exercise. Do not use the heart rate features until
authorized by your physician.

• The target heart rate is determined using a simple
calculation:

(220 minus age) multiplied by 70%

Owner’s Manual: Heart Rate Features 11

• After you put on the chest strap, face the display console
for a minimum of 15 seconds. This allows the receiver in
the console to recognize the signal from the chest strap.

• If three dashes (— — —) appear on the display, the treadmill
cannot detect a heart rate. Make sure the chest strap is
positioned properly around your chest and against your skin.

• Always face forward on the treadmill and use the handrail
for balance.

Using SmartRate

The SmartRate feature helps you monitor and maintain your
heart rate in the target zone best suited to your specific
needs. When you wear a chest strap, a blinking LED appears
on the SmartRate display. The blinking LED indicates the
zone that your heart rate is in, either weight loss or
cardiovascular.

The SmartRate indicator lights do not appear when:

• You press QUICKSTART at the banner

• You bypass the AGE prompt

• You do not wear or improperly position the chest strap

Note: Review the information on the QUICKSTART card that
accompanies your literature packet. It explains how to adjust
the chest strap.

Owner’s Manual: Heart Rate Features 12

For the ideal weight loss range, the first, second, and third
SmartRate LEDs are lit and the fourth LED blinks. If you’re
working out in the cardiovascular zone, the fifth or sixth LED
should be blinking. Refer to Table 1.

Exercise to Your Target Heart Rate

The treadmill includes a program that lets you exercise
based on a specified heart rate. You set your target heart
rate at the beginning. As you exercise, the Heart Rate
Control program monitors your heart rate and automatically
maintains it within a few beats per minutes (bpm) of your
selected target. Your actual heart rate (pulse) appears in the
display when the HEART RATE LED is lit.

To use this program, select HRC. You must also wear the
chest strap so the program can monitor your heart rate
throughout the workout. For more information, refer to Heart

Rate Control (HRC) Program.

The center display shows the following information. This
information is shown in alphabetic order.

CALORIE S—displays the estimated cumulative number of
calories burned. The calorie calculation is derived from the
speed, incline, and your weight. An accurate weight entry
results in a more accurate calorie count. When using
QUICKSTART and a weight has not been specified, the
default weight is 150 pounds (68 kilograms).

DISTANCE—shows a linear distance in either miles or
kilometers. The distance is calculated based on your speed.

HEART RATE—displays your heart rate. If you are wearing
the chest strap, the display shows your heart rate when the
LED is lit.

The heart rate LED lights if the heart rate receiver is installed
in the display console, otherwise the feature is skipped. If
you wish to purchase the heart rate option, refer to Obtaining
Service.

INCLINE—displays the percentage of incline during your
workout. The INCLINE ▼ or ▲ keys affect the lift and let you
set an incline between 0% and 15%. The values displayed
can change in 0.5% increments.

PROFILE—appears on the display and corresponds to the
program you selected. As you continue your workout, a
blinking column indicates your position in the program.
Changes in incline affect the column height as shown in
Diagram 6.

If the profile is only one row high, then markers ( )
appear occasionally and provide a sense of movement
through the program.

SPEED—displays the running belt speed in miles per hour
(mph) or kilometers per hour (kph). The running belt speed
ranges from 0.5 to 11 mph (1 to 18 kph) and can be
changed in 0.1 increments using the SPEED ▼▲ keys.

Owner’s Manual: Display Console 15

SCAN—lights when the scanning feature is active. The
display consecutively scans through the highlighted features
(PROFILE, TIME, DISTANCE, etc.). Indicator lights appear
next to the feature being displayed. You can change which
features appear by pressing the SELECT key. Refer to
Changing the Display Features Using the SELECT Key.

TIME—displays workout time in minutes and seconds;
however, when you exceed 60 minutes during a single
workout, the time display converts to hours and minutes. For
programs with a workout time limit, the TIME display shows
the amount of time remaining. For programs without a
workout time limit, the TIME display indicates the amount of
time you have been exercising.
