1. SERVICE PRECAUTIONS
1.1 SERVICE PRECAUTIONS
A
1. You should conform to the regulations governing the product (safety, radio and noise, and other regulations),
and should keep the safety during servicing by following the safety instructions described in this manual.
2. Be careful in handling ICs. Some ICs such as MOS type are so fragile that they can be damaged by electrostatic
induction.
3. Before disassembling the unit, be sure to turn off the power. Unplugging and plugging the connectors during
power-on mode may damage the ICs inside the unit.
4. To protect the pickup unit from electrostatic discharge during servicing, take an appropriate treatment
(shorting-solder) by referring to "the DISASSEMBLY" .
5. After replacing the pickup unit, be sure to skew adjustment.
6. When a flash ROM needs to be replaced by service, do not replace an IC but a core unit (as no encryption key is
B
written in a flash alone).
7. During disassembly, be sure to turn the power off since an internal IC might be destroyed when a connector
is plugged or unplugged.
8. Countermeasures to user complaints on iPhone/iPod touch lip synchronization
When a video is replayed, the video and audio may be out of synchronization depending on the connected
iPod or iPhone.
If it is annoying, perform the following operation.
However, this operation will slightly deteriorate the sound quality of the iPod source.
Also, it will disable the ASR function when the iPod source is used.
[Default]
C
Audio digital mode
[Switching procedure]
Press MODE and EJECT and turn on Accessory simultaneously
The above switches the "Audio digital mode" to the "Audio analog mode".
When the mode is switching, the BEEP1 sound will be heard.
[Supplement]
• The mode switching operation can only switch the "Audio digital mode" to the "Audio analog mode".
(The BEEP1 sound will be heard every time.)
• No indication of the mode is provided.
D
[Resetting the mode]
Reset or BackUP OFF
The above resets the mode to the "Audio digital mode".
Verification method
If the voice is not heard when a movie is played with the AUX jack unplugged, the voice has been switched to analog.
* Initially, AUDIO sound is output with the AUX jack unplugged as it comes in via USB (digital).
9. Recautions for AEQ measurement
E
If the microphone is not connected securely, the microphone input signals may become inaccurate and an
error message "Plug the supplied microphone securely into the jack" may appear due to the measurement failure.
10. EJECT LOCK MODE for DVD mechanism
How to enter : Press RESET while pressing [FORWARD] and [EJECT] keys together.
How to exit : Same procedure to enter this mode.
11. When EEPROM is initialized, eject lock may be enabled. Please cancel eject lock in this case.
12. The connector in the monitor unit CN5002:CKS6008 is the connector with both contacts.
If the flexible board is inserted reversely, unintended connection is made and it may cause a breaking of fuse or
destruction of part.
Do not insert it reversely.
13. The part listed below is difficult to replace as a discrete component part.
When the part listed in the table is defective, replace whole Assy.
