Before beginning any fitness program, you should see your
physician for a thorough physical examination.
• Read the Owner’s Manual and follow all instructions.
These instructions are written to ensure your safety
and to protect the equipment.
• Handle the Precor 903/904 electronic console with
care. Do not drop the equipment. It might damage the
device and you could void the Precor limited warranty.
• After extensive use, the batteries may wear out which
causes the information on the display to flicker
erratically or not appear at all. If you need to replace
the batteries, refer to Replacing the Batteries in the
maintenance section of this manual.
• Do not operate the treadmill for a 24-hour period after
installing the magnet and reed switch. A 24-hour
period is required so that the adhesive on the
mounting pads can bond properly.
The Precor 903/904 electronic console is designed to
enhance your workout. By following the above precautions
and using good common sense, you will have many safe
and enjoyable hours of healthy exercise with your Precor
products.

InstallingtheElectronicConsole
The handrail clamp can be used on either the 903 or 904
treadmill. However, the steps used to install the console
onto the clamp are slightly different depending on which
treadmill you have. Please refer to the steps that apply to
your treadmill.
903 Assembly Procedures
To install the 903 electronic console, take the following
steps:

3. Insert the long screws through the mounting holes on
the clamp. See Diagram 7. You may need to squeeze
the ends of the clamp together to install the screws.
Tighten the screws using a Phillips head screwdriver
until the clamp remains securely in place. A gap
should remain between the opposite sides of the
clamp. See Diagram 7.

bracket. It should “click” into place as you slide it
toward the rear of the treadmill.
9. Attach the C clips around the handrail as shown in
Diagram 5 on page 8. Position the slight protrusion on
the C clip around the reed switch wire and micro-
adjustment knob cable. Squeeze the C clips together
to close them and secure the wires in place.

Toinstallthemagnetandreedswitch,takethefollowing
steps:
CAUTION: To ensure the integrity of the reed switch,
lower the handrails before mounting the reed switch.
Allowing excess wire near the flywheel eliminates the
possibility that the reed switch will be pulled out of
position. If you are not sure how to lower the handrails,
refer to your Owner’s Manual.

4. To check the alignment between the magnet and reed
switch, move the flywheel slightly so that you can
place the base of the reed switch onto the foam
mounting pad. You should be able to see and read the
positive (+) signs. Position the reed switch between
the roller guard and deck so that the magnet passes

7. Secure the handrails into an upright position.
8. Check the wires to be sure no excessive amount of
wire hangs down where it could cause entrapment or
injury to someone. Realign the wire and move the C
clips along the handrail if necessary.
9. DO NOT OPERATE the treadmill for a 24-hour period.
The adhesive on the mounting pads requires this
amount of time to bond properly.
