TX-NR1010/3010/5010/ DTR-70.4
OPERATION CHECK-1
1.OPERATION CHECK(1/3)
1-1. OPERATIONS OF SPEAKER RELAYS
The relay shall be ON about 10 seconds after POWER is ON and shall be OFF immediately after POWER is OFF.
1-2. OPERATIONS OF VOLTAGE-DETECTION PROTECTORS.
See “OPERATION CHECK-4, -6” for TEST MODE operation.
NOTE: Don't connect load nor short speaker terminals.
(How to check in test mode)
a. Change the state to "TEST-4-24".
b. It tests by being automatic in order of TEST4-24(FL+) → 25(FR-) → 26(C+) → 27(SL-) → 28(SR+) → 29(SBL-)
→ 30(SBR+) → 31(FHL-) → 32(FHR+). If TEST-4-32 is ok, it becomes the display of "TEST-4-42."
c. It will complete, if displayed on FL TUBE as "TEST-4-42."
1-3. OPERATIONS OF CURRENT-DETECTION PROTECTORS
See “OPERATION CHECK-4, -6” for TEST MODE operation.
a. Change the state to "TEST 4-42".
Even if you connect 3-ohm load for every channel of L, R, C, SL, SR, SBL,SBR,FHL and FHRch, a relay should not cut off.
b. If 1-ohm load is connected for every channel of L,R,C,SL,SR,SBL,SBR,FHL and FHRch, a relay should hold the state of ON.
1-4. CONFIRMATION OF RDS (RADIO DATA SYSTEM) OPERATION
(applies to MMA/MMP/MMQ/MMR Type. )
a. Input 98MHz,30dBμ signal modurated with RDS data.
b. When a PS information is received, the name of the station "RDS TEST" shall be displayed within 2 seconds instead of the frequency.
1-5. CONFIRMATION OF HEAD PHONE OPERATION.
Confirm the Listening Mode is automatically switched to "STEREO" mode when headphones plug is inserted into the PHONES jack.
1-6. CONFIRMATION OF 12V TRIGGER OPERATIONS .
See “OPERATION CHECK-4, -5” for TEST MODE operation.
a. After checking that there is no output from 12V TRIGGER Z2 terminal,it checks that there is an output
of 12V±10%/150mA after 2 seconds switched the "TEST3-01". (expect TX-NR1010MJJ/5010MJJ Model)
b. After checking that there is no output from 12V TRIGGER Z3 terminal,it checks that there is an output
of 12V±10%/25mA after 2 seconds switched the "TEST3-01". (expect TX-NR1010MJJ/5010MJJ Model)
c. After checking that there is no output from 12V TRIGGER A terminal,it checks that
there is an output of 12V±10%/150mA after 2 seconds switched the "TEST2-08". (Integra model ONLY)
d. After checking that there is no output from 12V TRIGGER B terminal,it checks that
there is an output of 12V±10%/25mA after 2 seconds switched the "TEST2-09".(Integra model ONLY)
e. After checking that there is no output from 12V TRIGGER C terminal,it checks that
there is an output of 12V±10%/25mA after 2 seconds switched the "TEST2-10".(Integra model ONLY)
1-7. CONFIRMATION OF OUTPUT VOLTAGE SENSOR AND THERMAL PROTECTOPERATION.
See “OPERATION CHECK-4, -6” for TEST MODE operation.
a. Set the TEST MODE to "TEST 4-43" and "TEST 4-44" and "TEST 4-45".
Confirm to lit "FM STEREO" on FL display..
b. Push STANDBY/ON button while pushing down DISPLAY button to display CPU PROGRAM version.
Push TONE button while displaying CPU PROGRAM version to display value of temparature sensor.
Confirm outside temperature ±20C is displayed immediately after energizing.
Note that the error margin is caused by the rise of the temperature of the heat sink when time passes.
No singal condition (Ex. Display)
V:>00 F:x S:H
AT:020 DT:020
V: Output signal level
F: FAN condition
S: Amplifier power supply voltage condition
AT: Temparature sensor of Amplifier(Left or Right)
DT: Temparature sensor of HDMI PWB
