OPERATION CHECK-1
1.OPERATION CHECK(1/2)
1-1. OPERATIONS OF VOLTAGE-DETECTION PROTECTORS.
See "OPERATION CHECK-3, -5" for TEST MODE operation.
NOTE: Don't connect load nor short speaker terminals.
a. Change the state to "TEST-4-21".
b. It tests by being automatic in order of TEST4-21(FL+) → 22(FR-) → 23(C+) → 24(SL-)
→ 25(SR+) → ( 26(SBL-) → 27(SBR+) ). It becomes the display of "TEST-4-35."
c. It will complete, if displayed on FL TUBE as "TEST-4-35."
d. Check operation of voltage-detection of subwoofer channnel. (HT-R391/358 only)
Change the state to "TEST-1-00".
The speaker relay is OFF immediately after D.C. +1.5v
The same as above when D.C. -1.5v
NOTE1: Limit time to apply voltage is 0.5-1.0 seconds each channel.
When protection operation does not occur at once, try several times.
NOTE2: Don't connect load nor short speaker terminals.
NOTE3: The relay shall recover in one second in "TEST-1-00". So it shall not be hold OFF.
1-2. OPERATIONS OF CURRENT-DETECTION PROTECTORS
See "OPERATION CHECK-3, -4" for TEST MODE operation.
a. Change the state to "TEST-4-35".
Even if you connect 3-ohm load for every channel of L, R, C, SL, SR, SBL,SBR and SWch, a relay should not cut off.
If 1-ohm load is connected for every channel of L, R, C, SL, SR,SBL,SBR and SWch, a relay should hold the state of ON.
1-3. CONFIRMATION OF RDS (RADIO DATA SYSTEM) OPERATION (Applied to MPP/MPB 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.
1-4. CONFIRMATION OF HEAD PHONE OPERATION.
Confirm the Listening Mode is automatically switched to "STEREO" mode when headphones plug is inserted into the PHONES jack.
1-5. COMFIRMATION OF USB(Except of HT-R358)
See "OPERATION CHECK-3, -4" for TEST MODE operation.
a. Connect ipod to AVR USB port.
b. When set to TEST-3-10, confirm that the display of AVR change "connecting" to "press Push [MODE] button ...." or "iPod"
after few seconds.
The following iPod models can be used for inspection.(The above-mentioned operation is not done excluding the following items.)
iPod classic, 3G nano, 4G nano, 5G nano
1-6. CONFIRMATION OF OUTPUT SENSOR AND THERMAL SENSER.
See "OPERATION CHECK-3, -5" for TEST MODE operation.
a. Set the TEST MODE to "TEST-4-36" and "TEST-4-37".
After light "FM STEREO" on FL display, the relays RL691/692 is OFF and "FM STEREO"is off .(TEST4-37 is only for HT-R591.)
b. Push ON/Standby 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.
