What is Bluetooth wireless 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, 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 standard is an international standard supported by thousands of companies all over the world, and employed by various companies worldwide.

Communication System and Compatible Bluetooth Profiles of this unit

Profile is standardization of the function for each Bluetooth device specification. This unit supports the following Bluetooth version and profiles:

Communication System : Bluetooth Specification version 2.0 + EDR *1

Compatible Bluetooth Profiles:

– A2DP (Advanced Audio Distribution Profile): Transmitting or receiving audio content of high-quality. - AVRCP (Audio Video Remote Control Profile): Controlling A/V equipment; pausing, stopping, starting playback, volume control, etc. - HSP (Headset Profile) *2 : Talking on the phone/Operating the phone. - HFP (Hands-free Profile)*2 : Talking on the phone/Operating the phone by hands-free.

*1 Enhanced Data Rate

*2 When you use a Bluetooth mobile phone supported by both HFP (Hands-free Profile) and HSP (Headset Profile), set to HFP.

Notes

- To be able to use the Bluetooth function, the Bluetooth device to be connected requires the same profile as the unit's. Note also that even if the same profile exists, devices may vary in function depending on their specifications.

- Due to the characteristic of Bluetooth wireless technology, the sound played on this unit is slightly delayed from the sound played on the Bluetooth device during talking on the telephone or listening to the music.

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 (page 26). All pairing information is deleted.

Procedures of pairing

1 Place the Bluetooth 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 POWER button pressed without releasing. The indicator (blue) starts flashing. When both indicators start flashing together again, 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 Bluetooth device to detect this unit.

The list of detected devices appears on the display of the Bluetooth device. This unit is displayed as “DRC-BT15.” If “DRC-BT15” is not displayed, repeat from step 1.

Notes

• For details, refer to the operating instructions supplied with the Bluetooth device.
• 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 Bluetooth device to pairing mode. At this time, if passcode is set besides “0000” on the Bluetooth device, pairing cannot be done with this unit.

4 Select "DRC-BT15" on the display of the Bluetooth device.

5 If Passcode* input is required on the display of a Bluetooth 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 last connected device. Some Bluetooth devices may connect with the unit automatically when pairing is complete.

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 26).

Precautions

On Bluetooth communication

- Bluetooth wireless technology operates within a range of about 10 meters (about 30 feet).

Maximum communication range may vary depending on obstacles (human body, metal, wall, etc.) or electromagnetic environment.

- The antenna is built into the unit as illustrated in the dotted line. The sensitivity of the Bluetooth communication will improve by turning the direction of the built-in antenna to the connected Bluetooth device.

The communication distance shortens when obstacles are between the antenna of the connected device and this unit.

Location of built-in antenna

- The following conditions may affect the sensitivity of Bluetooth communication.

- There is an obstacle such as a human body, metal, or wall between this unit and the Bluetooth device.

- A device using the 2.4 GHz frequency, such as a wireless LAN device, cordless telephone, or microwave oven, is in use near this unit.

- Because Bluetooth devices and wireless LAN (IEEE802.11b/g) use the same frequency, microwave interference may occur, resulting in communication speed deterioration, noise, or invalid connection if this unit is used near a wireless LAN device. In such a case, perform the following.

- Use this unit at least 10 m (about 30 ft) away from the wireless LAN device.

- If this unit is used within 10 m (about 30 ft) of a wireless LAN device, turn off the wireless LAN device.

- Install this unit and the Bluetooth device as near to each other as possible.

- Microwaves emitting from a Bluetooth device may affect the operation of electronic medical devices. Turn off this unit and other Bluetooth devices in the following locations, as it may cause an accident.

- Where inflammable gas is present, in a hospital, train, airplane, or petrol station.

- Near automatic doors or a fire alarm.

- This unit supports security capabilities that comply with the Bluetooth standard to provide a secure connection when Bluetooth wireless technology is used, but security may not be sufficient depending on the settings. Be careful when communicating using Bluetooth wireless technology.

- We do not take any responsibility for the leakage of information during Bluetooth communication.

- Connection with all Bluetooth devices cannot be guaranteed.

- A device featuring Bluetooth function is required to conform to the Bluetooth standard specified by Bluetooth SIG, Inc. and be authenticated.

- Even if the connected device conforms to the above-mentioned Bluetooth standard, some devices may not be connected or work correctly, depending on the features or specifications of the device.

- While talking on the phone hands-free, noise may occur, depending on the device or communication environment.

- Depending on the device to be connected, it may require some time to start communication.

On the supplied AC power adaptor

- Use the AC power adaptor supplied with this unit. Do not use any other AC power adaptor since it may cause the unit to malfunction.
