3. The device must be free of any voltage before performing any alterations with upgrade sets,
switching the mains voltage, or performing any other modifications.
4. The minimum distance between voltage-carrying parts and metal parts that can be touched (such
as the metal housing) or between mains poles is 3 mm, and must be observed at all times.
5. The minimum distance between voltage-carrying parts and circuit parts that are not connected to
the mains (secondary) is 6 mm, and must be observed at all times.
6. Special components that are marked with the safety symbol in the circuit diagram (note) must only
be replaced with original parts.
7. Unauthorized changes to the circuitry are prohibited.
8. The protective measures issued by the relevant trade organizations and applicable at the place of
repair must be observed. This includes the properties and configuration of the workplace.
9. Observe the guidelines with respect to handling MOS components.

Safety precautions
Speaker system damage and protection of human beings
Power amps provide extremely high power output that might be dangerous for human beings as well
as for the connected speaker systems. High output voltages can damage or even destroy the
connected speaker systems, especially, when the amplifier is operated in bridged mode. Prior to
connecting any loudspeakers, make sure to check the speaker system's specifications for continuous
and peak power handling capacities. Even if amplification has been reduced through lowering the
input level controls on the amplifier's front panel, it is still possible to achieve full power output with a
sufficiently high input signal.
Danger!
Danger at the loudspeaker/power outputs
Power amplifiers are capable of producing dangerously high voltage output that is present at the
output connectors. To protect yourself from electric shock, do not touch any blank speaker cables
during operation of the power amp.
Danger!
The terminals marked with a lightning bolt are hazardous live and the external wiring connected to
these terminals requires installation by an instructed person or the use of readymade leads of cords.
Danger!
In case of using the amplifier with speakers including a primary tapped transformer, it is possible that
during operation shock hazard voltages may be present at the taps of the transformer. Therefore, the
taps have to be insulated sufficiently in accordance with applicable safety regulations.
