The maximum number of heartbeats that a person should not exceed is referred to as the maximum heart rate
and this value drops with age. A simple formula to calculate this is to subtract your age, in years, from the
number 220. The maximum heart rate should be kept between 65% and 85% for correct exercise, it is not
advisable to go above 85%.
Whenever your pulse rate exceeds 85% of the maximum heart rate value a flashing heart symbol will appear
and a 2 second beep will sound until your pulse rate drops below 85% of your maximum heart rate.
For safety reasons it is advisable to exercise at below 85% of the maximum heart rate.
P-12 CONSTANT HEART RATE PROGRAM (H R C).-
It is advisable to do a brief warm-up session before using this program. This will prevent possible injuries.
This program allows you to select a heart rate (between 65% and 85% of the maximum heart rate) and the
machine will automatically adjust exertion levels to ensure that the user maintains the selected heart rate
value. Use of heart rate measurement using the telemetric chest band is obligatory and you must not exceed
85% of your maximum heart rate value.
With the monitor switched on, the top LED array (A), Fig.2, will display the profile and the letter "M" for manual.
Use the LEVEL▲ and LEVEL▼ keys to display the various pre-programmed profiles. Once the HRC program
has been selected, press the ENTER key.
Press the ENTER key to modify the target heart rate and the LED window will display "ENTER PULSE
SETTING <40-220>" Press the number keys and the LED window will show "PULSE = xxx" and the
specified value will flash. Press the number keys to modify and enter a three digit number (values: 40 ~ 220
）. If the number is beyond these limits it will display a larger or smaller number. Enter a value within the
said limits and press ENTER to confirm.
Press ENTER to modify the time and the LED window will show "ENTER THE EXERCISE TIME
<MINUTES>" The dot matrix display will prompt "? 10" and flash the number you have specified. Press the
number keys to modify and enter a two digit number (values: 10 ~ 60）. If the number is beyond these limits
it will display the default time setting. Enter a value within the said limits and press ENTER to confirm. You
can now start the program.
After specifying the last setting, all of the values are stored together. The exertion level is 1 and moves to the
next line every minute. If the speed (RPM) is too slow, the dot matrix display will show "RPM↑" and switch to
pause mode alter 15 seconds.
Begin the exercise at a pedalling rate of between 70 to 80 R.P.M., place the telemetric chest band on your
chest. Should you go above or drop below this R.P.M then the top LED array (A), Fig2, will display the
"R.P.M ?" prompt.
This program uses a preset exertion level during the first three minutes in order to prevent any type of injury.
After the third minute, the computer will automatically adjust the exertion setting to keep the pulse rate at the
previously programmed value.
AUTOMATIC EXERTION SETTING
At the beginning of the exercise the machine sets the exertion level to minimum, i.e. 50W, until the first pulse
reading is taken.
Once the pulse rate is established the program calculates your heart rate every X seconds (this period can
be modified between 20 to 60 seconds within the SPR program).
The exertion setting based on pulse rate is explained in the following steps.
1.- TARGET HEART RATE greater than ACTUAL HEART RATE:
When the difference between the TARGET HEART RATE and the ACTUAL HEART RATE is equal to or
greater than 15 r.p.m., the AUTOMATIC EXERTION CONTROL will start increasing in steps of 20 Watts.
When the difference is less than 15 r.p.m the setting will change in steps of 10 Watts until both heart rates
match.
2.- ACTUAL HEART RATE greater than TARGET HEART RATE:
When the difference between the ACTUAL HEART RATE and the TARGET HEART RATE is equal to or
greater than 15 r.p.m., the AUTOMATIC EXERTION CONTROL will start decreasing in steps of 20 Watts.
When the difference is less than 15 r.p.m the setting will change in steps of 10 Watts until both heart rates
