Pairing

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 to 8 devices; if a new device is paired after 8 devices have been paired, the device whose latest connection time is the oldest among the 8 paired devices is replaced by the new one.
• When recognition of the unit by the device to be connected is deleted.
• This unit is initialized. All pairing information is deleted.

Procedures of pairing

1 Place the connecting device within 1 m (3 ft) of this unit.
2 Press and hold the POWER button for 7 seconds or more to standby for pairing while the unit is turned off.

Notes

• After about 3 seconds, power is turned on and the indicator (blue) and indicator (red) flash together twice. Keep the button pressed without releasing until both indicators start flashing together, then release the button. This unit enters into pairing mode.
- If pairing is not established within about 5 minutes, pairing mode will be cancelled and this unit will turn off. In this case, start over from step 1.

3 Perform pairing procedure on the connecting device to detect this unit.

The list of detected devices appears on the display of the connecting device. This unit is displayed as “DR-BT20NX.” If “DR-BT20NX” is not displayed, repeat from step 1.

4 Select "DR-BT20NX" on the display of the connecting device.

5 If Passcode* input is required on the display of a connecting device, input "0000."

Pairing is complete when the indicator (blue) flashes slowly. The message standing for “Pairing complete” appears on the display of some BLUETOOTH devices.

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

6 Start the BLUETOOTH connection from the BLUETOOTH device.

This unit memorizes the device as the latest connected device. Some BLUETOOTH devices may connect with the unit automatically when pairing is complete.

When pairing with a BLUETOOTH device that cannot display a list of detected devices or that has no display

You may pair the device by setting both this unit and the connecting device to pairing mode. For details, refer to the operating instructions supplied with the connecting device.

Tips

- To pair with other BLUETOOTH devices, repeat steps 1 to 5 for each device.

- To delete all pairing information, see “Initializing the unit” (page 25).

Wearing the headset

Place the neck strap around your neck, then wear the earpiece marked Ⓡ in your right ear and the one marked Ⓛ in your left ear. The neck strap prevents the earpieces from dropping.

①The right-side connector will uncouple for safety if excessive pressure is applied.
②You can conveniently turn the left-side connector (turn lock) in the direction of the arrow and remove it when putting a strap around your neck.
③When you remove the earpieces to wear around your neck, slide the cord adjusters toward the earpieces to prevent the cord from tangling.

How to install the earbuds correctly

If the earbuds do not fit your ears correctly, low-bass sound may not be heard. To enjoy better sound quality, adjust the earbuds position to sit on your ears comfortably or push them into the inside of your ears so that they fit your ears snugly. If the earbuds do not fit your ears, try ones of other size.

How to use the holder

Store the earpieces. It prevents the cord from tangling if you store the earbuds.

What is BLUETOOTH technology?

BLUETOOTH wireless technology is a short-range wireless technology that enables wireless data communication between digital devices, such as a computer or digital camera. BLUETOOTH wireless technology operates within a range of about 10 meters (about 30 feet).

Connecting two devices as necessary is common, but some devices can be connected to multiple devices at the same time. You do not need to use a cable for connection since BLUETOOTH technology is a wireless technology, nor is it necessary for the devices to face one another, such is the case with infrared technology. For example, you can use such a device in a bag or pocket.

BLUETOOTH technology is an international standard supported by thousands of companies all over the world, and employed by various companies worldwide.
