When the interior of the cabinet is exposed, touching some parts can lead to an electric shock.
•
If you need to gain access to the interior electronics of the unit, always disconnect the unit from any and all power sources first.

•
If you need to replace any fuses, ensure that the replacements are of exactly the same type, value and voltage as the originals, as
spelled out in the technical specifications at the rear of this manual.
•
Do not use "repaired" fuses.
•
If you do not have fuses of the specified size, type and value, do not hot-wire the contacts in the holder by short-circuiting them.
•
Certain areas of the cabinet, cover, and rear panel can achieve extreme temperatures and are therefore marked with a "HOT" label
(Fig. B). Refrain from touching any heat sink or ventilation grille.
•
High volume levels are known to cause permanent - i.e. irreversible - hearing damage, especially when listened to without
sufficient breaks. The higher the levels, the more frequent and extended must be the breaks. Avoid standing too close to
loudspeakers that are being driven at high levels. If you must be exposed to high sound pressure levels over an extended period of
time, use hearing protection.
