5.7. Concert Mode
Concert mode is initiated by pressing the Vol+ and Vol- simultaneously for ~ 0.5 seconds.
Master Mode: To initiate Concert mode, first have the unit that is to be the master Powered
up and connected to a phone. Press and release the Concert mode button to initiate the
master operation.
Slave Mode: The slave unit(s) must be powered up and displaying Pairing mode (All LEDs
blinking). If the unit is connected to a phone, go to the phone and disconnect the unit so it
reverts to pairing operation. Once in this mode, initiate Concert mode as above. The unit
will initiate the broadcast stream in 5 to 10 seconds.
5.7.1. Concert Mode LED indication
Concert mode will be indicated by both the Vol- and Vol+ buttons indicated by initially
blinking on-off-on at a half second then remaining on. This is the same whether Master
or Slave concert mode operation is used. The master will also have its Play button
indicating the current Play/Pause state, while the Play button will be “Off” in the slave
mode.
NOTE: During Concert mode, there is no means for which the master to communicate
to the slave devices which Operational Mode (On Vehicle or Off) it is operating in, so
currently each slave will remain in which ever Operational Mode it was in upon
entering concert mode. Goingforwards, it was requested to have all units (Master and
Slave) to default into Off Vehicle Mode. We still need to determine upon Exiting
Concert mode if the slave units revert to their previous Operational Mode or not. We
will also need to know whether the mode button is to be disabled in Concert mode or is
the user able to change Modes while in Concert Mode operation.
5.7.2. Known Issues
Currently to exit concert mode the unit must be shut down and restarted. This should be
fixed in next firmware release.
There is no local volume control while in Concert mode Slave mode. This should be
fixed in next firmware release.
Slave unit gets no indication when Concert Mode stream is started or ended. This
should be fixed in next firmware release.
Save unit does not give proper indication of DSP Mode if toggled (always off). This
should be fixed in next firmware release.
