When the AC power adaptor is connected to an AC outlet, charging starts.

Tip

If the AC power adaptor is connected to an AC outlet while the unit is turned on, the unit will be turned off automatically.

2 Make sure that indicator (red) lights up while charging.

Charging is completed in about 3 hours* and the indicator (red) goes off automatically.

• Time required for empty battery to recharge.

Caution

If this unit detects a problem while charging, the indicator (red) may turn off, although charging is not complete.

Check for the following causes:

• Ambient temperature exceeds the range of 0^ - 40^ (32°F - 104°F).
• There is a problem with the battery.

In this case, charge again within the above-mentioned temperature range. If the problem persists, consult your nearest Sony dealer.

Notes

• If the battery is not used for a long time, battery may be quickly depleted, however, after a few recharges, battery life will improve.
• If the life of the built-in rechargeable battery drops to half the normal length, the battery should be replaced. Consult your nearest Sony dealer for replacement of the rechargeable battery.
• Avoid exposure to temperature extremes, direct sunlight, moisture, sand, dust or mechanical shock. Never leave in a car parked in the sun.
• Use only the supplied AC power adaptor. Do not use any other AC power adaptor.

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 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 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 Bluetooth device to detect this unit.

The list of detected devices appears on the display of the Bluetooth device. This unit is displayed as "DR-BT50." If "DR-BT50" is not displayed, repeat from step 1.

4 Select "DR-BT50" 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.

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. For details, refer to the operating instructions supplied with the Bluetooth device.

Tips

• To pair with other Bluetooth devices, repeat steps 1 to 5 for each device.

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 as 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.
