HEART RATE LIMITS / ALERT
TARGET ACTIVITY
| TARGET ACTIVITY | MHR % DESCRIPTION |
| WALK 65 - 78% | Health Maintenance: Low intensity training level. Good for those who want to strengthen their cardiovascular systems |
| JOG 65 - 85% | Aerobic Exercise: Increases strength and endurance. Works within body's oxygen intake capability, burns more calories, can be maintained for a long period of time |
| RUN 78 - 90% | Anaerobic: Generates speed and power. Works at or above body's oxygen intake capability, builds muscle, and cannot be maintained for a long period of time |
Before you begin any exercise program and to achieve maximum health benefits from your workout, it is important to know your:
• Maximum heart rate (MHR)
• Lower heart rate limit
• Upper heart rate limit
HEART RATE LIMITS / ALERT
To manually calculate your own heart rate limits:
| MHR | MHR = 220-age |
| LOWER LIMIT | MHR x lower target activity %.E.g. Target activity is WALK:Lower limit = MHR x 65% |
| UPPER LIMIT | MHR x upper target activity %.E.g. Target activity is WALK:Upper limit = MHR x 78% |
HEART RATE ALERT
You can set the heart rate alert in the heart rate mode to the following settings:
| ICON DESCRIPTION | |
| Heart rate sound alert is OFF | |
![]() | Heart rate sound alert is ON1 beep = you have gone below your lower zone limit2 beeps = you have gone above your upper zone limit |

or ▼ flash when you have surpassed your heart rate limit.
NOTES:
- Sound alert will only be activated if alert setting is ON and during exercise (when stopwatch is running).
- If the watch is kept idle without receiving a heart rate signal for 5 minutes, the heart rate mode will quit and return to clock mode.
USER DATA
To access the full benefits of this product, set up your user data before you exercise. This will automatically generate a fitness index, and enable the watch to calculate the level of calories burned when exercising. This information helps you track your progress over time.
To set the user data:
- Press MODE to navigate to the user data mode.
- Press and hold SET until the first setting fl ashes.
- Press + to change the setting. Hold to speed through the options.
- Press SET to confirm and move onto the next setting. The setting sequence is: Activity level (ATH / HOB / LIT), gender (M / F), year of birth, month of birth, day of birth, height unit (feet or meters), height, weight unit (lbs or kg) and weight. Once data has been completed the fitness index will display as FAIR, NORMAL or GOOD.

NOTE: You must enter your user data to enable the calorie count and fat burn features.
To view your fitness index:
Press MODE until you reach the user data display.
USER DATA
ACTIVITY LEVEL
The activity level is based on your own self-assessment of the amount of exercise you regularly perform.
| ACTIVITY LEVEL | DESCRIPTION |
| LITTLE | Low - You do not usually participate in programmed recreation sports or exercise. |
| HOBBY | Medium - You are engaged in modest physical activity (such as golfing, horseback riding, table tennis, calisthenics, bowling, weight lifting or gymnastics) 2-3 times a week, totaling 1 hour per week. |
| ATHLETE | High - You actively and regularly participate in heavy physical exercise (such as running, jogging, swimming, cycling, or skipping rope) or engage in vigorous aerobic exercise (such as tennis, basketball or handball). |
NOTE: You must enter the activity level to calculate the calories burned and fi tness index.
FITNESS INDEX
The watch will generate a fitness index based on your aerobic fitness. This index is dependent and limited by the body's ability to deliver oxygen to the working muscles in training. It is often measured by maximum oxygen uptake (VO2 Max), which is defined as the highest amount of oxygen that can be utilized when exercising at an increasingly demanding level. The lungs, heart, blood, circulatory system, and working muscles are all factors in determined VO2 Max. The unit of VO2 Max is ml/kg min.
USER DATA
See the tables below for a rough guide to what your fitness index means:

CHEST BELT
The chest belt counts your heartbeat and transmits this data to the watch.
- Wet the conductive pads on the underside of the chest belt with a few drops of water or conductive gel to ensure solid contact.
- Strap the chest belt across your chest making sure the belt sits snugly below your pectoral muscles.

natural_image

- For accurate heart rate readings, make sure the chest belt is placed above your heart.
- Avoid areas with dense chest hair.
- 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: If the watch is kept idle without receiving a heart rate signal for about 5 minutes, the heart rate mode will quit.
WEARING THE CHEST BELT
TRANSMISSION SIGNAL
The chest belt and watch have a maximum transmission range of about 25 inches (62.5 cm).
| ICON DESCRIPTION | |
| ♥ | Flashes when signal has been found |
| « » | Appears when heart rate alert is ON |
In the event that you experience a weak signal or your signal is disrupted by interference in the environment:
- Shorten the distance between the chest belt and watch.
• Re-adjust the position of the chest belt. - Check the conductive pads are moist enough to ensure solid contact.
- Check the batteries. If they are low the range may be less.
- When two or more people use the units nearby at the same time, ensure there is more than 45 inches (112.5 cm) between them.
NOTE: Signal interference in the environment can be due to 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.
STOPWATCH
To use the stopwatch:
-
Press MODE to navigate to stopwatch mode.
-
To start / stop / resume the stopwatch, press ST / SP.

If the watch heart rate function is activated and the user data has been entered, the calorie consumption will start counting when the stopwatch is running.

PERCENTAGE HEART RATE READING
The percentage heart rate reading is calculated from your current heart rate and MHR: × 100%
The higher the percentage, the harder the heart is working. For example, when you reach 80-90% you should consider slowing down to a more comfortable exercise level.
To turn the backlight on for 3 seconds:
Press ⚡️(Press again within the 3 seconds to extend the light for 3 more seconds.)
To turn the keypad lock ON or OFF:
Press and hold

NOTE: The backlight does not work when the low battery icon is shown and will return to normal once the batteries are replaced.
BATTERIES
The watch uses a CR2032 3V battery, which has already been installed. The battery warnings are:
| DESCRIPTION | |
| Continuous fl ashing The watch battery is low | |
| Intermittent fl ashing | The watch battery is too low to run the backlight |
* The batteries typically last one year.
To assure the water resistance take the watch to a local jewelry store for battery replacement. Improper replacement will void the warranty.
IMPORTANT:
Remember to set the profi les after every battery replacement or reset.
BATTERIES
The chest belt uses a CR2032 3V battery, which has already been installed. If the heart rate signals become unsteady or stop your chest belt battery may need replacing.
To replace the chest belt battery:
- Using a coin, twist the battery door counter-clockwise until it clicks out of place.
- Replace the old battery and close the battery door by twisting it clockwise until it is firmly in place.
