Set up
Connecting the powercord
1. Check if the voltage as indicated on the serial number plate matches the main power voltage
the system will be connected to. The serial number plate is located at the back of the
acoustic device.
2. Connect the supplied power cord to the main power connection. Integrated in the main power
connection is the main fuse (see drawing).
3. Connect the acoustic system to a grounded outlet. If it is not grounded some functions may
not work apropriate.
Switching on
First switch on the connected devices like the organ and e.g. a Hifi-equipment. Then switch on
the acoustic device by pushing the power switch. The power switch indicator light will light up.
