Important Safeguards
Please read all of these safeguards before operating the unit. Follow all warnings placed on the unit and adhere to
the operating and use instructions. Retain your manual for future reference.
1. Power sources - Connect the unit to a power source
only of the type described in the operating instructions or
as marked on the appliance.
2. Power cord protection - Route all power-
supply cords so that they are not walked on or
pinched by items placed upon or against
them.

3. Grounding - Take precautions so that the grounding
or polarization means of the unit are not defeated. 4. Ventilation - Position the unit so that its location does not interfere with ventilation. To maintain good
ventilation, do not put items on or over the unit. Do
not use the unit on a cushioned surface that may
block the ventilation openings.
5. Water and moisture - Do not locate the unit near
water. 6. Temperature - The unit may not function properly if used at extreme temperatures. The ideal
temperature is 41oF (5oC) to 87oF (30oC)
7. Heat - The unit should be located away from heat
sources such as radiators, heat registers, stoves, etc. 8. Electric shock - Care should be taken so that
objects do not fall and liquid is not spilled on the
enclosure. If a metal object, such as a hairpin or a
needle, comes in contact with the inside of this unit,
a dangerous electric shock may
result.
9. Enclosure removal - Never open the enclosure. If
the internal parts are accidentally touched, a serious
shock may occur.
10. Cleaning - Do not use solvents such as alcohol;
paint thinner, etc. to clean the unit. Use a clean dry
cloth.

11. Abnormal smell - If an abnormal smell is detected,
immediately turn the power OFF and disconnect the
power cord. Contact your dealer or service center.
12. Stands - Any component should be moved
with care. Quick or excessive force could cause the
stand to overturn.
13. Nonuse periods - The power cord should be
disconnected when left unused for a long period of time. 14. Damage requiring service - The unit should be serviced by a qualified technician when:
A. The power supply cord or the plug has been
damaged;
B. Objects have fallen, or liquid has been spilled into
the unit;
C. The unit has been exposed to rain;
D. The unit does not appear to operate normally or
exhibits a marked change in performance; or
E. The unit has been dropped, or the enclosure
damaged.
15. Servicing - The user should not attempt to service
the unit beyond that described in this manual. All other
servicing should be referred to a qualified technician.
Safety Precautions
WARNING: To prevent fire or electric shock, do not expose this
appliance to rain or moisture.
Caution: If you see this symbol,
be aware of its meaning: To
reduce the risk of electric shock,
do not remove the cover or back
of the unit. No user-serviceable
parts are inside. Refer servicing
to a qualified technician.

This symbol is intended to alert
the user to the presence of
uninsulated "dangerous voltage"
within the product's enclosure
that may be of sufficient
magnitude to constitute a risk of
electric shock to persons.
This symbol is intended to alert
the user to the presence of
important operating and
maintenance instructions in the
literature accompanying the unit.

Suggestions for Installation
General Suggestions
❍Provide for cable or an antenna for radio and television reception. The type of building and the location
could effect reception.
❍Use televisions with "Audio Out" or preferably "Line Out." If you are using televisions with "Audio Out"
the external speakers should be turned off and the volume set to the highest level.
❍Televisions should be arranged so that every user has a clear view of all televisions. Stagger the rows of
cardio equipment placing shorter pieces (e.g., recumbent bikes) in front and taller pieces (e.g., steppers)
toward the back.
❍Tuners or receivers may be used. If you are using a receiver, DO NOT use the speaker out connections as
this may damage the equipment. Instead use the "Record Out" or "Line Out."
❍Group the audio components in a single location to minimize cabling.
❍If the audio components are stacked in a stereo cabinet insure there is adequate ventilation. The Cardio
Theater Amplifier requires a minimum one inch (1") clearance on both sides for ventilation.
Main Amplilfier:

❍Place the Main Amplifier in a well ventilated area with the front and back easily accessible.
❍Number the audio components to match corresponding channel selections on the Upper Monitors.
❍Label cables as you connect them to the Main Amplifier. This will avoid any guess work in the future.
Upper Monitors:
❍When mounting Upper Monitors to equipment, take care not to interfere with the normal operation of the
equipment.
❍Likewise, the Coiled Cable connecting the Upper Monitor to the Floor Monitor should not interfere with
normal operation of the cardiovascular piece.
❍If mounting the Upper Monitor to a control panel, avoid covering controls or indicators.
Floor Monitors:
❍Floor Monitors should be secured to the floor, or in a sub floor. DO NOT attach the floor monitor to the
cardiovascular piece. This will cause problems when machines are moved (i.e., elevating treadmills), or for
cleaning.
❍Floor Monitors may be screwed down using the mounting holes or adhered to the floor using a strong
double-sided cloth tape.
Cabling and Connectors:
❍DO NOT SUBSTITUTE ANY TYPE OF CABLE OR CONNECTOR OTHER THAN THAT SPECIFIED
BY THE MANUFACTURER.
❍The Coax Cabling and the Floor Monitors can be installed under the floor, either in a sub floor or in a
conduit. In lieu of a sub floor or conduit, use an above-floor conduit system to protect the cabling, such as
a rubber raceway.
❍The most predominant method of covering the Coax Cable above floor is a rubber raceway molding
(Wiremold catalot number 1500). It is a narrow cable cover with beveled edges and a low profile that will
not interfere with traffic flow. It may be secured to the floor with double-sided cloth carpet tape, screws,
or nails. Wiremold catalog number 1500 may be purchased from Cardio Theater at (800) CARDIO-1, or
[phone].
❍There are four (4) output connectors on a 16-channel Amplifier and two (2) on an 8-channel Amplifier.
Use all four (or two) and divide the Upper Monitors evenly among them. For example: if you have 20
Upper Monitors on a 16-channel system, connect 5 Upper Monitors to each of the output connectors.

❍The maximum total length of the Coax Cables connected to any one output is 400 feet.
❍A maximum of 20 Upper Monitor sets can be connected on a single Coax line.
❍The system is designed to work with the monitor boxes connected in a daisy-chain or serial configuration.
❍DO NOT CREATE BRANCHES OFF A MAIN LINE! See drawing below:
