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
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)*: Talking on the
phone/Operating the phone.
– HFP (Hands-free Profile)*: Talking on
the phone/Operating the phone by
hands-free.
* When you use a Bluetooth mobile
phone supported by both HFP (Handsfree 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.

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 “DR-BT22” on
the display of the
Bluetooth device.
5 If Passcode* input is

“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

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 (person,
metal, wall, etc.) or electromagnetic
environment.
• The aerial of this unit is built into the
right unit as illustrated in the dotted
line. The sensitivity of Bluetooth
communication will improve by placing
a connected Bluetooth device on your
right side.
The communication distance shortens
when the obstacles are between the
aerial of the connected device and this
unit.
Location of
built-in aerial
• The following conditions may affect the
sensitivity of Bluetooth communication.
– There is an obstacle such as a person,
metal, or wall between this unit and
Bluetooth device.
– A device using 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 and resulting in communication
speed deterioration, noise, or invalid
connection if this unit is used near a
wireless LAN device. In such as case,
perform the following.
– Use this unit at least 10 m (about
30 ft) away from the wireless LAN
device.
22
– 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 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 a petrol
