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.

Suggestions for Installation
General Suggestions
❍Group the audio components in a single location to minimize cabling. Always place the Transmitter directly on top
of amp when stacking with the other audio components.
❍If the audio components are stacked in a stereo cabinet, insure that there is adequate ventilation. The Cardio
Theater Amplifier and Digital Transmitter each require a minimum one inch (1") clearance on both sides for
ventilation.
Transmitter:
❍Place the Digital Transmitter in a well ventilated area with the front and back easily accessible.
❍Place the transmitter as high as possible to obtain the best possible transmission range.
❍Make sure the antenna on back of transmitter is in the vertical position.
Upper Monitors:
❍When mounting Upper Monitors to equipment, take care not to interfere with the normal operation of the
equipment.
❍Likewise, the power connections and the coiled cable connecting the Receiver box to the Upper Monitor should not
interfere with normal operation of the cardiovascular equipment.

❍If mounting the Upper Monitor to a control panel, avoid covering controls or indicators.
Receivers:
❍The Receivers should be mounted as high as possible on the cardiovascular equipment.
❍Mount the Receivers so that the antenna is on top in the vertical position.
❍Mount the Receivers securely so that vibration from normal equipment operation does not cause the receiver to
move.

System Connections
NOTE:

** The Cardio Theater Digital Transmitter works together with the Cardio Theater Main Amplifier. The Cardio Theater
Main Amplifier is shipped separately and is supplied with its own Installation Manual.
** Before continuing with this Installation of the Digital Transmitter and Receivers, please refer to the Cardio Theater
Main Amplifier Instruction Manual pages 9 - 12. Make all connections and adjustments to the Main Amplifier before
proceeding with this installation.

Receiver Configurations
There are two (2) configurations for attaching the receivers.
Contact the manufacturer of the cardiovascular equipment to determine if the unit is Cardio Theater ready, or
call the Cardio Theater Service Center (1-800-776-6695) for assistance.
Receiver with power
adapter and Upper
Monitor Box: For
cardiovascular equipment
that is not Cardio Theater
ready, power must be
supplied via a power
adapter connected to a
110 volt outlet. An Upper
Monitor Box is then
attached to the receiver.
Receiver powered by
machine with Upper
Monitor Box:For
cardiovascular equipment
that IS Cardio Theater
ready, power will be
supplied via a connector
on the cardiovascular
equipment. An Upper
Monitor Box is then
attached to the receiver.

Attaching Upper Monitors
The Upper Monitor can be installed on any piece of equipment.
For equipment with round handles or railing, Upper
Monitors are supplied with a build-in mounting block.
Align the Upper Monitor on the handle or rail as desired.
Use two of the supplied Plastic Wire Ties to attach the
Upper Monitor to the handle or rail.
Pull wire ties firmly to secure.
This method is the preferred method of attaching the Upper
Monitor to minimize interference with control panels and
displays.
For equipment with flat control panels but no hand
rails, SuperLock (a form of super strong Velcro) may
be used.
Determine the best mounting position.
Clean the mounting surface thoroughly.
Remove the protective cover from the adhesive strip.
Position the Upper Monitor and press firmly for the
adhesive to grip.
CAUTION: When attaching to a control panel, care should
be taken to avoid blocking access to controls or
illustrations.

Attaching Receivers
The Receivers can be installed on any piece of equipment.
IMPORTANT NOTE: Make sure the Receivers are mounted as high as possible in the vertical upright position
as much as physically possible, with the antenna on top.

For equipment with
round handles or railing,
the Receivers are
supplied with a build-in
mounting block.
Align the Receiver on
the handle or rail as shown.
Use two of the supplied
Plastic Wire Ties to attach
the Receiver to the handle
or rail.
Pull wire ties firmly to
secure.
For equipment that is
Cardio Theater Ready,
the receiver is mounted
either
(1) to the back of the
panel using the screw
holes, or
(2) attached to the
handle or rail.
For equipment with flat
vertical rails, align the
Receiver on the rail as
desired. Insert two Plastic
Wire Ties through the two
larger holes in each of the
L brackets. pull wire ties
firmly to secure.
For equipment that is
Cardio Theater Ready with

mounting holes provided
by the equipment
manufacturer on the back
of the panel, align the
Receiver to the equipment
and use either two (2) or
four (4) screws to attach
the Receiver.
