DEBUG MODE-1

AUDIO DEBUG MODE-1/5

TX-SR333/ HT-R393/ HT-RC630

The operations of DSP and DIR etc are able to checked by the information displayed on FL in this debug mode.
This information will help to analysing digital audio no sound trouble,

To set in Debug mode

1. Press twice the ON/ STANDBY key while pressing the DISPLAY key.

e.g.

M1.03/14307ALN*

The version number of Microprocessor is displayed
only for 3 seconds

2 Press + (TONE) button while the version number of microprocessor is displayed.

e.g.

N1 02/14210ALA _ The version number of DSP is displayed

3. Press DISPLAY button while the version number of DSP is displayed.

e.g.

0A0002. :00

OPERATION CHECK-3

CONFIRMATION OF VOLTAGE-DETECTION PROTECTORS.

Don't connect load nor short speaker terminals.

1. Do the following operation.
1-1. set the volume level to 25.
1-2. [TV/CD] + [ON/STANDBY] a [BD/DVD]
1-3. now; +]
to the following test mode.
TEST 1-01
2. AVR automatically tests in the following test sequence. And if it is all OK, Wi-Fi test will begin.
Test sequence
(FL+) ~> (FR-) a (0+) a (SL-) 4, (SR+)4> (SW+) SW+ : HT-R393 only
3. If FL tube displays Wi-Fi check mode then voltage-detection protectors test will be completed.

CONFIRMATION OF UPDATE ROUTE.
1. Do the following operation.
1-1. set the volume level to 25.
1-2. [TV/CD] + [ON/STANDBY] a [BD/DVD]

1-3. new; +1
to the following test mode.
TEST 1-01

2.0nce the above mentioned test mode is entered, voltage-detection protectors function is checked automatically first, then update
route check will begin.
If the result of update route check is no problem then Wi-Fi check will begin. If the result is NG then NG message will be shown on
the FL tube.

3. If FL tube displays Wi-Fi check mode then voltage-detection protectors test and update route check are passed.

CONFIRMATION OF Wi-Fi CONNECTION

1. Setting Wi-Fi routers.
2. Do the following operation.

2-1. set the volume level to 25.

2-2. [TV/CD] + [ON/STANDBY] 4» [BD/DVD]

2-3. [TONE +1

to the following test mode.

TEST 1-01

3. Once the above mentioned test mode is entered, voltage-detection protectors function is checked automatically first, then update
route check will begin and then Wi-Fi check will begin.
In Wi-Fi check mode, it connects an access point automatically. Wi-Fi LED flashes during connection.
4. If connection is completed and IP address is successfully acquired, Wi-Fi LED turning lights off and the value of FiSSI to an access
point is displayed in dBm.
If the connection is failed, NG is displayed.

e. . _ , u
g 01-2 51570, M Max value of RSSI is -45dB.(Display of FL is -45d.)
SSID No FiSSl(dbm) Time Counter

If the connection is failed, exit the idling timer mode by pressing the TV/CD button and please try again from step 1.
In case value of RSSI level isn't showed on the FL tube at all past 4 minutes in this timer mode, judge as NG.

COMFIRMATION OF USB
1. Connect USB memory or USB storage to AVFt front USB port.

2. Change selector to USB. After FL tube showed USB device name, press Enter key twice, then confirm signals form front
L/Ft or Headphone.
Change volume as necessary.
