■ Do not attempt to use your upright for any purpose other than for the purpose
it is intended.
■ The pulse sensors are not medical devices. Various factors, including the
user’s movement, may affect the accuracy of heart rate readings. The pulse
sensors are intended only as exercise aids in determining heart rate trends in
general.
■ Wear proper shoes. High heels, dress shoes, sandals or bare feet are not
suitable for use on your upright. Quality athletic shoes are recommended to
avoid leg fatigue.

STEP 1:
1. Locate the Console Mast (2) and slide on the Console Mast Cover (107). Make
sure the cover is facing the correct direction, as shown below, before sliding onto
mast. Install the wiring harness (80) into the bottom of the mast and out the top. Be
careful when installing the console mast to the mainframe so as not to pinch or cut
the wiring harness, damage to the console may occur.
2. Secure Front Stabilizer (4) and Rear Stabilizer (5) with 4pcs of 3/8" Cap Nuts (98),
4pcs of 3 /8"Curved Washers (96)and 4pcs of 3/8" × 2-3/4" Carriage Bolts (95)
by using 14&15mm Wrench (79).

Wearing The Chest Strap (Sold Separately)
1. Attach the transmitter to the elastic strap using the locking
parts.
2. Adjust the strap as tightly as possible as long as the strap
is not too tight to remain comfortable.
3. Position the transmitter with the logo centered in the
middle of your torso facing away from your chest (some
people must position the transmitter slightly left of center).
Attach the final end of the elastic strap by inserting the
round end and, using the locking parts, secure the
transmitter and strap around your chest.
4. Position the transmitter directly below the pectoral
muscles.
5. Sweat is the best conductor to measure very minute heart beat electrical signals.
However, plain water can also be used to pre-wet the electrodes (2 ribbed oval areas on the
reverse side of the belt and both sides of the transmitter). It’s also recommended that you
wear the transmitter strap a few minutes before your work out. Some users, because of
body chemistry, have a more difficult time in achieving a strong, steady signal at the
beginning. After “warming up”, this problem lessens. As noted, wearing clothing over the
transmitter/strap doesn’t affect performance.
6. Your workout must be within range - distance between transmitter/receiver – to achieve a
strong steady signal. The length of range may vary somewhat but generally stay close
enough to the console to maintain good, strong, reliable readings. Wearing the transmitter
directly on bare skin assures you of proper operation. If you wish, you may wear the
transmitter over a shirt. To do so, wet the areas of the shirt that the electrodes will rest upon.
