low when the AC power is turned OFF. The micro-
computer detects the signal and enters the stop state.
The microcomputer is reset when the AC power is turned
ON. The data for backup state comfirmation is checked
by reset processing. The microcomputer is initialized
when the data was destroyed. If it is not destroyed, the
microcomputer is started in the backup state.
• The data for backup state comfirmation is written in a
RAM area.
• The microcomputer is set to the stop mode so as to save
the power consumption.
• A backup state set command signal is detected by a timer
interrupt of 1 msec.
• The backup guarantee period is set in a circuit.

CIRCUIT DESCRIPTION
5. TEST MODE
5-1 AMP test mode using main unit's keys
• Entering the AMP test mode
Turn on the power while pressing the[BAND] key.
• Canceling the AMP test mode
By turning off the power, the systen is initialized and the
test mode is canceled.
5-1-1 Contents of AMP test mode
(1) Automatic on/standby ON
• The POWER ON state is entered when the power is
turned on whille pressing the [BAND]key. All functions are
then initialized and activated in the all-lighting mode.
• Sub-clock oscillation diagnosis function
The oscillation diagnosis (existence of oscillation and
measurement of period) of a sub-clock is performed
before the test mode is entered. If the diagnosis result is
OK,the system enters the test mode. If the diagnosis
result is NG,the oscillation of the sub-clock is diagnosed
again. If the result is OK, the system enters the test
mode. If the diagnosis result is continuously NG five
times, the system stops with ERR1 and ERR2 displayed.
(2) All- lighting mode
• All the fluorescent display indicators and LED lamps light
when the power is turned on while pressing the [BAND]
key. After that, all- lighting mode is canceled when any
main unit's key is pressed. The normal display is obtained
when the selector is set to TUNER then appears.
(3) Others
• The AMP test mode is not terminated even if the selector
is set to positions other than TUNER.
• In the AMP tesst mode,the muting during mode selection
is not controlled. However, the operation during the
power-on sequence is the same as the normal operation.
• The SP protection operation is also the same as the nor-
mal operation.
• In the AMP test mode using main unit's keys,the keys
below provide a special operation according to the posi-
tion where the selector is set. The main unit key's except
described below and the rotary encoder provide the nor-
mal operation.
(4) When selector is set toTUNER
1Write data in the unused area of E2PROM, then read the
written data. If the read data is the same as the written
data, RAM OK is displayed in the fluorescent display indi-
cator. If the former is the different from the later, RAM NG
is displayed.
2Set the TUNER ATT to OFF and display the S level in
hexadecimal when the [ENTER] key is pressed . (ATT
OFF ✽✽is displayed in the fluorescent display indicator.)
3Set the TUNER ATT to ON and the display S level in
hexadecimal when the [ENTER] key is pressed. (ATT ON
✽ ✽ is displayed in the fluorescent display indicator.)
* The special display using the [ENTER] key is continued
until the next operation is carried out. ( ✽ ✽ : S LEVEL)
When keys other then ENTER are pressed in items 1to
3above, the TUNER ATT is set to OFF and the normal
display appears. The operation corresponding to the key
that has been pressed performed in this case.
(5) When selector is set to positions other than TUNER.
1ENTER and PURE A keys.
The master volume level is selected cyclically, while press-
ing the [ENTER] key.
2AUTO/MONO key.
Selects the mute operation and equalizer cyclically in the
order below for operation display every time this key is
pressed.
*In the operation for except the AUTO key, become pre-
condition equalizer.
*Pre -condition : The equalizer becomes the condition to be
pushed the AUTO key before (include N.B. circuit).
3 BAND and tuning UP/DOWN keys.

and rating fuse(s). To reduce the risk of electric shock, leakage-current or resistance measurements shall be carried out
(exposed parts are acceptably insulated from the supply circuit) before the appliance is returned to the customer.
The DC voltage is an actual reading measured with a high impedance type voltmeter with a cassette loaded at playback
mode. The measurement value may vary depending on the measuring instruments used or on the product. Bias circuit DC
voltage is measured while in the record mode.
