Wearing the chest belt
If you only wish to use the stopwatch function (and not record any fitness data), skip to ‘Start exercising’ section.
Signal unsuccessful?
The signal search will take approximately 30 seconds. If after 30 seconds the “NO HR BELT” is displayed, then your signal search has been unsuccessful. You can either:
1)Press +/ST/SP and proceed to use the watch as a stopwatch (without exercise recording function); or
2)Press MODE/- to force another signal search.
Analog or Digital?
The digital signal is less susceptible to signal interference and is suitable in crowded areas or where there are other monitors / equipment. You should only switch to the analog transmission signal if the situation in point 2 occurs (see ‘Encountering difficulties?’ below).
To switch from digital to analog or analog to digital system:
1) Press the chest belt button for more than 6 seconds.
2) Press and hold MODE/- on the watch to force a signal search.

Chest belt
The chest belt counts your heartbeat and transmits this data to the watch.
1.Wet the conductive pads on the underside of the chest belt with a few drops of water or conductive gel to ensure solid contact.
2.Holding the elastic strap, thread the plastic tab through the eyelet of the chest belt unit. Turn it
slightly and snap into place.
3. Place the heart rate chest belt slightly below your |
chest and wrap the strap around your chest. Pass |
Encountering difficulties?
In the event that you experience a weak signal or your signal is disrupted by interference in the environment, follow the instructions below to identify and resolve the situation.
1.The signal is weak - the watch may only show “0”:
•Shorten the distance between the heart rate chest belt and watch.
•
•Check the conductive pads are moist enough to ensure solid contact.
•Check the batteries. If they are low or exhausted, the transmission range may be shortened.
•Press and hold MODE/- to force a signal search.
2. The gym equipment does not seem to work with your chest belt and the digital icon is displayed:
• Most gym equipment is compatible with the analog system . Press and hold the chest belt button for more than 6 seconds to change from digital to analog. Then press and hold MODE/- to force a signal search.

NOTE You must enter the fitness level to calculate the calories burned.
TIP The watch generates calculations based on the inputted data to show the calorie / fat burned and the period exercised at the chosen intensity (target HR zone range) to help you track your progress over time. As you progress, update weight and fitness level to help the watch give you an

To ensure an accurate heart rate signal, adjust the strap until the belt sits snugly below your pectoral muscles.
TIPS
•The position of the chest belt affects its performance.
•In dry, cold climates, it may take several minutes for the chest belt to function steadily.
This is normal and should improve with several minutes of exercise.
NOTE To maintain the best performance of your chest belt, please handle it with care according to the following:
•Do not wrap the chest belt in a wet towel nor with other wet materials.
•Do not store the chest belt in a hot (about 122°F) and humid (about 90%) environment.
•Do not place or wash the chest belt under running water, instead clean it with a wet cloth.
•Do not place the conductive rubber face down on a metal table or surface.
•Properly dry the chest belt immediately after use.
Transmission signal
The heart rate chest belt and watch have a maximum transmission range of about 25 inches. They are equipped with the latest digital coding system to reduce signal interference from the environment, as well as analog technology.
Search for heart rate signal:
•Press MODE/- to select “EXE”, “HR BELT” will be displayed shortly after to indicate system is searching for chest belt signal.
NOTE Whenever the watch is searching for the chest belt signal (manual or automatic search), make sure that the chest belt is no further than 4 inches from the watch.
Your watch will advise you which system it is using and the signal status by displaying the following icons:

3.Interference from another person’s heart rate monitor - their heart rate readings appear on your watch, or the readings may fluctuate:
•Force another signal search by pressing the chest belt button then press and hold MODE/- on the watch. Do not press and hold the chest belt button, as it will change the transmission signal from digital to analog.
4.The signal is jammed - “NO HR BELT” appears on the display after several tries:
•There is too much interference in the environment for your heart rate monitor to function. Move to an area where the watch can register your heart rate reading.
WARNING Signal interference in the environment can be caused by electromagnetic disturbances. These may occur near high voltage power lines, traffic lights, overhead lines of electric railways, electric bus lines or trams, televisions, car motors, bike computers, some motor driven exercise equipment, cellular phones or when you walk through electric security gates. Under interference, the heart rate reading may become unstable and inaccurate.
Start exercising
If you wish to receive comprehensive calculations (such as your heart rate and the calorie / fat burned) for an exercise session, before you start, allow the watch a few seconds to search for chest belt first. For detailed information or if encountering difficulties, refer to “Transmission signal” section above.
Start taking measurements
If using only the stopwatch function:
1.Press MODE/- to select “EXE”, “HR BELT” will be displayed shortly after to indicate system is searching for chest belt signal.
2.Press +/ST/SP twice to skip heart rate signal search and start stopwatch.
MODE/- | +/ST/SP | +/ST/SP |

If using chest belt to receive and record fitness data:
1.Press MODE/- to select “EXE”, “HR BELT” will be displayed shortly after to indicate system is searching for chest belt signal. Watch will display system used (analog / digital), then the stopwatch screen.
