Harmonik On-Batt LED indicator for Harmonik systems

The ON-BATT is an accessory that contains a  blue LED * to indicate that the pickup is ON and also a red LED that indicates that the battery should be replaced avoiding disturbances during the show and unnecessary battery changes.

* The blue ON LED can be disabled so only the red LED will operate to indicate battery replacement.

The ON-BATT can be installed in any of the Harmonik microphone systems.
