BLUETOOTH FUNCTION CHECKING METHOD USING

A CELLULAR PHONE

1. Required Equipment

•

Set to be tested (MEX-BT39UW/BT3900U/BT3950U), exter-

nal microphone of attachment (XA-MC10) if necessary

•

Cellular phone (Recommended SEMC W880 or W910i, or se-

lect from connectable cellular phones list)

•

Bluetooth audio devices (SONY NWZ-A826, or select from

connectable cellular phones/audio devices list)

•

Speaker connection (at least Front L/R ch)

•

DC power supply (12 V)

2. Preparation

•

Conﬁ rm the setting of the MEX-BT39UW/BT3900U/

BT3950U, and notate it.

•

Press and hold the BLUETOOTH button and conﬁ rm that the

Bluetooth signal icon ( ) is ﬂ ashing.

•

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 MEX-BT39UW/BT3900U/BT3950U 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.

4. Setting

Install the MEX-BT39UW/BT3900U/BT3950U on the desktop.

5. Precautions

Beware of the following points when conducting the

talking test:

•

There is no fault if a talking can be made by adjusting appro-

priately the volume of the telephone of the other party and the

cellular phone connected through the Bluetooth, besides the

setup of MEX-BT39UW/BT3900U/BT3950U.

•

The speaker's voice will become loud naturally if the periph-

ery 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.

6. Bluetooth Phone (Hands Free) Function Check

Note: Depending on the connecting device, Signal-strength/Battery-re-

maining indications might not be displayed.

Or, depending on the connecting device, the levels of indications are

shown incorrectly.

Even if you see no indications or wrong indications, they are not

failures of MEX-BT39UW/BT3900U/BT3950U.

1. Search for this set from the Bluetooth device (cellular phone),

and conﬁ rm whether this set ("Sony Automotive") is dis-

played.

2. Search for the distance of this set and the Bluetooth device

(cellular phone) about 5 m apart.

Conﬁ rm whether the Bluetooth device (or this set) is displayed

after it searches.

3. Do the pairing of the cellular phone and this set (input of pass

code).

4. Connect the cellular phone with this set, and conﬁ rm the "HF"

icon lights.

5. Conﬁ rm the connection continues even if the distance of the

cellular phone and this set is separated by about 5 m.

6. Set this set besides the "BT PHONE" source, and call the cel-

lular phone connected with this set.

Conﬁ rm the automatic change of this set into "BT PHONE"

source, and the change into the screen for incoming calls.

Conﬁ rm the ring tone is heard from the speaker.

7. Take a phone call (press the encoder switch), and start a con-

versation.

Conﬁ rm the other person voice is heard from the speaker.

Speak toward the microphone of this set, and conﬁ rm whether

the other party hears its voice (At the external microphone

noncontact).

Compare the sound quality with a normal set. Conﬁ rm that

there is no big difference.

8. Speak toward an external microphone at the following condi-

tion, and conﬁ rm the other party hears its voice.

•

An external microphone is connected.

9. Turn on ACC from off, and conﬁ rm whether this set connects

Bluetooth with the cellular phone again.

Note: Depending on the cellular phone, it might not reconnect automati-

cally when ACC is turned on.

7. 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 MEX-BT39UW/BT3900U/

BT3950U;

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 MEX-BT39UW/

BT3900U/BT3950U.

1. Connect the Bluetooth audio device (or cellular phone with

Bluetooth audio function) with this set, and conﬁ rm the "Au-

dio Streaming" icon lights.

2. Playback Bluetooth audio. Conﬁ rm the sound is emitted from

this set when this set is switched to "Bluetooth Audio" source.

3. Conﬁ rm whether Bluetooth audio can be controlled by operat-

ing this set (the Multi way encoder left/right, [PAUSE] keys

operation).

Note: Varies depending on the connected Bluetooth audio device.

8. What to Do after Checking

•

After checking, select "BT INIT" from the menu list of this set
