6.1 Heart Rate Measuring - Precautions and Tips
● In exercise or sports, your heart naturally speeds up pumping blood in your 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 an individual.
PRECAUTIONS/TIPS
1. There are 2 contacts located on the back of the chest strap. The sensors must make firm
contact with the user’s skin during heart rate measurement.
2. DO NOT take heart rate measurement when diving or under water.
3. Clean 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 remove any residual grease.
4. DO NOT use hand cream; it will insulate the signal between the skin and the sensors.
5. Clean skin around chest area with soap and water for a better signal transmission.
6. For those with extremely dry skin, moistening the skin with tap water or applying a
conductive gel may help.
7. Adjust the Chest Strap with the supplied elastic band until it holds on your chest firmly to
avoid loosening when doing exercise.
8. For best results, maintain a natural gait while moving. Jerkey or unnatural movement will
create muscle noise, and will interfere with the sensor.

6.2 Heart Rate Measuring - Heart Rate Zone
What is Heart Rate Zone
● Some particular training/exercise objectives like
'aerobics', 'fat burn' or 'cardo' require the trainee/exer-
ciser to maintain his/her heart rate (exercise pace)
within one particular heart rate zone during the
exercise.
WARNING: Consult a doctor or trainer prior to
setting the heart rate alert zone for a serious
Cardio-fitness training.
How to Select a Zone (for Heart Rate Zone Alert)
● This Watch includes three pre-defined heart rate
zones (“HEALTH”, “FAT-B” and “AEROBIC”) and one
user-defined heart rate zone (“USR”) for selection.
● The upper and lower limits of these Zones are shown
in the adjacent diagram. Check chapter 6.5 for the
details on how to select a Zone.

6.2.1 Heart Rate Measuring - Heart Rate Zone Alert
Note:
● When a user taking a heart rate measurement, various visual indications will be
displayed according to his/her heart rate and the pre-set limits. Besides, a single
beep will sound to alert the user when his or her heart rate is out of the preset zone.
● Please refer to chapter 6.5 for details on how to turn ON/OFF the Zone Alert.

6.2.2 Heart Rate Measuring - About EMHR and %EMHR
● During exercise or sports, your heart naturally
speeds up pumping blood in your body in
accordance with your increased energy level.
● The Heart Rate Chronograph Mode and Instant
Heart Rate Mode show the current heart rate in term
of :
● Heart Rate (e.g 78) : The number of heart beats
per minute (bpm), and
● Percentage of Estimated Maximum Heart Rate
(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 before using this function as the pre-set
values do not fit the user’s personal information. The
result/reading may not be relevant. Check chapter 5.1
for more details on age and gender settings.
Estimated Maximum Heart Rate
(EMHR):
● EMHR = 220 - user age.
● Example: What is Tom's EMHR at the
age of 27?
● His EMHR = 220-27 = 193.
NOTE: This Watch can calculate the
user’s EMHR with 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%

6.3 Heart Rate Measuring - Wearing the chest strap
Wear the Heart Rate Sensor:
1Moisten the electrode areas
of the strap.
2Attach the connector to the
strap.
3Adjust the strap length to fit
tightly but comfortably.
4Tie the strap around your
chest just below the chest
muscles, and attach the
hook to the other end of the
strap.
5Check that the moist
electrode areas are firmly
against your skin and that
the logo of the connector is
in a central and upright
position.
NOTE:
Detach the connector
from the strap and rinse
the strap under running
water after every use.
Sweat and moisture may
keep the electrodes wet
and the transmitter
activated. This will reduce
the transmitter battery life.

6.3.1 Heart Rate Measuring - Chest-Strap Measurement
Measuring Heart Rate by the Chest Strap
● First, wear the chest strap following the
instruction in chapter 6.3.
● Go to the “Heart Rate Chronograph Mode” and
the watch will start measuring automatically.
● When the heart rate signal is detected, the heart
rate acquired will be exhibited on the screen. The
Percentage of Estimated Maximum Heart Rate
(%EMHR) will also be exhibited on the right.
● The Maximum heart rate and Average heart rate
during measurement will also be shown in the 1st
row.
NOTE:
● Holding the [R] button in the Heart Rate
Chronograph Mode will reset all the calculations
and records stored in the watch, including
Chronograph, Zone Timers, Fat Burnt and
Calorie consumption.

6.4 Heart Rate Measuring - Heart Rate Chronograph Mode
Heart Rate Chronograph Mode and the
Sub-Functional Displays
● In the Heart Rate Chronograph Mode, there
are 8 different displays for showing the
exercise information. They are:
● Maximum / Average Heart Rate Display,
● Chronograph Display,
● Below Zone Timer Display,
● In Zone Timer Display,
● Above Zone Timer Display,
● Calorie Consumption Display,
● Fat Burnt Display and,
● Current Time Display.
● Press [R] to scroll through different
Sub-Functional Displays from the top row of

● In 'Zero' Display, press the [S/S] button once
to start the counting. When it is counting, hold
the [S/S] button to stop the counting, and the
accumulative elapsed time will appear.

Record.
To Reset the Chronograph
● When the chronograph is stopped, hold the
[R] button to reset the chronograph (ready for
a new counting).
NOTE
● While taking Lap Time, the average heart rate
for the Lap is also recorded.
● When the Chronograph is reset, the records
will also be reset.
