Important Safety Precautions and Explanation of Symbols
The exclamation point within an equilateral triangle is intended to alert the user to the presence of
important installation, operation, and service instructions in this manual.
The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user
to the presence of uninsulated dangerous voltages within the enclosure that may be of sufficient
magnitude to constitute a risk of electrical shock to the user.
Please read this Installation and Operation Manual thoroughly before attempting to install, configure,
or operate the Sherbourn 4Z-75. After successful installation and configuration of the 4Z-75, be sure to
retain this manual in a safe place for future reference.
Safety is a key component to a long lasting and trouble free installation. Please read and follow
all instructions and heed all warnings on the 4Z-75 and in this manual. The vast majority of the
subsequent safety precautions are common sense. If you are not comfortable with the installation
of audio/video entertainment equipment, you should seek the services of a qualified installation
professional or call us for help.
WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT USE THE
4Z-75 NEAR WATER OR IN WET LOCATIONS, DO NOT EXPOSE IT TO RAIN OR MOISTURE,
DO NOT EXPOSE IT TO DRIPPING OR SPLASHING FROM OTHER SOURCES, AND ENSURE
THAT NO OBJECTS FILLED WITH LIQUIDS (SUCH AS VASES) ARE PLACED ON IT. DOING SO
MAY RESULT IN DAMAGE TO THE 4Z-75 AND THE RISK OF ELECTRIC SHOCK, WHICH MAY
RESULT IN BODILY INJURY OR DEATH.
WARNING: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE THE COVER
FROM THE 4Z-75. THERE ARE NO USER-SERVICEABLE PARTS INSIDE THE 4Z-75. REFER ALL
SERVICE TO QUALIFIED SERVICE PERSONNEL.
Do not install the 4Z-75 near or above any heat sources such as radiators, heating vents, or other
apparatus that produces heat. Do not block any ventilation openings or heat sinks. Avoid installing the
4Z-75 directly above other heat-producing equipment unless sufficient ventilation or forced-air cooling
is provided.
Do not install the 4Z-75 in locations without proper ventilation. The 4Z-75 should not be operated
on a bed, sofa, rug, or similar surface that may block vents. The 4Z-75 should not be installed in an
enclosed location such as a bookcase, cabinet, or closed equipment rack unless sufficient forced-air
ventilation is provided.
Always install your 4Z-75 according to the manufacturer’s instructions and only use attachments or
accessories specified by the manufacturer.
Do not install the 4Z-75 on any stand, shelf, or other piece of furniture that is unable to support its
weight. If a cart is used to move the 4Z-75, use caution to avoid injury from tip-over.
Connect the 4Z-75 only to power sources of the correct voltage (as shown in this manual and on the
4Z-75). Ensure that the Input Voltage selector switch on the rear of the 4Z-75 is set to the appropriate
voltage.
Protect power supply cables from being pinched, walked on, or otherwise damaged. Be especially
careful where the power cable enters the power outlet and the 4Z-75 unit.
Only connect the 4Z-75 to an electrical outlet or extension cord of appropriate type and rating.
DO NOT defeat the safety purpose of a grounding or polarized plug by removing ground pins or using
unsafe adapters. A polarized plug has two blades - one wider than the other. A grounding plug has a
third ground prong in addition to the two main conductors. The wide blade or third groundling prong is
provided for your safety. If the provided plug does not fit your outlet, consult an electrician to replace
your obsolete outlet. If you replace the 4Z-75 power cord, only use one of similar type and equal or
greater current rating.
