POLAR 8 1.0

3 Bluetooth
POLAR 8 offers Bluetooth audio streaming, or in other words, wireless
music playback from Bluetooth-enabled players such as smartphones or
tablets. In addition, two POLAR 8 can be paired in stereo via Bluetooth TWS
(True Wireless Stereo) in order to stream music in stereo.
Information: Bluetooth TWS only transmits the audio streaming signal of
the Bluetooth device to the two POLAR 8s. Because of this, microphone or
line signals from one POLAR 8 cannot be transmitted to the other POLAR 8
via Bluetooth – this is only possible via a cable connection.
Before streaming, the Bluetooth device must first be paired with the
POLAR 8. This process, as well as the way in which the Bluetooth connec-
tion works, may vary slightly depending on the Bluetooth device used,
however, in principle, it works as follows:
3.1 Connecting to a Bluetooth device for
Bluetooth audio streaming
To connect the Bluetooth player to POLAR 8, follow the steps below:
1. Press the Pairing button
●
8
to create a Bluetooth connection. During
the pairing time window (120 seconds), the Pairing button flashes
slowly to indicate that a connection can be established.
2. In the Bluetooth menu of your Bluetooth device, select “HK Audio
POLAR 8” (followed by the individual 4-digit ID code of this particular
POLAR 8) to establish the connection.
The Pairing button will light up continuously once the connection has been
successfully established.
If a Bluetooth connection cannot be established within 120 seconds, this is
indicated by rapid flashing at the end of the time window, after which the
pairing process is terminated.
The Pairing button will also flash for 120 seconds if there is no connection
to a connected Bluetooth device (e.g. when leaving the connection radius).
If the Bluetooth device is returned within range within this time, the con-
nection is automatically re-established.
Heads up! If the connection is interrupted for more than 120
seconds, the Bluetooth connection must be re-established manually.
To do this, simply press the POLAR 8 Pairing button briefly.
Heads up! Pressing the Pairing button always activates a new
Bluetooth connection setup and disconnects any existing connection
(including TWS).
3.2 Connecting a second POLAR 8 for Bluetooth TWS
(True Wireless Stereo)
Two POLAR 8 can be paired with each other using Bluetooth TWS, enabling
wireless music playback in stereo. The POLAR 8 connected to the Bluetooth
player receives the stereo signal and plays back the right side. The left side
is forwarded to the second POLAR 8 via Bluetooth.
To pair two POLAR 8 using Bluetooth TWS, follow the steps described
below:
1. Press the TWS Link switch
●
9
of the POLAR 8 that is already con-
nected to the Bluetooth player. The corresponding TWS LED will start
to flash slowly.
2. Press the TWS Link switch
●
9
and then the Pairing button
●
8
of
the second POLAR 8. Its LEDs also start to flash; the Bluetooth TWS
connection to the first POLAR 8 is established
After successfully setting up the connection, the Pairing buttons and the
TWS LEDs of both POLAR 8 will be lit up continuously.
To terminate the Bluetooth TWS connection, press the TWS Link switch(es)
of one or both of the POLAR 8s. The TWS LEDs will go out, the TWS con-
nection will be disconnected ad also no longer established automatically.
As long as both TWS switches are pressed, the two POLAR 8s will auto-
matically establish a Bluetooth TWS connection, even after sitching off and
on again, if they are within range of each other.
Heads up! If the connection with the Bluetooth device is interrupted
for more than 120 seconds, the Bluetooth connection must be re-estab-
lished manually. To do this, simply select the POLAR 8 previously
connected to the Bluetooth device again in the Bluetooth menu of the
Bluetooth device.
If you press the Pairing button on one of the two POLAR 8 instead, any
existing TWS connection between the two POLAR 8 will be disconnected
and must be re-established.
Heads up! Pressing the Pairing button always activates a new
Bluetooth connection setup and disconnects any existing connection,
including the Bluetooth TWS connection between two POLAR 8.
3.3 Changing the Bluetooth player
Press the Pairing button
●
8
of the POLAR 8 connected to the Bluetooth
device to disconnect the currently connected Bluetooth device and connect
another Bluetooth device.
Heads up! Pressing the Pairing button always activates a new
Bluetooth connection setup and disconnects any existing connection,
including the Bluetooth TWS connection between two POLAR 8s.
If two POLAR 8 are in TWS mode, the first POLAR 8 must also be paired
again with the second POLAR 8 via TWS after changing the Bluetooth
device. To do this, press the TWS switches of both POLAR 8 off and back
on again.
3.4 More details about Bluetooth
Automatic connection to Bluetooth devices
After switching POLAR 8 off and on again, it will automatically search for
the last connected Bluetooth device for a period of 120 seconds and estab-
lish a connection if the Bluetooth device is within range. After 120 seconds,
the automatic Bluetooth searching process ends. A new search can be
started at any time by pressing the Pairing button.
Range
POLAR 8 supports Bluetooth 5. When using a Bluetooth 5-enabled device,
ranges of up to 40 m are possible, whilst with devices that do not support
Bluetooth 5, the range is usually up to 10 m. However, the range depends on
various factors such as the quality and transmission power of the Bluetooth
device as well as environmental factors (such as walls obstructing the radio
communication path or even a protective cover over the Bluetooth device).
If the radius of the Bluetooth connection is exceeded, the connection and
thus the audio playback will be interrupted, and the Pairing button will
