CD ADJUSTMENT

1) Cautions on adjustments
In this product the single voltage (3.3 V) is used for the regulator. The reference voltage is the REFO1 (1.65 V) instead of the GND.
If you should mistakenly short the REFO1 with the GND during adjustment, accurate voltage will not be obtained, and the servo’s misoperation will apply excessive shock to the pickup. To avoid such problems:
a. Do not mix up the REFO1 with the GND when connecting the (-) probe of measuring instruments.
Especially on an oscilloscope, avoid connecting the (-) probe for CH1 to the GND.
b. In many cases, measuring instruments have the same potential as that for the (-) probe. Be sure to set the measuring instruments to the floating state.
c. If you have mistakenly connected the REFO1 to the GND, turn off the regulator or the power immediately.
Before mounting and removing filters or leads for adjustment, be sure to turn off the regulator.
For stable circuit operation, keep the mechanism operating for about one minute or more after the regulator is turned on.
In the test mode, any software protections will not work. Avoid applying any mechanical or electrical shock to the mechanism during adjustment.
The RFAGC and RFO signals with a wide frequency range are easy to oscillate. When observing the signals, insert a resistor of 1k ohms in series.
The load and eject operation is not guarantied with the mechanism upside down. If the mechanism is blocked due to mistaken eject operation, reset the product or turn off and on the ACC to restore it.

2) Test mode
This mode is used to adjust the CD mechanism module.
To enter the test mode.
press [4] + [6] > Reset
To exit from the test mode.
Turn off the ACC and back up.
Notes:
a. During ejection, do not press any other keys than the EJECT key until the loaded disc is ejected.
b. If you have pressed the [RIGHT] key or [LEFT] key during focus search, turn off the power immediately to protect the actuator from damage caused by the lens stuck.
c. For the TR jump modes except 100TR, the track jump operation will continue even if the key is released.
d. For the CRG move and 100TR jump modes, the tracking loop will be closed at the same time when the key is released.
e. When the power is turned off and on, the jump mode is reset to the single TR (91), the RF amp gain is set to 0 dB, and the auto-adjustment values are reset to the default settings.

Releasing method:
Press the [SOURCE OFF] button for 1 second.
MICROPHONE AUDIO LOOPBACK
To confirm the state of the internal microphone used when a handsfree function is used, the microphone audio is output from the speaker.
Procedure:
1. Enter the test mode.
2. Press the [SOURCE OFF] button to select the Bluetooth Phone function.
3. On/off of the microphone audio loopback function changes whenever the [ALBUM UP 2] button is pressed (“ALBM” is displayed in the liquid crystal display)

BLUETOOTH FUNCTION CHECKING METHOD USING A CELLULAR PHONE
1. Required Equipment
Set to be tested (DSX-M50BT)
Cellular phone
Bluetooth audio devices
Speaker connection
DC power supply (12 V)
2. Preparation
Confirm the setting of the DSX-M50BT, and note down it.
Press the [CALL] button and rotate the control dial until “PAIRING” appears, then press it, confirm that the Bluetooth signal icon  is flashing.
Turn on the Bluetooth function of the cellular phone.
3. Test Environment
No other Bluetooth device is making a communication in the periphery (within 20 m).
No other DSX-M50BT are supplied with electric power.
There are no two or more wireless LAN access points in the periphery (with 50 m) (one is OK).
The set should be tested in a place such as a meeting room, free from ambient noise.
The speaker at the far end should be in a place such as another meeting room separated acoustically.
Precautions
Beware of the following points when conducting the talking test:
# There is no fault if a talking can be made by adjusting appropriately the volume of the telephone of the other party and the cellular phone connected through the Bluetooth, besides the setup of DSX-M50BT.
# The speaker’s voice will become loud naturally if the periphery is noisy, or become low if quiet (even though the speaker intents to talk on the same volume level).
# The speaker’s voice will become loud naturally if the other party’s voice is loud.

Bluetooth Phone (Hands Free) Function Check
1. Search for this unit from the Bluetooth device (cellular phone), and confirm whether this unit (“Sony Automotive”) is displayed.
2. Search for the distance of this unit and the Bluetooth device (cellular phone) about 5 m apart.
Confirm whether the Bluetooth device (or this unit) is displayed after it searches.
3. Do the pairing of the cellular phone and this unit (input of pass key).
4. Connect the cellular phone with this unit, and confirm the “HF” icon lights.
5. Confirm the connection continues even if the distance of the cellular phone and this unit is separated by about 5 m.
6. Set this unit besides the “BT PHONE” source, and call the cellular phone connected with this unit.
Confirm the automatic change of this unit into “BT PHONE” source, and the change into the screen for incoming calls.
Confirm the ring tone is heard from the speaker.
7. Take a phone call (press the [CALL] button), and start a conversation.
Confirm the other person voice is heard from the front speaker.
Speak toward the microphone of this unit, and confirm whether the other party hears its voice.
Compare the sound quality with a normal set. Confirm that there is no big difference.
8. Turn on ACC from off, and confirm whether this unit connects Bluetooth with the cellular phone again.
Note: Depending on the cellular phone, it might not reconnect automatically when ACC is turned on.

Bluetooth Audio Function Check
Note: Depending on the connecting BT Audio device, track information (e.g. track name, playback time) can be on display.
If the device doesn’t support AVRCP1.3, or, if AVRCP1.3 feature of the device has not been validated with DSX-M50BT; the track information won’t be shown.
Even if there is no track information on display during playback of an AVRCP1.3 device, it is not a failure of DSX-M50BT.
1. Connect the Bluetooth audio device (or cellular phone with Bluetooth audio function) with this unit, and confirm the “Audio Streaming” icon lights.
2. Playback Bluetooth audio. Confirm the sound is emitted from this unit when this unit is switched to “Bluetooth Audio” source.
3. Confirm whether Bluetooth audio can be controlled by operating this unit (the [SEEK+ ], [SEEK– ] and [PAUSE ] buttons operation).
Note: Varies depending on the connected Bluetooth audio device.
