BLUETOOTH FUNCTION CHECKING METHOD USING A CELLULAR PHONE
Required Equipment
# Set to be tested (WX-GT90BT/GT90BTE/GT99BT), external microphone of attachment
# Cellular phone (Recommended SEMC W880 or W910i, or select 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)
Preparation
# Confirm the setting of the WX-GT90BT/GT90BTE/GT99BT, and note down it.
# Press the [CALL] button and rotate the control dial until “SET PAIRING” appears, then press it, confirm that the Bluetooth signal icon is flashing.
# Turn on the Bluetooth function of the cellular phone.
Test Environment
# No other Bluetooth device is making a communication in the periphery (within 20 m).
# No other WX-GT90BT/GT90BTE/GT99BT 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.

5. 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 WX-GT90BT/GT90BTE/GT99BT.
# 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
Note 1: Depending on the connecting device, Signal-strength/Batteryremaining 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 WX-GT90BT/GT90BTE/GT99BT.
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 passkey).
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 front speaker.
7. Take a phone call (press the [CALL ] button), and start a conversation.
Confirm the other person voice is heard from the speaker. Speak toward an external microphone at the following condition, and confirm the other party hears its voice (An external microphone is connected). 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 set connects Bluetooth with the cellular phone again. Note 2: Depending on the cellular phone, it might not reconnect automatically.

Bluetooth Audio Function Check
Note 1: 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 WX-GT90BT/GT- 90BTE/GT99BT, 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 WX-GT90BT/GT- 90BTE/GT99BT.
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+ Forward ], [Rewind SEEK–] and [PAUSE 6] buttons operation).
Note 2: Varies depending on the connected Bluetooth audio device.
What to Do after Checking
# After checking, select “BT INIT” from the menu list of this unit to execute initialization. (Connected device information is deleted)
