HEART RATE CONTROL PROGRAMS
Calculate your maximum Heart Rate before starting to
exercise. Do not exceed 85% of the maximum heart
rate.
•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%.
1. If you are 30 years of age, your maximum
heart rate is 220 – 30 = 190 BPM (Beats Per
Minute).
2. 190 x 0.65 = 123 BPM.
3. 190 X 0.85 = 161 BPM. Do not exceed 85%.
•For safety reasons it is advisable to exercise at
below 85% of the maximum heart rate.
After selecting the user the LEDs for the various
programs will start flashing on the right hand side of
the monitor. MANUAL, PROGRAM, USER, H.RC and

(200 cm) and press ENTER/MODE to confirm. Weight
will appear, select using the ▼▲ keys (between 44
lbs. (20 kg) to 330 lbs. (150 kg) and press
ENTER/MODE to confirm.
Select the target heart rate for the exercise. Use the
▲/▼keys to select the desired option (55%, 75%
90% [DO NOT use 90%, DO NOT exceed 85%] or
THR) and press the ENTER/MODE key. The first
three represent the percentage with respect to
maximum heart rate (220-age) and the fourth is used
to specify the target heart rate manually. In the first
three cases, the lower window on the display
(TARGET H.R.) will show you the calculated value for
your maximum heart rate level. If you choose THR
then you should use the ▲/▼keys to select the
desired heart rate and then press ENTER. Press
START / STOP to start the exercise. The exertion
level will adjust automatically in accordance with the
selected hart rate value. If the pulse rate is below the
target value then the exertion setting will increase by
one level every 30 seconds until it reaches the
maximum 16. If the pulse rate is above the target
value the monitor may give out warning beeps and
reduce the exertion settings by one level every 15
seconds until it reaches the minimum 1. If the pulse
rate still stays above the target value for more than 30
seconds the monitor may beep and stop in order to
protect the user.
To program time, distance, calories and/or pulse rate,
go through the following procedure: Once the heart

exertion level for the exercise is self adjusting based
on the speed and number of watts selected. Three
symbols will help you with your training sessions:
▲– Within the work margin, this indicates that the
speed is too high and you should slow down.
▼– Within the work margin, this indicates that the
speed is too low and you should speed up.
------- This indicates that the watts being produced are
outside the work limit (either too high or too low) so
you should speed up or slow down accordingly. The
monitor will beep several times to indicate this status.
If the situation continues for more than three minutes,
the monitor will give six beeps and then switch itself
off, resetting the watt value back to zero.
HAND-GRIP PULSE MEASUREMENT
INSTRUCTIONS - USE
PULSE Hand-grip
On this model the pulse rate is measured by placing
both hands on the sensors (R), located on the
handlebar, as shown in Figure 2.
When both hands are placed on the sensors the heart
symbol on the right-hand side of the screen, marked
PULSE, will begin to flash and after a few seconds a
heart rate reading will be displayed.
If both hands are not placed correctly as shown in
figure 3 then the pulse function will not work.
If a «P» appears on the screen or the heart symbol
does not flash, make sure that both hands are placed
correctly on the sensors.
TELEMETRIC PULSE RATE
The monitor is equipped to receive signals from a
telemetric pulse measurement system.
The system comprises of a receiver (D) and a
transmitter (chest band) Fig 4.
This telemetric pulse rate system takes
precedence over the Hand-grip pulse rate system
when both are used together.
See telemetric pulse rate instruction at the end of this
manual).
TEST MEASUREMENTS: FITNESS
This electronic device is equipped with a recovery test
function. This offers you the advantage of being able
to measure how long it takes your heart rate to
recover after having finished the exercise. Upon
finishing the exercise leave your hands on the pulse
sensors (R) and press the «Recovery» button, this will
start a one minute countdown. Only the Time and
Pulse rate function read-outs will remain displayed.
The electronic device will measure your pulse rate
during this minute. The heart rate recovery time will be
displayed on the Heart rate line.

C8 Bike (H872)

If, at any time during this minute, you decide to
abandon this test then press the «Recovery» button
and this will take you back to the main screen.
When the minute is up, the electronic device will work
out the difference and your fitness rating will be
displayed up on the screen: «F1, F2,..., F5, F6»;
where «F1» is the best (fitness «Excellent») and «F6»
the worst (fitness «Very Poor»).
Pressing the RECOVERY button will take you back to
the main screen, where the functions will be in the
same mode as when the test began.
The comparison between the worked heart rate and
the recovery heart rate provides a fast, simple method
of gauging how fit you are. Your fitness rating is a
guideline that shows you how fast your heart recovers
after physical exertion. If you exercise regularly then
you will see your fitness rating improve.
The test does not work unless you have both hands
placed on the sensors (R) (Hand-grips). In this case
the message «F6» will appear on the screen at the
end of the test.

INSTRUCTIONS FOR THE TELEMETRIC PULSE SENSOR
USE OF THE CHEST BAND
(Pulse sensor)
The chest band (optional extra) transmits the pulse rate by contact with the chest and sends signal to the display
clock.
PRECAUTION. Before beginning any exercise program, you should consult to your doctor and tell him about the
intensity of the exercise. If you use a pacemaker do not use the band until you have consulted with your doctor.
ASSEMBLY AND USE OF THE CHEST BAND
The key to flawless heart rate measure-ment is putting the transmitter on correctly as described below.
1. Attach the chest transmitter (E) to the elastic belt (F).
2. Adjust the strap (F) to fit tightly and comfortable.
3. Secure the strap (F) around your chest, below the breasts and lock the buckle.
4. Without detaching the elastic strip (F), pull the transmitter away from your body exposing the two grooved
areas that are located on the inside of the transmitter. Wet the grooved electrode areas with saliva, contact lens
solution or any other saline solution. Return to its original position against your skin with the Polar text in a central
up-right position.
5. After wetting the electrodes, do not slide the transmitter around on your body as this has the effect of drying the
electrodes.
It is recommend to wear the transmitter against bare skin to ensure successful operation. If a transmitter is worn
over a shirt, the shirt has to be well wetted under the electrode area to ensure proper conductivity.
Wear the band as high as possible just below the breast bone with the transmitter in the centre and the electrode
contacts flat against the skin. Doing this correctly assures a correct reading of the heart beat.

C8 Bike (H872)

HOW TO IMPROVE CONDUCTIVITY
The technology used for the chest transmitters is based on measuring ECG signals operation, it is important for
successful heart rate measurement that a proper electrical connection between the skin and the electrodes of
Polar Transmitter can be established and maintained during exercise. Sometimes, dry skin or hairy chest can
create a non-conductive layer between the electrodes and chest which prevents proper and reliable operation of
transmitter.
Conductivity can be easily improved through properly wetting properly the electrodes by water, saliva, contact
lens solution or other saline solution.
HOW TO GET A PROPER ECG SIGNAL FOR TRANSMITTER
It is possible, however, that despite the above mentioned recommendation, the transmitter does not work well due
to a slightly divergent ECG signal. ECG signal of some human beings can be so weak or the optimum location
may vary that transmitter has to be moved slightly to left or right in order to get sufficient voltage difference for the
proper operation of transmitter. Weak ECG signal can result from heart diseases, heart surgeries or natural
characteristic of heart and the location of the body potential vectors.
Important. Do not bend or stretch the electrode strips as this may permanently damage sensitive internal
electronic components.
Recommendation. If you have a sunken chest, the rubber electrodes may not make a good contact without
additional pressure and the result will be intermittent readings. Adding a second chest band on the transmitter can
solve this problem.
Please remember that this pulsometre, just as all devices that do not use cables, can it be affected by
electromagnetic interference. These can cause incorrect readings on your pulsometre.
Sources of interference or situations that can cause incorrect readings are:
- Your monitor picks up signals in a radius of approximately 29 inches (75 centimetres). If you are carrying out
exercises too near to another person that is wearing a pulsometre, your screen can pick up their signal. To avoid
maintain the appropriate distance.
- Television set, computers, cellular telephones, lines of high tension and electric motors can produce
Interference.
If you observe an erratic reading move away from the interference source. Your pulsometre will then return to
work correctly.
It is important to place the chest band correctly to obtain a correct measure.
CARE AND MAINTENANCE OF THE TRANSMITTER
-To maintain proper level of operation, the transmitter has to be cleaned regularly after use with a mild soap and
water solution. If you, however, want to disinfect your transmitter after use, a chlorine solution similar to that
approved for pool swimming may be used. Please avoid untested disinfecting compounds, they may cause
permanent damages to the transmitter. After disinfecting, transmitter should be cleaned by water or soap solution
to avoid allergic reactions on skin.
- After using, clean and dry your unit carefully. A weak signal can be due to dirt.
- Do not expose your band to excessive heat or cold.
- Do not leave your unit exposed to direct sunlight or in your car
- Keep your unit in a well ventilated place.
Note. Never use abrasives and other chemicals as they may cause permanent damages to the electrodes
decreasing conductivity or durability.
Storing of transmitter. It is highly recommended to store transmitter in cool and dry place to maximise the battery
life. Before storage all moisture should be wiped off.
FREQUENTLY ASKED QUESTIONS AND ANSWERS
Question 1: Heart rate readings take a long time to appear.
Answer 1:
If the heart rate readings start appearing after you start perspiring, this is an indication that the transmitter
electrodes weren’t initially wetted properly prior to commencing the exercise.
Question 2: If there is no heart rate reading, please check the following things:

Answer 2:
a) The transmitter should be placed on the rib cage just below the breasts with the word “Polar” facing out,
reading right side up.
b) With the transmitter in position and reasonably tight around the chest of the user, pull the transmitter away from
the body and wet the electrodes with water, saliva, contact solution or other saline solution.
c) If the readings still fail to appear, please have someone else try the transmitter on and see if that person can
get it to work.
d) The following medical conditions may create problems:
•Premature ventricular contractions, tachy-cardia bursts, and arrythmias can result in strange or no heart rate
readings.
•If the customer has an implanted medical device such as a pacemaker, you must consult your physician prior to
using the Polar Transmitter.
e) The ECG signal perceived by transmitter is too weak for successful measurement. Heart diseases, heart
surgeries or natural characteristics of a heart may result in weak ECG signals. In many cases, where a weak ECG
signal is the reason for problems, the reliable operation can be obtained by moving transmitter a little bit to the left
or right. Remember to rewet electrodes.
f) Electromagnetic interference. Polar transmission can be affected by high power transmission lines or other such
devices that generate powerful magnetic fields located in the area of equipment usage. If someone of your
associates has a Polar heart rate monitor, if possible, borrow it for a while to check that unit works properly in the
area of exercise equipment. If it does not and it works outside or another area of the house, the location is very
difficult for wireless heart rate measurement and the equipment should be moved to another location.
g) Receiver has broken down for some reason.
Question 3: Irregular heart rate reading
Answer 3:
a) The most common reason for irregular readings especially at the beginning of exercise session is that there is
no proper connection between skin and the electrodes of transmitter. To ensure a proper connection, electrodes
should be wetted prior to exercising.
b) Elastic strap is too loose allowing ransmitter to move during exercise.
c) Ensure that there is no anyone else wearing a transmitter in the reception area of your receiver. If there are
other transmissions close to you crosstalk may appear, unless you are using the coded Products Polar products.
d) Pacemaker and other implanted devices may change the electrical characteristics and operation of heart so
that transmitter detects several beats instead of one beat.
e) Some people have a reversed ECG signal compared to normal a ECG signal possibly causing a transmitter to
send two pulses for each heart beat. Please turn transmitter upside-down.
f) Interferences. Electrical equipment such as monitors, motors, LED displays, transformers switches, cellular
phones and etc. generate electromagnetic noise which may cause missing or extra pulses resulting in incorrect
heart rate reading
