Confirmation Of Voltage-Detection Protectors; Confirmation Of Update Route; Confirmation Of W-Fi Connection; Confirmation Of Zone2 Dac Route - Onkyo TX-NR838 Service Manual

OPERATION CHECK-3

CONFIRMATION OF VOLTAGE-DETECTION PROTECTORS.

<NOTE>
Don't connect load nor short speaker terminals.
1. Do the following operation.
1-1. set the volume level to 25(TX-NR636, DTR-30.6) or 30(TX-NR737, 838, DTR-40, 50.5).
1-2. [TV/CD] + [ON/STANDBY] → [BD/DVD]
1-3. [TONE +]
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-) → (C+) → (SL-) → (SR+) → (SBL-) → (SBR+)
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(TX-NR636, DTR-30.6) or 30(TX-NR737, 838, DTR-40, 50.5).
1-2. [TV/CD] + [ON/STANDBY] → [BD/DVD]
1-3. [TONE +]
to the following test mode.
TEST 1-01
2. Once 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.
Detail of NG number of F/W update route test is as below.
1 N/A
2 VIDEO - OSD
3 DA830 - KG2H
4 VIDEO - HDCP TX
5 VIDEO - HDCP RX
CONFIRMATION OF Wi-Fi CONNECTION
1. Setting Wi-Fi routers.
2. set 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 RSSI to an access
point is displayed in dBm.
If the connection is failed, NG is displayed.
e.g.
SSID No
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.
The sound from USB flash device is output from Zone2 PREOUT or Zone2 LINEOUT via Zone2 DAC.

CONFIRMATION OF ZONE2 DAC ROUTE

1. Connect USB memory or USB storage to AVR front USB port.
2. set the following test mode.
TEST 1-01
3. After being displayed Wi-Fi RSSI level, it will play back wave file from USB storage.
4. Check the wave form that appears L+R and R alternately from the following output terminal.
ZONE2 LINE OUT
Output terminal :
Wi-Fi LED is turn on in Zone2 DAC check mode.
TX-NR636/ 737/ 838/ HT-RC660/ HT-R993/ DTR-30.6/ 40.6/ 50.6
