If the Master is powered down while in Concert Mode, the Slave units will play the
masters power down Prompt along with the master. This should be fixed in next
firmware release.
5.8. Charging Operation
Plugging in the charger will cause the hardware to enter charging operation and will be
indicated by the Blue LED indicator on the On/Off/Play/Pause button.
5.9. Charge Level Indication
The Play Pause button back light changes color depending upon the current level of the
battery charge state. Indications are:
1. Charging: Blue Solid.
2. Charge Complete: Blue Blinking. Not fully implemented.
3. Battery Low/Fault: Red Solid
4. Critical Level, Shut down Red Blinking followed by shut down.
5.9.1. Known Issues
Battery Low and Critical levels are not optimally set yet. Need to implement some
hysteresis because notice occasional bouncing between Battery OK and Battery Low
5.10. Turn Off
Press and hold the power button until the Power Down LED sequence starts.
5.10.1. Power OFF LED Sequence
The Power Off LED sequence starts with all button LEDs on for a half second. This is
followed by the Volume Up and Dwn buttons turning off. A half second later the
Concert mode and Next buttons turn off. Lastly, the Power/Play/Pause button turns off.
5.10.2. Known Issues
I’ ve noticed that occasionally the when the unit completes it power off sequence, it
appears to revert to on mode. The BT is not operational. Starting the Off sequence
again will cause the unit to turn Off.
