HEART RATE MONITORING
HEART RATE MONITOR
The AlterG display is designed to receive a user’s heart rate in
conjunction with the use of a Polar® (Chest Strap) Heart Rate
Monitor.
3
Polar chest straps can be purchased at most popular
sporting goods stores or online. In order for the screen to correctly
display a user’s heart rate, the receiver within the display must obtain a
stable heart rate signal from the Polar transmitter. The Polar Heart
Rate System consists of two main elements: 1) the sensor/transmitter
and the receiver within the AlterG display.
HOW TO WEAR THE CHEST STRAP TRANSMITTER
The Sensor/Transmitter is worn just below the chest and at the top of
the abdomen, directly on bare skin (not over clothing). The transmitter
should be centered below the pectoral muscles. Once the strap is
secured, pull it away from the chest by stretching the band, and
moisten the conductive electrode strips with plain water. The
transmitter operates automatically while you are wearing it; it does not
operate while it is disconnected from your body. However, as moisture
may activate the transmitter and salt buildup from sweat can be a
problem, rinse the transmitter with water and wipe it dry after use. The
chest band is washable. After you have detached the transmitter, wash
the band in warm water using mild soap and rinse thoroughly in clean
water.
THE RECEIVER
You must be within two and a half feet of the receiver in order for the
signal to be received. Please take note that your transmitter may
fluctuate erratically if you are too close to other Polar equipment.
Maintain at least a three-foot distance between other Polar units.
NOTE: Erratic heart rate reception may occur if the Polar Monitor is
too close in proximity to strong sources of electromagnetic radiation,
such as television sets, Personal Computers, electric motors and some
other types of fitness equipment. Only one transmitter should be used
inside the range of any one receiver as the receiver may pick up
several signals simultaneously, causing an inaccurate readout.
