W A R N I N G notes call attention to a procedure which, if not correctly performed,
could result in personal injury, fire hazard or electric shock.

C A U T I O N notes call attention to a procedure which, if not correctly performed,
could result in equipment damage, not only in the amplifier.

N O T E notes call attention to a procedure which, if not correctly performed, could
result in inconvenience.

W A R N I N G HIGH VOLTAGE!

The amplifier works with high voltages up to 3000V, which are LETHAL!
Also, for your safety, pull the amplifier power plug out of the mains wall
outlet and WAIT AT LEAST 30 minutes EACH TIME BEFORE you remove the
cover of the amplifier. Do not touch any part inside while the amplifier is
open because some residual voltages may still be present.

W A R N I N G HIGH VOLTAGE!

NEVER  ALLOW  ANYONE,  ESPECIALLY  CHILDREN,  to  push  anything  into
holes  in  the  case  -  this  will  cause  electric  shock.  NEVER  TOUCH  AN
ANTENNA during transmission - this may result in an electric shock or
burn.  NEVER  EXPOSE  the  amplifier  to  rain,  snow  or  any  liquids.  AVOID
placing  the  amplifier  in  excessively  dusty  environments  or  in  direct
sunlight. DO NOT OBSTRUCT AIR INTAKE (rear panel) and EXHAUST (top
cover) areas of the amplifier. Keep a minimum distance of 10cm (4 inches)
to the intake and 50cm (20 inches) to the exhaust openings.

W A R N I N G

Do not undertake on your own repairs or changes in hardware or software
of the amplifier. Otherwise you may endanger your or other's health and
life or damage the amplifier and the equipment connected with it, not
covered by warranty. The manufacturer is not liable for another's actions
and responsibility shall be assumed by the doer.

C A U T I O N

To avoid damage (not covered under warranty) read the Installation -
Section 2 of this operating manual carefully. If you have any doubts about
the installation, operation or safeties of the amplifier please consult your
dealer.
