Using a chest belt

Attach the transmitter to the elastic strap using the lock button.

Adjust the strap as tightly as possible as long as the strap is not too tight to remain
comfortable.

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.

Position the transmitter directly below the pectoral muscles.

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.

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 needs to be of the type CR2032.

ERRATIC OPERATION

Caution! Do not use this exercise equipment for Heart Rate Control 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 exercise equipments, 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 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 the service center.
