WEARING THE HEART RATE TRANSMITTER
Theheartratetransmitterstrapconsistsoftwoconductiveelectrodes
attached to a small radio transmitter housed in the center of the strap.
Theelectrodessensetheelectricalpotentialcreatedeachtimeyourheart
contracts and the radio transmitter sends a signal to the watch each time
the electrodes sense the heart beat.
Forthebestperformance,alayerofsweatshouldbebuiltupbetweenyourskin
andtheelectrodesofthetransmitter.Thismakesiteasierfortheelectrodes
to “see” the electrical signal.
Oncooldaysoratthebeginningofyourworkout,itmaybenecessary
to moisten the electrodes on the back of the transmitter using saliva
or one of the commercially available conductive creams.
DONOTusetapwatertomoistentheelectrodesastapwaterwillact
as an insulator rather than a conductor and may actually reduce
the performance of the system.
Thetransmittershouldbewornaroundtheribcage,justbelowthepectoralmuscles.
Theelasticstrapofthesystemshouldbeadjustedsothatitissnugenoughsoit
doesnotmoveduringuse,butnotsotightastorestrictbreathing.
Whilethewearingofthetransmitterstrapmayfeelabitstrangeinitially,
most people become used to it within a few days and cease
to even notice they are wearing it.
