OPERATION INSTRUCTIONS
Exercising with specific goal:
• TIME Control: Set up a period of time to exercise.(Except in Program 2)
• DISTANCE Control: Set up a certain distance to exercise. (Except in Program 2)
• BODY FAT Control: Computer designs various programs for different people with different body fat rate.
• WATT Control: Keep different bodies burning in desirous WATT condition
Pulse Rate:
The whole set of heart rate detector includes 2 sensors each side. Each sensor has 2 pieces of metal parts. The correct way to get
detected is to gently hold both metal parts each hand. With the good signals picked up by the computer, the heart mark in the HEART
RATE/ BODY TYPE Display will flash.
(Options: Chest Belt for wireless pulse system is optional. If wireless pulse system is adapted, please refer to the leaflet of wireless
pulse system. It may not apply to all the models, only if the option is along with the computer.)
Manual Program:
Program 1 is a manual program. Press “ENTER” key to select TIME, DISTANCE, CAL, and AGE. Then, press ▲ or ▼ key to adjust the
values. The default level of loading is 6. After pressing “START/STOP” key to exercise, please also apply the heart rate detector
appropriately. Users may exercise at any desired level (by pressing ▲ or ▼ during the workout) with a period of time or a certain dis -
tance. With the input of age, the computer may suggest a target heart rate to exercise. The suggested heart rate is 80% (220-age). So,
if the heart rate detected equals to or greater than the TARGET H.R., the value of HEART RATE will keep flashing.
Please note that it is a warning for users to slow down or to lower the level of loading.
Preset Programs:
Program2 to Program7 is the preset programs. Press “ENTER” key to select TIME, DIST
ANCE, CAL, and AGE. Then, press ▲ or ▼
key to adjust the values. Users may exercise with different level of loading in different intervals as the profiles show.
After pressing
“START/STOP” key to exercise, please also apply the heart detector appropriately. Users may also exercise at any desired level
(by pressing ▲ or ▼ during the workout) with a period of a certain distance. With the input of age, the computer may suggest a target
heart rate to exercise. The suggested heart rate is 80% (220-age).
So, if the heart rate detected equals to or greater than the TARGET H.R., the value of HEART RATE will keep flashing. Please note that
it is a warning for users to slow down or to lower the level of loading.
5. Body Types:
There are 4 body types divided according to the FAT% calculated.
6. BMR: Basal Metabolic Rate
7. BMI: Body Mass Index
Type Man Woman
Type 1
(FAT=0.0%~13.0%) (FAT=0.0%~23.0%)
Type 2 (FAT=13.1%~25.8%) (FAT=23.1%~35.8%)
Type 3 (FAT=25.9%~30.0%) (FAT=35.9%~40.0%)
Type 4 (FAT=30.1%~50.0%) (FAT=40.1%~50.0%)

Computer Operation
Body Fat Program:
Program is a special program designed to calculate users' body fat ratio and to design a specific loading profile for users. With 4 8
different body types, the computer can generate 4 different profiles for each. Press “ENTER” key to select GENDER, HEIGHT WEIGHT
,
and
AGE. Then, press ▲ or ▼ key to adjust the values. After pressing “START/STOP” key to calculate body fat, please also apply the
heart rate detector appropriately. If the detector cannot pick up any signals, an error message "Err" will show up in the profile display. If
it happens, press “START/STOP” key to calculate again. Then, the calculation values of FAT%, BMR, BMI, BODY TYPE, and
a designed profile will show up shortly. Press “START/STOP” key to exercise. The profile shown in the display is specially designed for
your body type.
Heart Rate Control Program:
User Setting Programs:
Program 13 to Program 16 are the user setting programs. Users are free to edit the values in the order of TIME, DIST
ANCE, CAL,
AGE,
and the level of loading in 10 intervals. The values and profiles will be stored in the memory after setup. After pressing “START/STOP”
key to exercise, please also apply the heart rate detector appropriately. Users may also change the ongoing loading in each interval
by pressing ▲ or ▼ key, and they will not change the level of loading stored in the memory. With the input of age, the computer may
suggest a target heart rate to exercise.
The suggested heart rate is 80% (220-age). So, if the heart rate detected equals to or greater than the TARGET H.R., the value of
HEART RATE will keep flashing. Please note that it is a warning for users to speed down or to lower the level of loading.
Speed Independent Program:
Program independent program. Press “ENTER” key to select the values of TIME DIST17 is a speed
ANCE, W
ATT, and AGE. Then, press
▲ or ▼key to adjust the values. After pressing “START/STOP” key to exercise, please also apply the heart rate detector appropriately.
During the exercise, the level of loading is not adjustable. In this program, the computer will adjust the level of loading according to
the value of WATT setup. For example, the level of loading may increase while the speed is too slow. Also, the level of loading may
decrease while the speed is too last. As a result, the calculated value of WATT will close to the value of WATT setup by users. With the
input of age, the computer may suggest a target heart rate to exercise. The suggested heart rate is 80%(220-age). So, if the heart rate
detected equals to or greater than the TARGET H.R., the value of HEART RATE will keep flashing.
Please note that it is a warning for users to sleep down or to lower the level of loading.
Pulse Recovery:
It is a function to check the condition of pulse recovery that is scaled from 1.0 to 6.0 while 1.0 means the best and 6.0 means the worst
and the increment is 0.1. In order to get rated correctly, users must test it right after the workout finished by pressing
“TEST(RECOVERY)” key and then stop exercising. After the key is pressed, please also apply the heart rate detector appropriately,
the test will last for 1 minute and the result will show in the display. If the computer does not detect your current heart rate, pressing
“TEST(RECOVERY)” will not enter into the pulse recovery test. During the pulse recovery test, press “TEST(RECOVERY)” to exit the
test and return to the stop status.
Program 9 to Program12 are the heart rate control programs(H.R.C.).
In Program9, press “ENTER” key to select TIME DISTANCE,
CAL, and TARGET H.R. Users may setup a target heart rate to exercise in a period of time or a certain distance. In program 10 to
program 12, press “ENTER” key to select TIME, DISTANCE, CAL, and AGE. Then, press ▲ or ▼key to adjust the values. Users may
exercise in a period of time or a certain distance with 60% max heart rate in program 10, and 70% max heart rate in program 11, and
80% max heart rate in Program 12, After pressing “START/STOP” key to exercise, please also apply the heart rate detector
appropriately. 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. Also, the level of loading may decrease while
the heart rate detected is higher than TARGET H.R. As a result, the user's heart rate will be adjusted to close to the TARGET H.R. in
the range of TARGET H.R.-5 and TARGET H.R.+5.

Troubleshooting
If the computer is not picking up your hand pulse signal (or you are getting
inaccurate readings), please adjust the following:
1. Slightly moisten/dampen the palms with water so the sensors can detect a
pulse signal.
2. Do not grip the sensors too tightly. Only moderate pressure need be applied.
Gripping the sensors too tightly restricts and seizes detection of your pulse.
3. Remove any rings or jewelry to prevent interference.
4. Check to ensure all pulse sensor wires are properly connected and are
not damaged.
You may need to refer to installation/assembly directions for the pulse sensor
wires in this manual.
If the computer is not displaying the CALORIES/DISTANCE/TIME/(ETC.) functions
(or you are getting inaccurate readings), please adjust the following:
1. Check to ensure all computer sensor wires are properly connected and are
not damaged.
You may need to refer to installation/assembly directions for the sensor wires
in this manual.
If the computer display is blank & not displaying any data (or does not appear to
power on), please adjust the following:
1. Check to ensure all sensor wires are all properly connected and are
not damaged.
2. Check to ensure the AC Adapter* or Batteries* are properly plugged in or
fully charged.
