• If the wall plug transformer is damaged, do not touch it; there is danger to life from electric
shock! First, switch off the mains voltage to the mains socket to which the wall plug transformer
is connected (switch off at the corresponding circuit breaker or remove the safety fuse, then
switch off at the corresponding RCD protective switch, so that all poles of the mains socket are
disconnected). You can then unplug the wall plug transformer from the mains socket. Dispose
of the faulty wall plug transformer in an environmentally friendly way; do not use it any more.
Replace it with a wall plug transformer of the same design.
• Do not listen to excessively loud music for extended periods of time. It may damage your
hearing.
