Heart Rate Measuring - Sensors Configurations
6.0

• In exercise or sports, your heart naturally speeds up in pumping blood to the
body in accordance with your increased energy level. This watch can calculate
that increase expressed as the number of beats per minute (bpm) to determine a
safe target heart rate for each individual.
PRECAUTIONS/TIPS
1. A heart rate sensor is located on the back of the watch. The back sensor must
make firm contact with the user’s skin during Finger-Touch measurement.
2. There are 2 contacts located on the back of the chest strap. The sensors must
make firm contact with user’s skin during Chest-Strap measurement.
3. DO NOT take heart rate measurement when diving or under water.
4. Clean the back cover of the watch and the back of the chest strap occasionally by
applying a few drops of water and wipe it dry with a paper towel. It can help
removing any residual grease.
5. DO NOT use hand cream; it will insulate the signal between the skin and the
sensors.
6. Clean fingers with soap and water for better signal transmission.
7. Clean skin around chest area with soap and water for better signal transmission.
8. DO NOT use the fingertips where the skin is dry and thick.
9. For those with extremely dry skin, moisten the skin with tap water or apply a
conductive gel may help.
10. Hold the watch firmly when taking Finger-Touch measurement in motion.
11. Adjust the Chest Strap with the supplied elastic band until it is hold on your chest
firmly to avoid loosen it when doing exercise.
12. During the measurement, avoid any awkward motion. Awkward motion creates
undesired muscle noise; hence an incorrect heart rate reading may result.
Heart Rate Measuring - Precautions and Tips
6.1

What is Heart Rate Zone?
Some particular training/exercise
objectives like ‘aerobics’, ‘fat burnt’ or
‘health’ that require trainees/exercisers
maintaining their heart rates (exercise
paces) within one particular heart rate
zone during the exercise.
WARNING: Consult a doctor or trainer
prior to set the heart rate alert zone for a
serious cardio-fitness training.
How to Select a Zone (for Heart Rate Zone Alert)?
In general, users may get the cardio-fitness training advices from those prestigious
organizations’ website, for example:
• http://www.heart.org/HEARTORG/Conditions/CongenitalHeartDefects/
CareTreatmentforCongenitalHeartDefects/Congenital-Heart-
Defects-and-PhysicalActivity_UCM_307738_Article.jsp
by American Heart Association.
• http://en.wikipedia.org/wiki/Heart_rate#Training_zones
by Wikipedia.
• This Watch includes three pre-defined heart rate zones (“AROBIC”, “FAT-B” and
“HEALTH”) and one user-defined heart rate zone (”USR”) for user selection.
• The upper and lower limit of these Zones is shown on the adjacent diagram.
Check chapter 6.6 for the details on how to select a Zone.

Note:
• When taking a heart rate measurement, various visual indicators will be displayed
according to the different zones. A single beep will sound to alert whether heart
rate is out of the present zone.
• Please refer chapter 6.6 for details on turn ON/OFF Zone Alert.

Heart Rate Measuring - Heart Rate Zone Alert
6.2.1

• During exercise or sports, your heart
naturally speeds up pumping blood to the
body in accordance with your increased
energy level.
• The Heart Rate Chronograph Mode and
Instant Heart Rate Mode shows the
current heart rate in terms of:
• Heart Rate (e.g 78) : The number of
heart beats per minute (bpm), and
• Percentage of Estimated Maximum
Heart (e.g 40%): The percentage of
the acquired heart rate with respect to
one's estimated maximum heart rate.
Percentage of Estimated Maximum Heart
Rate
• It is a useful figure for analysing the
cardio-fitness of a person.
• It can be used to define a heart rate zone
for cardio-fitness training.
• Consult your doctor for more information
on the implications of Percentage of
Estimated Maximum Heart Rate.
NOTE: The user MUST input his/her age and
gender into the watch. Check chapter 5.1 for
the details on age and gender settings.
Estimated Maximum Heart Rate (EMHR):
• EMHR = 220 - user age.
• Example: What is Tom's EMHR at his
age of 27?
• EMHR = 220 - 27 = 193.
NOTE: This Watch can calculate the EMHR
for user the age up to 99.
Percentage of Estimated Maximum Heart
Rate (%EMHR):
• %EMHR =
Acquired heart rate ÷ EMHR X 100%
• Example: What is Tom's %EMHR if he
has acquired a heart rate of 78.
• %EMHR = 78 ÷ 193 X 100% = 40%

different exercise information,
please refer chapter 6.5. / For
more details on Zone Setting,
please refer chapter 6.6.
Measuring Heart Rate by Finger-Touch
Following the steps below, you can measure your heart rate
by touching the sensor on the watch.
(1) Make sure the sensor on the back of the watch sits firmly
on your skin.
(2) Place your index finger on the stainless steel top cover
[HR].
(3) Keep holding for about 5 seconds. When the heart rate is
detected, the heart rate will be displayed on the screen.

How to Wear the Chest Strap
• Refer to the below steps to wear the
chest strap on one’s chest:
1) Extend the elastic band for allowing a
loose fitting the chest strap on your
chest.
2) Connect one connector with the chest
strap. Ensure that the connector is
completely lodged into the chest strap.
3) Fit the chest strap on your chest with
one hand.
4) Connect the opposite connector to the
chest strap with the another hand.
5) Fasten the elastic band until it is fitted
on your chest comfortably.
6) Adjust the chest strap until the two
contacts are firmly contacted with
your skin.
IMPORTANT: DO NOT wearing the chest
strap over your cloth, otherwise the chest
strap CANNOT get the heart rate signal.
NOTE: In dry seasons, wetting the contacts
with some water can make the signal
transmission better.
Heart Rate Measuring - Wearing the chest strap
6.4

Measuring Heart Rate by Chest Strap
• Beside Finger-Touch, users can also measure
their heart rate by using chest strap.
• To measure heart rate by chest strap, first,
wear the chest strap following the instruction
of chapter 6.4.
• Go to “Heart Rate Chronograph Mode” and
the watch will start measuring automatically.
• When heart rate signal detected, the heart
rate measured will be exhibited on the
screen. Percentage of Estimated Maximum
Heart Rate (%EMHR) will also be exhibited
on the left.
• The Maximum heart rate and the Average
heart rate during measurement will also be
shown on the 1st row.
NOTE:
• The Maximum and Average Heart Rate
calculation will include the result from
finger-touch measurement.
• Hold the [R] button in Heart Rate
Chronograph Mode will reset all the
calculations and records stored in the watch,
including Chronograph, Zone Timer, Fat and
