Safety instructions

Never open electronic devices! This must only be done by authorised personnel and is all
the more important for current-carrying units. If devices are opened by customers in breach
of this instruction, the warranty becomes null and void.
Always disconnect the receiver from the mains by removing the plug when you wish to
change connections or move the device to a different place.
Keep the receiver away from central heating radiators and electric heaters. Never expose it
to direct sunlight.
Use the receiver in dry rooms only.
Use a damp cloth for cleaning the receiver. Do not use any cleansing agents or solvents.
