CE Statement
Unpacking Your S4 & Placement Guidelines
Unpacking
Carefully remove your S4 from its shipping carton and locate the enclosed
accessories:
• AC and DC power cord
• A 12V trigger wire for auto turn on. It has a mono 3.5 mm mini plug at each end.
• Remote.
While you are unpacking your S4, inspect it thoroughly for possible shipping
damage and tell your KECES dealer immediately if you find any evidence of
shipping damage. This would be a good time to make a copy of your sales
receipt to store with the S4’s original packing.
Note:
Please save and store both the inner and outer cartons and, most especially, the
foam packing inserts to protect the S4 if you have to move it or ship it. You may
wish to flatten the cardboard cartons to save room in storage after cutting the
taped seams on the bottom flaps.
--------------------------------------------------------------------------------------------------------
Placement Guidelines
The S4 will be easier to use and will last longer if you follow these simple
guidelines:
• Place the S4 on a surface that will adequately support its weight.
• Use input and output cables that are long enough to leave some slack; that will
enable you to pull the S4 out of a cabinet to check or to change connections
without inadvertently disconnecting cables.
• The S4 should never be placed in a completely enclosed cabinet.
• Place your S4 where you can route input and output signal cables as far as
possible from any AC cords.
Ventilation Requirements
• Always position the S4 horizontally.
• The S4 should never be stacked directly above another power amplifier or
directly below another component.
• Do not install the S4 in an unventilated equipment cabinet or compartment.
Pockets of stagnant hot air can build up even in a cabinet with an open front and
back. A ventilation fan is recommended to prevent “hot spots” in confined
spaces.
AC Mains Voltage
Make sure the 115V/230V Voltage Selector switch on the S4 Power bottom plate
is set for the correct Ac line(mains) voltage before you plug in the power cord. It
can be seriously damaged if this switch is set for the wrong AC mains voltage.
In the 115V position the S4 can safely operate with AC Line voltages between
110-125V which is correct for North America, Mexico, and Taiwan. In some
countries, such as Brazil, AC voltages differ by region. Most other countries
require setting it to 230V. With the 230V setting the S4 can operate safely with AC
line voltages between 220-250V. If the AC Voltage Selector is changed the rear
panel fuse value must also be changed. The S4 operates on 50Hz or 60Hz AC.
Note:
An S4 that has been damaged by connection to the incorrect AC mains voltage
is not covered by the KECES warranty.
