Do not let liquids get into the unit. This can cause electric shock or mal-
function. If this occurs, immediately disconnect the unit from the power sup-
ply and contact your dealer.
Do not spray insecticides onto or into the unit. They contain flammable
gases which can ignite if sprayed into the unit.

Do not attempt to repair this unit by yourself. If sound is interrupted, indi-
cators fail to light, smoke appears, or any other problem that is not covered
in these instructions occurs, disconnect the AC mains lead and contact
your dealer or an authorized service center. Electric shock or damage to
the unit can occur if the unit is repaired, disassembled or reconstructed by
