If replacing a power supply unit is required, please note the following:
■
■
■
■
The work should only be carried out by a suitably qualified electrician.
■
■
■
■
Make sure that the power supply system’s power switches are in the OFF posi-
tion and the unit is disconnected from the mains.
■
■
■
■
Observe the correct polarity when connecting the new PSU.
■
■
■
■
Note that a console must never have one voltage without the other, for example
+18V must never be fed into the console without -18V.
When switching the power supply back ON after replacement has taken place, make
sure that both LEDs on the front of the PSU-system come on. If only one LED comes
on, let go of the ON push-button immediately. Failure to do so may lead to fire hazard
and major damage to the console.
