C A U T I O N
Should you need to transport the amplifier, use the original packing as described
below.
First, switch off the amplifier. Pull the mains plug out of the outlet. Disconnect all cables from the rear
panel of the amplifier (remove the ground connection the last). Finally, pack the amplifier in its original
carton.
a) Storage environments: the amplifier can be kept packed in dry and ventilated unheated premises
without chemically active substances (acids, alkalis etc.) in the following climatic environment:
