1. Read all the instructions before attempting to use the ACT-18X.
2. Follow all instructions contained in this manual.
3.
Keep these instructions in a safe place where they can be found and
referred to in the future.
4.
Use common sense in operating your ACT-18X and heed all warnings
included in your operating manual.
5. Do not use the ACT-18X near water. Do not use it in or near a washtub,
sink, pool, standing water, bathtub, or anyplace where the likelihood of
water mixing with electricity is present.
6. Clean only with a clean dry cloth.
7. Do not locate your ACT-18X in an area which has limited or very poor
ventilation. Obstructing the fan intake, outlet or the heat sink will likely
cause the product to overheat and shut down.
8. Do not install the ACT-18X near any heat sources such as radiators,
stoves, portable electric heaters or other devices that produce significant
amounts of heat. If you do, it could cause the product to overheat and
shut down.
9. Do not touch the amplifier heat sink with an ungloved or
unprotected hand while or shortly after the ACT-18X has been operating.
The heat sink may get hot during operation.
10. Do not attempt to defeat the safety purpose of the AC cord’s polarized
grounded plug. If the provided plug does not fit your outlet, hire an
electrician to replace the obsolete outlet.
11. Protect the AC mains power cord from being damaged.
12.
SERVICING - The user should not attempt to repair a damaged or
inoperable ACT-18X other than by replacing a blown AC mains fuse or a
damaged detachable power cord. DO NOT TOUCH A DAMAGED POWER
CORD IF IT IS PLUGGED INTO AC MAINS POWER!!!!!
13.
Turn off and unplug the ACT-18X when not in use except during a lighting
storm. A lightning strike on the AC line equipment is plugged into could
cause electrocution to those in contact with that equipment. This is why
your ACT-18X comes with a 3-prong power cord. The third prong (Earth
ground) is to prevent such harm. Should you believe an electrical storm
to be imminent, then it would be wise to unplug the ACT-18X BEFORE the
storm approaches.
14. To reduce the risk of fire or electric shock, do not expose the ACT-18X to
rain or moisture.
15. Servicing may be required when the ACT-18X has been damaged. If any
of the following conditions listed below has occurred, please turn off and
unplug the ACT-18X and seek the help of qualified service personnel. The
following conditions all require service:
1) The power-cord or plug is damaged.
2) Objects have fallen into, or liquid has been spilled into the amp.
3) The ACT
-18X has been exposed to significant moistur
e such as rain or
fog and or ther
e is pr
esent condensation inside the amplifier due to
weather conditions. (If ther
e is condensation on the outside of the
heatsink, it is safe to assume the condensation is present inside as well.)
4) The unit is not operating normally.
6) The unit has been dropped with significant force and is not
operating normally.
