Speaker output: the Module provides a stereo audio output consisting in left and right channels.
External audio input: the Module includes an external audio input (3,5mm jack). When the user inserts a jack the audio output switches to the signal from the external audio source (red led) and overrides the Bluetooth mode.
Operating Key: the Module is provided with a key for operating the Bluetooth mode.
Led for signaling: the led color for signaling the status of the Module
is as follows:
Blue fl ashing led = waiting for pairing and connecting with the Bluetooth
device
Blue led = Module is connected to the Bluetooth device
Red led = An external audio input has been inserted
Max volume limit switch: the module have a back switch with 2 positions
to select the maximum volume allowed in normal operation.
This limit will be defined by the installer during the installation.
Mono/stereo switch: the module has a back switch with 1 position to allow the
installer to select the mono or stereo audio output.
Audio line output: the module provides an stereo line output for our Audio
Control (ref. 092X4) or our Auxiliary Amplifi er (ref. 13204).
The level of the line output and the audio channel will be determinated by the
the device paired/connected and will not be affected by the volume limit and
stereo/mono jumpers.
Bluetooth ID: each Module is identifi ed as KINGBT-XXXX where XXXX is a serial number which permits the user to identify different Modules that can co-exist in the same installation. In this way, the user can choose from his Bluetooth device the Module with which he wishes to stream his music.

Operation
Before commencing any pairing we recommend that you check that your Bluetooth
device has A2DP/AVRCP profiles. In addition, the pairing process can vary
between manufacturers. Please read carefully your Bluetooth device user manual
beforehand. For a successful pairing make sure the Bluetooth device is close
to the Module when performing this task.
For the purpose of this manual we have used the iPhone Bluetooth settings.

Once the blue led fl ashes you are ready to pair.
The Module remains in pairing mode for one minute.
If the Bluetooth device is not connected during this time, the Module will automatically turn off and you must repeat the process again.
To pair, go to the Bluetooth settings in your Bluetooth device (Smartphone, tablet, PC, etc.) and follow the respective search procedures. The Module will send its identifi cation code (KINGBT-XXXX) to your Bluetooth device. This is the moment to pair. This step will only be necessary the fi rst time for each Bluetooth device.
Now simple connect and play your music Your Bluetooth device will control all features such as choosing the song, play, pause, volume…
Once the connection is established the blue led will stop fl ashing and remain ON while the Bluetooth device is being used and within range of coverage (approx.10 meters).
