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.
