Bluetooth mode

The Bluetooth mode on your radio allows you to play audio, play sound from

video ﬁ les and stream music from Bluetooth capable devices such as your

moblie phone, computer, tablet etc. through your radio's loudspeakers.

'Bluetooth pairing' occurs when two Bluetooth enabled devices agree to

establish a connection and communicate with each other.

When a Bluetooth enabled device such as your Blutune 50 radio is in a

'discoverable' state other Bluetooth devices can detect, pair with or connect to it.

Your radio will ﬂ ash its Bluetooth indicator light when it is discoverable or

when it is trying to connect to a previously paired Bluetooth device. When a

device is paired with and connects to your radio, the Bluetooth indicator light

on the radio will remain lit.

Bluetooth connectivity performance may vary depending on the connected

Bluetooth devices. Please refer to the Bluetooth capabilities of your device

before connecting to your radio. All features may not be supported on some

paired Bluetooth devices.

A Bluetooth connection can provide a link for audio up to a distance of

approximately ten metres. When pairing two Bluetooth enabled devices, for

convenience, we recommend they should be no more than 2 to 3 metres apart.

The presence of other functioning Bluetooth devices during connection may

lead to operational difﬁ culties. Bluetooth is a short-range radio communication

system and generally Bluetooth devices can communicate with each other

clearly within a regular sized room or ofﬁ ce. The reliability of a Bluetooth

connection between different rooms will greatly depend upon the construction

of the room and walls etc. Bluetooth communication range may be substantially

reduced if the signal passes through a solid object.

Human bodies, brick and concrete walls, heavy furniture or bookcases will

all reduce the operational range of your Bluetooth devices to a greater or

lesser extent. Glass, dry-wall or wood paneled walls and ofﬁ ce partitions may

have a less severe but noticeable effect. Metal pipes, foil-lined plasterboard,

metal window frames and domestic wiring can also have an effect. You

should position your Bluetooth devices closer to each other if you observe

communication difﬁ culties.

WiFi networks and cordless phones generally use similar radio frequencies to

Bluetooth and may interfere with one another. If any interference is noticed,

then try relocating the radio or one of the other devices.

Some Bluetooth devices may require a 'Passkey' (an authentication key) in

order to establish a link between devices. A passkey is similar to a password,

although you only need to use the passkey once to establish a link. If your

device asks for a passkey to be able to pair with your radio then enter a code

of 0000 (four zeroes).

The Bluetooth capabilities of your radio enable it to receive audio from many

Bluetooth capable devices including mobile phones, personal computers and

PDAs. Only one Bluetooth device can be connected to your radio at a time.

It supports the following Bluetooth proﬁ les and functionality.

Your radio supports A2DP (Advanced Audio Distribution Proﬁ le) which is

a stereo audio connection that streams stereo music from PCs, mobile

phones etc,

Your radio supports AVRCP (Audio Video Remote Control Proﬁ le) which

allows your radio to control music playback from the connected device.

Note: Some mobile phones may temporarily disconnect from your radio when

you make or receive calls. Some devices may temporarily mute their Bluetooth

audio streaming when they receive text messages, emails or for other reasons

unrelated to audio streaming. Such behaviour is a function of the connected

device and does not indicate a fault with your radio.
