Group Cycling Computer
Owner’s Manual and Installation Guide 28
The computer will automatically determine your estimated maximal
heart rate (MHR) when you input your personal data during the setup.
The %MHR display indicates exercise intensity using the formula
220-age to represent maximum heart rate, and then current heart
rate as a percentage of the maximum.
8. What do I do if the computer is not picking up my heart rate?
Make sure the heart rate strap is fitted snugly at the bottom of
your ribcage and that the sensors are slightly moistened.
Follow the instructions on page 21 to pair your heart rate strap to
the computer.
Try changing the battery in your heart rate strap.
Check the distance between your heart rate strap and the
computer when pairing. You must be within 12 in. (30 cm) in
order to pair.
9. Which heart rate monitors are compatible with the computer?
2.4 GHz ANT+ heart rate monitors. To see if your brand heart
rate monitor is compatible, go to the product directory
https://www.thisisant.com/directory/star-trac-group-cycling-
computer/
and check to verify that your monitor is compatible.
5.3 KHz uncoded heart rate straps (e.g. Polar
®
)
10. Why am I picking up another users heart rate on my computer?
When bikes and riders are too close together while wearing analog
straps, it is possible to get crosstalk between the straps, where the
signal from rider shows up on the computer for another rider nearby.
Moving the bikes further apart should eliminate crosstalk. Using an
ANT+ heart rate trap will also prevent crosstalk.
11. Why is the computer not scanning between time, KCAL, and
distance?
The SCAN feature must be activated by pressing the Mode (
)
button three times. When the feature is activated, SCAN will appear
on the screen, and the computer will cycle through the data at three
second intervals.
12. Why is the computer timer not working?
You must press the Start (
) button to start the timer. The timer
may be in PAUSE mode if the timer has stopped. Press the Start
button to return to timing.
13. What is the life of the batteries, and what factors affect the life
of the batteries?
