PULSE MEASUREMENT

The pulse measurement function uses a photosensor to detect the

movement of blood in your fingertip, which it then converts to a pulse

value. A biofeedback feature also lets you set a target pulse and monitor

your actual pulse in relation to your target.

Entering and Exiting the Pulse Measurement Mode

1. Pressing P in any mode enters the Pulse Measurement Mode,

indicated by

xx flashing on the display.

[Pulse Measurement] [Biofeedback]

Photosensor

Press B.

Target pulse

• The flashing indicates that the watch is waiting for you to place your finger

on the photosensor (standby). To stop the flashing, press P again. Each

press of P turns standby on (xx flashing) and off (xx not flashing).

• Press B to toggle between the pulse measurement screen and the

biofeedback screen.

2. Press C to return to the Timekeeping Mode.

Measuring Your Pulse

1. Make sure the pulse measurement screen

is in standby (xx flashing).

• If xx is not flashing, press P.

2. Lightly place your finger onto the

photosensor to start pulse measurement.

• Measurement continues for two minutes

or until you remove your finger from the

photosensor.

Wave indicator

Pulse value

Pulse graph

• Within about 7 to 15 seconds, a value showing the initial measurement

result appears on the display, along with a bar on the pulse graph and

a wave indicator that are synchronized with your pulse.

Note

• The pulse value on the display is updated every 2 to 3 seconds.

• Take care you do not change your finger pressure or move your finger

too much while it is on the photosensor.

• Either of the following indicates that the watch was unable to obtain a

good pulse reading.

xx: Unstable measured value

E: No pulse detected

• If you have problems getting a value to appear, press P to stop the

measurement procedure, and see “Tips on Placing Your Finger on the

Photosensor”.

Biofeedback

The biofeedback feature lets you compare your measured pulse with a

target pulse rate you preset. You can use this feedback to check the effect

of relaxation techniques designed to reduce your resting heart rate.

Joggers and endurance athletes can use this information to maintain their

optimum heart rate during training and to monitor post-workout recovery.

Caution!

Always stop running and stand in a safe place whenever

performing a pulse measurement. Measuring your pulse while

running creates the risk of personal injury to you and others.

To set your target pulse

1. In the Pulse Measurement Mode, hold

down A until the target pulse value flashes

on the display.

2. Press B to increase the target pulse value

or L to decrease it.

• You can set the target pulse value within the range of 30 to 200.

3. Press A to return to the biofeedback screen.

To perform a biofeedback operation

1. Make sure the biofeedback screen is in

standby (xx flashing).

• If xx is not flashing, press P.

2. Lightly place your finger onto the

photosensor to start pulse measurement.

• Measurement continues for two minutes

or until you remove your finger from the

photosensor.

• The target pulse value flashes whenever

the current pulse value reading is within

±5 beats of the target.

• See the “Note” of “Measuring Your Pulse”

for important pulse measurement

precautions.

Pulse Graph

The meaning of the data that appears in the pulse graph depends on

whether you are performing a pulse measurement screen operation or

biofeedback screen operation.

Pulse Measurement Screen

• The detection level indicates the relative quality of the pulse detection.

Level 0 (no dots) is the worst, while Level 5 is the best.

• A level of 4 or 5 indicates that the pulse reading is fairly reliable.

• On the pulse measurement screen, the graph shows readings that are

relative to the first reading. The first reading is automatically defined as

the central point. Because of this, the value range of each dot on the

graph is adjusted with each new measurement, based on the first

reading.

• The graph scale of the pulse measurement screen graph automatically

shifts up or down whenever a measured value is outside the current

graph scale.

STOPWATCH

The Stopwatch functions let you record elapsed time, lap times, and split

times. The range of the stopwatch is 99 hours, 59 minutes, 59 seconds.

You can also store lap and split times in memory.

• Stopwatch functions are available in the Stopwatch Mode, which you

can enter using C.

• For the first 10 hours, the screen shows hours, minutes, seconds, and

1/100 second. After 10 hours, the screen format changes to show

hours, minutes, and seconds.

[Hours, Minutes, Seconds, 1/100 second] [Hours, Minutes, Seconds]

Lap time

Split time

• The lap time appears in the upper part of the display. You can use this

function to time how long it takes to complete a specific portion (such

as a single lap) of a race.

• The split time appears in the lower part of the display. You can use this

function to time how long it takes to get from the start to a specific

point in a race.

Measuring Elapsed Time

1. Press B to start the stopwatch.

2. Press B to stop the stopwatch.

• You can resume the measurement operation by pressing B again.

3. Press L to clear the stopwatch to all zeros.

Recording Lap and Split Times

1. Press B to start the stopwatch.

2. Press L to display the timing up to that point. Stopwatch timing

continues internally.

• When you do, times are remaining on the display for about 10

seconds, and then the display changes back automatically to the

stopwatch display.

3. You can repeat step 2 as many times as you want.

4. Press B to stop the time measurement.

5. Press L to clear the stopwatch to all zeros.
