Operational Instructions:
1. Manual Program (P1):
Press the “ENTER” key to select TIME, DISTANCE or CAL. Then, use ▲ or ▼ keys to adjust the values.
The default level of loading is 6. Press “START/STOP” to start your workout.
Users may exercise at any desired loading level (by pressing ▲ or ▼ during the workout) within a period of
time or a certain distance. With the input of age, the computer may suggest a target heart rate to exercise.
The suggested heart rate is 75%. So, if the heart rate detected is equal to or greater than the TARGET H.R.,
the value of HEART RATE will flash. Please note that this is an indication for the users to slow down or to
lower the level of loading.
2. Preset Programs (P1-P10):
Program P1 to Program P10 are the preset programs. Press the “ENTER” key to select TIME, DISTANCE,
CAL. Then, press ▲ or ▼ keys to adjust the values. Users may exercise with different level of loading in
different intervals as the profiles show. Press “START/STOP” to start your workout.
The loading level can be altered as desired during the workout. The heart rate recommendation function
mentioned above also applies in this mode.
3. Heart Rate Control Programs (P17-P20):
Press “ENTER” to select TIME DISTANCE, CAL, and TARGET H.R. Adjust these values using ▲ or ▼.
Users set a target heart rate to exercise in a period of time or distance.
P17: 55% max heart rate
P18: 75% max heart rate
P10: 95% max heart rate
The heart rate programs will require you to use the pulse sensors during the workout. In these programs, the
computer will adjust the level of loading according to the heart rate detected. For example, the level of
loading may increase while the heart rate detected is lower than TARGET H.R. The level of loading may
decrease while the heart rate detected is higher than TARGET H.R. The program will work to keep the users
