Wearing The Chest Strap
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 re-
main 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 nal 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
difcult 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.
Note: The transmitter is automatically activated when it detects activity from the user’s heart. Additionally, it
automatically deactivates when it does not receive any activity. Although the transmitter is water resistant,
moisture can have the effect of creating false signals, so you should take precautions to completely dry the
transmitter after use to prolong battery life (estimated transmitter battery life is 2500 hours). The replacement
battery is Panasonic CR2032.
Caution! Do not use this treadmill for Heart Rate programs unless a steady, solid Actual Heart
Rate value is being displayed. High, wild, random numbers being displayed
indicate a problem.
Areas to look for interference which may cause erratic heart rate:
1. Microwave ovens, TV’s, small appliances, etc.
2. Fluorescent lights.
3. Some household security systems.
4. Perimeter fence for a pet.
5. Some people have problems with the transmitter picking up a signal from their skin. If you have problems try
wearing the transmitter upside down. Normally the transmitter will be oriented so the Spirit Fitness logo is
right side up.
6. The antenna that picks up your heart rate is very sensitive. If there is an outside noise source,
turning the whole machine 90 degrees may de-tune the interference.
7. Another Individual wearing a transmitter within 3’ of your machine’s console.
If you continue to experience problems contact your dealer.
