What is pairing?

Bluetooth devices need to be“paired” with each other beforehand.Once Bluetooth devices are paired,there is no need for pairing again,except in the following cases:• Pairing information is deleted

after repair, etc.• This unit is paired with 9 or more

devices.This unit can be paired with up to8 devices; if a new device ispaired after 8 devices have beenpaired, the device whose latestconnection time is the oldestamong the 8 paired devices isreplaced by the new one.

• When recognition of the unit bythe device to be connected isdeleted.

• This unit is initialized.All pairing information is deleted.

Procedures of pairing

1 Place the Bluetoothdevice within 1 m (3 ft)of this unit.

2 Press and hold thePOWER button for7 seconds or more tostandby for pairingwhile the unit is turnedoff.

Notes• After about 3 seconds, power is

turned on and the indicator (blue)and indicator (red) flash togethertwice. Keep the button pressedwithout releasing until bothindicators start flashing together,then release the button. This unitenters into pairing mode.

• If pairing is not established withinabout 5 minutes, pairing mode willbe cancelled and this unit will turnoff. In this case, start over fromstep 1.

3 Perform pairingprocedure on theBluetooth device todetect this unit.The list of detected devicesappears on the display of theBluetooth device. This unit isdisplayed as “DR-BT50.”If “DR-BT50” is not displayed,repeat from step 1.

4 Select “DR-BT50” onthe display of theBluetooth device.

5 If Passcode* input isrequired on the displayof a Bluetooth device,input “0000.”Pairing is complete when theindicator (blue) flashes slowly.The message standing for“Pairing complete” appears onthe display of some Bluetoothdevices.

* Passcode may be called “Passkey,”“PIN code,” “PIN number,” or“Password.”

6 Start the Bluetoothconnection from theBluetooth device.This unit memorizes the deviceas the last connected device.Some Bluetooth devices mayconnect with the unitautomatically when pairing iscomplete.

When pairing with aBluetooth device thatcannot display a list ofdetected devices or thathas no displayYou may pair the device by settingboth this unit and the Bluetoothdevice to pairing mode. For details,refer to the operating instructionssupplied with the Bluetooth device.

Tips• To pair with other Bluetooth devices,

repeat steps 1 to 5 for each device.• To delete all pairing information, see
