3.  Solder three terminals of the jack.

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 fail-

ures of MEX-GS600BT.

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

and confi rm whether this unit (“Sony Automotive”) is dis-
played.

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

(cellular phone) about 5 m apart.

 Confi rm whether the Bluetooth device (or this unit) is dis-

played after it searches.

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

passkey).

4.  Connect the cellular phone with this unit, and confi rm  the 

“HF” icon ( ) lights.

5. Confi rm 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 cel-

lular phone connected with this unit.

BLUETOOTH  FUNCTION  CHECKING  METHOD  USING  
A  CELLULAR  PHONE
1. Required Equipment
•  Set to be tested (MEX-GS600BT), external microphone of at-

tachment

•  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-GS600BT, and note down it.
•  Press the [CALL

 

] button and rotate the control dial until 

“SET PAIRING” appears, then press it, confi rm that the Blue-
tooth 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-GS600BT 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-GS600BT 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-GS600BT.

•  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.

This section is extracted 
from instruction manual.

Be sure to install this unit in the dashboard of the car as 
the rear side of the unit becomes hot during use.

This unit is designed for negative ground (earth) 12 V 
DC operation only.
Do not get the leads under a screw, or caught in moving 
parts (e.g. seat railing).
Before making connections, turn the car ignition off to 
avoid short circuits.
Connect the yellow and red power supply leads only 
after all other leads have been connected.
Run all ground (earth) leads to a common ground 
(earth) point.
Be sure to insulate any loose unconnected leads with 
electrical tape for safety.
The use of optical instruments with this product will 
increase eye hazard.

When connecting this unit in combination with other 
stereo components, the connected car circuit’s rating 
must be higher than the sum of each component’s fuse.
When no car circuits are rated high enough, connect the 
unit directly to the battery.

For details on the setting for the connection, see the 
supplied Operating Instruction.

Cet appareil est exclusivement conçu pour fonctionner 
sur une tension de 12 V CC avec masse négative.
Évitez de fixer des vis sur les câbles ou de coincer ceux-ci 
dans des pièces mobiles (par exemple, armature de siège).
Avant d’effectuer les raccordements, coupez le moteur 
pour éviter un court-circuit.
Raccordez les câbles d’alimentation jaune et rouge

ruban isolant tout câble libre non raccordé.
L’utilisation d’instruments optiques avec ce produit 
augmente les risques pour les yeux.

Lorsque cet appareil est raccordé à d’autres éléments 
stéréo, la valeur nominale du circuit de la voiture 
raccordé doit être supérieure à la somme des fusibles de 
chaque élément.
Si aucun circuit de la voiture n’est assez puissant, 
raccordez directement l’appareil à la batterie.
