Wisdom Audio Series SA-3 - Manual (Page 15)

If you plan to be away for an extended period, or have any other reason to
turn the SA-3 completely off, you may either unplug the SA-3 or you may
use the
AC mains switch .
Danger! Potentially dangerous voltages and current capabilities exist within
your SA-3. Do not attempt to open any portion of the SA-3’s cabinet.
There are no user-serviceable parts inside your SA-3. All service of
this product must be referred to a qualified Wisdom Audio dealer or
distributor.
We recommend that care be taken to ensure that all AC plugs for the equipment
in the system be wired so as to ensure proper AC polarity. Doing so will mini-
mize noise in the system.
In the U.S., a simply AC mains tester (found at any hardware store) can test to
ensure that your electrical outlets are wired properly. Elsewhere in the world
(for example, in European Union countries), the AC mains plugs themselves are
not always polarized. Your dealer can test for the proper orientation of the plug
in the outlet. In such a case, it is good practice to mark both plug and outlet to
ensure that all products remain in the proper orientation should it become nec-
essary to temporarily disconnect the system (as for example, during an electrical
storm).
