Heart Rate Feature; Message Window Display - Spirit CT850 Owner's Manual

Next to the Dot Matrix window are three LED lights labeled: Track, Speed and Incline,
along with a display button. When the Track LED is lit the dot matrix displays the Track
profile, when the Speed LED is lit the Dot matrix displays the Speed profile and when the
Incline LED is lit the Dot Matrix displays the Incline profile. You may change the Dot Matrix
profile view by pressing the Display button. After scrolling through the three profiles the Dot
matrix will automatically scroll through the three displays showing each one for four seconds. The
LED associated with each profile will blink while that view is displayed. One more press of the
Display button will return you to the Track profile.
1/4 Mile T rack
The 1/4-mile track (0.4 km) will be displayed around the dot matrix window. The flashing dot
indicates your progress. In the center of the track there is a lap counter for reference.

Heart Rate Feature

The Pulse (Heart Rate) window will display your current heart rate in beats per minute during
the workout. You must use both left and right stainless steel sensors to pick up your pulse. Pulse
values are displayed anytime the computer is receiving a pulse grip signal. You may use the Pulse
grip feature at anytime. The CT850 will also pick up wireless heart rate transmitters, including
coded transmissions.
Heart Rate Bar Graph
Displays a graphical representation of your heart rate as a percentage of your estimated
maximum heart rate. When you enter your age during programming, the console will calculate
your estimated maximum heart rate then light up the graph to show the percent of estimated
maximum heart rate you are currently achieving.

Message Window Display

Displays messages that help guide you through the programming process. During a program the
message window displays your workout data.
T o T urn T readmill Off
The display will automatically turn off (go to sleep) after 30 minutes of inactivity. This function is
called sleep mode. In sleep mode, the treadmill will power down most everything except for a
minimum of circuitry for detecting key presses and the safety key so it will start up again if these
are activated. There is only a tiny amount of current used in sleep mode (about the same as your
TV when it is turned off) and it is perfectly fine to leave the main power switch on in sleep mode.
Of course you may also remove the safety key or turn off the main power switch to power
down the treadmill.
