Operation
Do not operate this unit before you have become familiar with its functions and with this
manual. Check all connections once again for correctness. Never operate the unit if it
appears damaged.
Make sure devices connected with the unit do not get overloaded. Playback must never
be distorted. Should distortions be audible, although the volume of the amplier was not
set too high, turn the unit off immediately and check the connections. If there is nothing
wrong with the connection, consult a technician.
