table. The product may fall, causing serious
injury to a child or adult, and serious
damage to the product. Use only with a cart,
stand, tripod, bracket or table recommended
by the manufacturer, or sold with the product.
Any mounting of the product should follow
the manufacturer’s instructions, and should
use a mounting accessory recommended by
the manufacturer.
9. A Product and Cart
Combination Should Be
Moved with Care. Quick
stops, excessive force and
uneven surfaces may cause
the product and cart combination to
overturn.
10. Ventilation. Slots and openings in the
cabinet are provided for ventilation and to
ensure reliable operation of the product and
to protect it from overheating, and these
openings must not be blocked or covered.
The openings should never be blocked by
placing the product on a bed, sofa, rug or
other similar surface. This product should not
be placed in a built-in installation, such as a
bookcase or rack, unless proper ventilation is
provided or the manufacturer’s instructions
have been adhered to.
11. Power Sources. This product should be
operated only from the type of power source
indicated on the marking label. If you are
not sure of the type of power supply to your
home, consult your product dealer or local
power company. For products intended to
operate from battery power, or other sources,
refer to the operating instructions.
12. Grounding or Polarization. This product
may be equipped with a polarized alternating-
current-line plug (a plug having one blade
wider than the other). This plug will fit into
the power outlet only one way. This is a
safety feature. If you are unable to insert the
plug fully into the outlet, try reversing the
plug. If the plug should still fail to fit,
contact your electrician to replace your
obsolete outlet. Do not defeat the safety
purpose of the polarized plug.
13. Power-Cord Protection. Power-supply
cords should be routed so that they are not
likely to be walked on or pinched by items
placed upon or against them, paying
particular attention to cords at plugs,
convenience receptacles, and the point
where they exit from the product.
14. Nonuse Periods. The power cord of the
product should be unplugged from the outlet
when left unused for long periods of time.
15. Outdoor Antenna Grounding. If an
outside antenna or cable system is connected
to the product, be sure the antenna or cable
system is grounded so as to provide some
protection against voltage surges and built-up
static charges. Article 810 of the National
Electrical Code, ANSI/NFPA 70, provides
information with regard to proper grounding
of the mast and supporting structure,
grounding of the lead-in wire to an antenna
discharge unit, size of grounding conductors,
location of antenna-discharge unit,
connection to grounding electrodes, and
requirements for the grounding electrode. See
Figure 1.
16. Lightning. For added protection for this
product during a lightning storm, or when
it is left unattended and unused for long
periods of time, unplug it from the wall outlet
and disconnect the antenna or cable system.
This will prevent damage to the product due
to lightning and power-line surges.
17. Power Lines. An outside antenna system
should not be located in the vicinity of
overhead power lines or other electric light or
power circuits, or where it can fall into such
power lines or circuits. When installing an
outside antenna system, extreme care should
be taken to keep from touching such power
lines or circuits, as contact with them might
be fatal.
18. Overloading. Do not overload wall
outlets, extension cords, or integral
convenience receptacles, as this can result in
a risk of fire or electric shock.
19. Object and Liquid Entry. Never push
objects of any kind into this product through
openings, as they may touch dangerous
voltage points or short-out parts that could
result in a fire or electric shock. Never spill
liquid of any kind on the product.
20. Servicing. Do not attempt to service this
product yourself, as opening or removing
covers may expose you to dangerous voltage
or other hazards. Refer all servicing to
qualified service personnel.
21. Damage Requiring Service. Unplug this
product from the wall outlet and refer
servicing to qualified service personnel
under the following conditions:
a. The power-supply cord or the plug has
been damaged; or
b. Objects have fallen onto, or liquid has
been spilled into, the product; or
c. The product has been exposed to rain or
water; or
d. The product does not operate normally
when following the operating instructions.
Adjust only those controls that are covered
by the operating instructions, as an improper
adjustment of other controls may result in
damage and will often require extensive work
by a qualified technician to restore the
product to its normal operation; or
e. The product has been dropped or
damaged in any way; or
f. The product exhibits a distinct
change in performance; this indicates a
need for service.
22. Replacement Parts. When replacement
parts are required, be sure the service
technician has used replacement parts
specified by the manufacturer or that have the
same characteristics as the original part.
Unauthorized substitutions may result in fire,
electric shock or other hazards.
23. Safety Check. Upon completion of any
service or repairs to this product, ask the
service technician to perform safety checks
to determine that the product is in proper
operating condition.
24. Wall or Ceiling Mounting. The product
should be mounted to a wall or ceiling only as

Test Tone
The test tone is used to calibrate the level settings of the
speakers. A static noise will be heard cycling, in order, from
the front left, center, right and both surround speakers.
Using the remote control, adjust the Center and Surround
levels until the volume of all the speakers is the same during
the test. The test tone is used to calibrate the performance
of the system. When listening to an actual recording, the
volume level of the surround channels is generally much
lower than that of the front channels. In fact, when listening
to a movie, virtually all of the dialogue and a substantial
number of effects are reproduced through the center channel.
Dol y Pro Logic, Hall and Concert Modes
1. Push the Test button on the remote control.
2. When the test tone is heard from the center speaker, push the +
or – Ctr/Rear Level button to match the volume of the center
channel to the front left and right channels.
3. When the test tone is heard from the surround speakers, push
the + or – Ctr/Rear Level button to match the volume of the
rear channels to the front.
6-Channel Input
1. Push the Test button on the remote control. The test tone
will cycle through all channels.
2. When the test tone is heard from the center speaker,
push the + or – Ctr/Rear Level button to match the volume
of the center channel to the front left and right channels.
3. When the test tone is heard from one of the surround
speakers, push the + or – Ctr/Rear Level button to match
the volume of that surround speaker to the front, left and
right channels.
4. Repeat step (3) when the test tone is heard from the other
surround speaker.
Please note that the 6-channel direct input mode has its own
level settings that are independent of the other modes.

If you hear no sound at all:
• Make sure the ESC230
main unit is plugged into a
live electrical outlet and
that the power switch is on.
• Check connections from
the ESC230 main unit to
the TV, VCR, DVD player
and the outboard surround
processor.
• If using with a television
or outboard surround
processor, make sure that
the TV or the surround
processor is on and a
signal is present.
• If using with a VCR,
make sure the VCR is
playing a tape.
• If using a DVD player,
make sure that the DVD
is playing.
• If using the 6-channel
digital direct inputs, make
sure that the 6-channel
mode is selected and its
indicator is illuminated on
the display. There will be
no output if the product is
in any other mode.
• If using the conventional
right and left inputs 1 or
2, make sure that Dolby
Pro Logic, Hall, Concert or
Stereo mode is selected
and its indicator is
illuminated in the display.
There will be no output if
the product is in the 6-
channel mode. Also make
sure that the appropriate
input (1 or 2) is selected as
illuminated in the display.
• Check all connections
between the ESC230
main unit and each of
the speakers.
If one or more of the speakers
does not play:
• Check all connections
between the ESC230
main unit and each of
the speakers.
• Adjust the balance
controls from left to right
and front to rear.
If you have very little bass
output:
• Make sure the subwoofer
is connected properly to
the ESC230 main unit.
• Experiment with place-
ment of the subwoofer.
Remember, place the
subwoofer in a corner
to get maximum bass
output from the system.
• Make sure Bass Boost
is on.
• Adjust Bass level.
If there is no sound coming
from the rear speakers or the
volume is very low:
• Check all connections
between ESC230 main unit
and each of the speakers.
• Adjust the front-rear
balance controls on the
ESC230 main unit.
• Make sure the TV show or
movie you are watching is
recorded in Dolby Surround.
If it is not, try the Concert
Hall or Stereo settings on
the ESC230 main unit.
When using the 6-channel
digital direct inputs, if there
is no sound coming from
some channels:
• Make sure that all 6
connectors are securely
connected on both the DVD
player/outboard processor
side and the ESC230 side.
• Make sure that the DVD
player/outboard processor’s
built-in decoder is correctly
configured to provide
output to all satellites
and the subwoofer.
(Depending on the product
you own, you may have to
do this using that specific
product’s on-screen
display.) Make sure that the
satellites are set to Small
and the subwoofer is set
to On by checking the
settings of the DVD player
or outboard surround
processor.
