ABOUT THE FITNESS / BODY MASS INDEX

FITNESS INDEX

Your 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 determining VO2 Max. The unit of

VO2 Max is ml/kg min.

The higher the index, the ﬁtter you are. See the tables below

for a rough guide to what your ﬁtness index means:

belt is splash proof, and should not be worn for underwater

activities, as the heart rate transmission cannot occur under

water. Refer to the table for proper guidelines.

observe the following guidelines:

• Do not press the keys under water or with wet ﬁngers.

• Rinse with water and mild soap after use.

• Do not use in hot water.

BATTERIES

Both the watch and heart rate chest belt use 1 x CR2032 3V

battery. Both are already installed. See the table below for

battery warnings.

LOW BATTERY ICON DESCRIPTION

The battery is too low to

run the backlight

The watch battery is low;

the backlight cannot be

used

The chest belt battery is

nearly too low to send a

signal to the watch

The batteries typically last one year. We highly recommend

that you contact the retailer or our customer service

department if you need to replace them.

To replace the watch battery:

1. Remove the watchstrap.

2. Undo the four screws and remove the back plate.

3. Using a thin blunt instrument, hook the release catch

and lift the clip.

4. Remove the old battery and slide the new battery into

the battery compartment with the + side upwards.

5. Replace the battery clip, back plate and screws. Then

re-attach the watchstrap.

To replace the chest belt battery:

1. Using a coin, twist the compartment lid counter-

clockwise until it clicks out of place.

2. Remove the old battery and insert the new battery with

the +side upwards.

3. Replace the battery compartment lid by twisting it

clockwise until it is ﬁrmly in place.

IMPORTANT

• Non-rechargeable and rechargeable batteries must be

disposed of properly. For this purpose, special containers

are provided for non-rechargeable and rechargeable

battery disposal at communal collection centers.

• Batteries are extremely dangerous when swallowed!

Therefore, keep batteries and small articles away

from children. If a battery has been swallowed seek

immediate medical advice.

• The batteries supplied must not be recharged,

reactivated by any other means, dismantled, put into ﬁre

or short-circuited.

ABOUT THE SMART TRAINING PROGRAM

The SMART TRAINING PROGRAM enables you to

complete exercise cycles effectively. It will guide you through

from a 5-minute warm-up (default setting) to the end of your

exercise program. In addition to monitoring your heart rate

and altering you whenever you fall out of the range for the

selected training zone, the Program allows you to check the

calories consumed and the % fat burned.

USING THE SMART TRAINING PROGRAM

The SMART TRAINING PROGRAM monitors your exercise

performance once you have entered your user proﬁle and

exercise proﬁle.

NOTE You cannot use the SMART TRAINING PROGRAM

if you are running the stopwatch.

To enter the SMART TRAINING PROGRAM:

1. Press MODE to enter TRAIN Mode.

2. To start or stop the warm up, exercise or recovery

countdown timer, press ST / SP / +. Once you stop any

countdown timer, you can press ST / SP / + again to

resume it. At the end of each countdown period you will

hear a beep.

• 3 short beeps = Warm-up time completed

• 1 long beep = Exercise time or distance completed

• 6 short beeps = Recovery time completed

3. To bypass a timer and move onto the next one, press

and hold ST / SP / +.

4. To reset the timer, press ST / SP / + to stop, then press

and hold SET.

The order of the Timer Mode is:

• Warm-up time

- The warm-up will not display if it has been set to “0”

in the exercise proﬁle.

• Exercise time or distance

- The exercise time or distance is set in the exercise

proﬁle.

• Rest time

- The rest (recovery) time is automatically set to 3

minutes and cannot be changed. When the timer

reaches “0”, the recovery heart rate will ﬂash.

NOTE You can enable or disable the recovery timer by

selecting On / Off setting in Exercise proﬁle (please refer to

Set Exercise Proﬁle – step 5).

completed, press MEM / - to enter memory mode. The

odometer will be displayed (to reset, press and hold SET),

press MEM / - to view the following records:

• Total time and maximum

heart rate

• Recovery heart rate and

average heart rate

NOTE You cannot use the SMART TRAINING PROGRAM

and the Stopwatch function at the same time.

RECOVERY HEART RATE

Your recovery heart rate is a good indication of cardiovascular

ﬁtness. The faster your heart rate recovers after the exercise,

the better shape you are in. The watch uses a time-based

recovery method, which checks your recovery heart rate 3

minutes after exercise.

Compare your recovery heart rate between exercise

sessions to track the effect your exercise is having.

STOPWATCH

The stopwatch function is particularly beneﬁcial to use when

you are unsure how long your activity will take, or when you

want to measure the time it takes to complete a task and

your performance over that time. You can also take lap and

split time readings when using the stopwatch function.

To get the most out of your stopwatch functions complete

your user and exercise proﬁle. If you have not completed the

user proﬁle you will be unable to use the calorie and % fat

burned function.
