To switch the audio output destination
between the Bluetooth headphones
and the headphones connected to the
linear PCM recorder
While a Bluetooth connection is established,
no sound is output from the headphones
connected to the  (headphones) jack on the
linear PCM recorder.
To use the connected headphones for
listening, disconnect the Bluetooth
connection.
Note
• The device registration (pairing) information is
cleared in the following cases. You need to register
(pair) the device with your linear PCM recorder once
again.
– The settings on either or both devices are reset
to the default settings, for example, due to
initialization.
– The device registration (pairing) information is
deleted, for example, during the course of a repair
service.
If the device registration (pairing) is deleted from
the linear PCM recorder but the Bluetooth audio
device still has the device registration (pairing)
information of the linear PCM recorder, delete the
information and make device registration (pairing)
once again.
• While the Bluetooth function is turned on, the
battery wears quickly to a large extent.
• Depending on the Bluetooth audio device
connected with your linear PCM recorder, the
communication environment, or the ambient
conditions, you may hear noises or audio dropouts.
• Bluetooth wireless technology allows connection at
distance of up to about 10 m (33 ft). However, the
effective range may vary depending on obstructions
(people, metals, wall, etc.) or signal status.
• The linear PCM recorder supports A2DP (Advanced
Audio Distribution Profile) and AVRCP (Audio/Video
Remote Control Profile) as the Bluetooth profile. To
establish a Bluetooth connection with a Bluetooth
device from the linear PCM recorder, the Bluetooth
device must support A2DP. On a Bluetooth audio
device that supports AVRCP, such as Bluetooth
headphones, you can perform basic operations of
the linear PCM recorder.
• If passkey* entry is prompted on the display window
of your linear PCM recorder in the course of device
registration (pairing), find out the passkey for the
Bluetooth audio device and enter the passkey.
• You can register (pair) a single Bluetooth audio
device with your linear PCM recorder at a time. To
register (pair) multiple devices, perform the above
procedure from step 1 for each device.
• If the same Bluetooth audio device name is
displayed multiple times, check the device that you
want to register (pair) for its BD address. To find
out the BD address for the Bluetooth audio device,
refer to the operating instructions supplied with
the device.
• You can also establish/disconnect the Bluetooth
connection by selecting " Bluetooth" 
"Bluetooth ON/OFF."
* The passkey may also be called "passcode," "PIN
code," "PIN number," or "password." The passkey for
the linear PCM recorder is "0000."
To find out the passkey for the Bluetooth audio
device, refer to the operation instructions supplied
with the device.
Establishing a Bluetooth connection
with the one-touch operation (NFC
connection)
You can register (pair) an NFC-compatible
Bluetooth audio device and establish a
Bluetooth connection with your linear PCM
recorder by putting the recorder onto the
device.
1 If the Bluetooth audio device as the NFC
switch, turn on the switch.
2 Put the linear PCM recorder onto the
Bluetooth audio device.
Align the mark on the linear PCM
recorder with the mark on the Bluetooth
audio device and keep them touched
until an instruction appears on the display
window of the linear PCM recorder.
