Synchronizing the Watch with the Sensor Bar

Before you start exercising, make sure that the watch is receiving
the anti-interference code transmitted from the sensor bar, and
synchronize the watch with the sensor bar. See “Anti-interference
Code” for more information.

If you don’t synchronize the watch with your sensor bar, your
watch may start picking up the signal transmitted from another
sensor bar.

The sensor bar starts transmitting automatically as soon as you
put on the chest strap and the sensor pads start picking up your
heart beat.

While you are wearing the chest strap, press the 

C

 button while the

watch is in the Timekeeping Mode, Stopwatch Mode, or Timer Mode to
start synchronization.
After synchronization is complete, the watch will receive the signal from
the sensor bar and display your heart rate and exercise intensity.

The heart symbol will flash on the display while your heart rate is
being monitored.

Pressing the 

C

 button while the watch is monitoring your heart rate

will perform synchronization again.

Synchronization will be cancelled automatically if the watch is not able
to receive any signal from the sensor bar for about 60 seconds.

Important!

Never use this product if you are wearing a cardiac pacemaker or any
other type of medical device.

Do not use this product in the vicinity of anyone who is wearing a
cardiac pacemaker or any other type of medical device.

Do not wear this product while riding on an aircraft. Doing so creates
the risk of interference with the aircraft’s equipment.

Do not use this product if the strap causes skin irritation or any other
abnormality.

Anti-interference Code

The anti-interference code is a special unique code the sensor bar sends
to the watch to identify its signals, which ensures that the watch is able
to know what signal is coming from the sensor bar. If there are people
around you who are also using this type of watch, anti-interference
codes ensure that the watches don’t accidentally pick up another signal
by mistake.
In some rare cases, two watches that are near each other may end up
using the same anti-interference code. When this happens, you could
simply move away from the person whose watch is using the same code
to avoid picking up its signal by mistake. If this is impossible for some
reason, perform the following steps to change the anti-interference code
of your watch.

To eliminate signal interference

1. Take off the chest strap, and leave it off for about 90 seconds. Then,

put it back on again.

If the chest strap cannot detect a pulse for more than 90 seconds,
it will change to a new anti-interference code automatically.

2. In the Timekeeping Mode, Stopwatch Mode, or Timer Mode, press

the watch’s 

C

 button to start signal reception.

The watch will receive the new anti-interference code from the
sensor bar and synchronize with it.

If there is someone nearby using the same type of watch the first
time your watch receives a signal from the sensor bar, your watch
may synchronize with the wrong anti-interference code. Be sure to
move away from any other people who are also using this type of
watch before starting signal reception.

If your watch synchronizes with the wrong anti-interference code,
move away from the other person and press the 

C

 button while in

the Timekeeping Mode, Stopwatch Mode, or Timer Mode. Perform
the synchronization procedure again so your watch synchronizes
with your chest strap.

If you are about to run a race or in some other event with a large
number of people, be sure no one around you is using the same
type of watch at the start. If someone is, move away from them to
avoid synchronizing with the wrong anti-interference code. It is best
to perform the first receive from the sensor bar before starting the
race.

Heart Rate Monitor Troubleshooting

If this happens:

No heart rate appears on
the display, or displayed
values are excessive or
vary widely.

Heart rate measurement
suddenly stops
automatically.

Interference in the signal
from the chest strap.

The watch does not
calculate energy
consumed.

The energy consumed
value is strange.

Check this:

Is the strap attached to your chest correctly?

Your heart rate cannot be detected
correctly if the strap is not attached to your
chest correctly.

See “Monitoring Your Heart Rate During
Exercise”.

Are the sensor bar’s sensor pads (diamond
pattern areas) wet?

Your heart rate cannot be detected if your
skin is dry.

Warm up until you start sweating or
moisten the sensor pads with water.

Are the sensor bar’s sensor pads dirty?

Dirty sensor pads interfere with stable
heart rate pickup.

Clean the sensor pads as required. To clean
the sensor pads, wipe them with a soft, dry
cloth, or with a cloth that has been moistened
in weak solution of water and a mild neutral
detergent. Wring out all excess liquid from
the cloth before wiping. Never use thinner,
benzene, alcohol, or any other volatile agent
to clean the sensor pads.

Is the sensor bar’s battery dead?

If so, contact your dealer or CASIO
distributor to have the battery replaced.

Is there some source of electromagnetic
waves (high-tension power lines, TV, cell
phone, etc.) nearby?

Electromagnetic waves can make normal
heart rate detection and communication
impossible.

Possible sources of electromagnetic
waves are: signal equipment, overhead
railway cables, electric bus cables,
streetcars, automobiles, motorcycles,
computers, motorized fitness equipment,
medical devices, electronic security gates,
radios, railway crossings, TV transmitters,
radar sites, etc.

Do you have heart trouble?

Normal readings are not possible if you
have a heart abnormality that causes
changes in the waveform of an
electrocardiogram, or if you are suffering
from arrhythmia.

Is the watch too far from the chest strap?

The maximum allowable distance between
the strap and watch is about 90 cm (35.4
inches). Communication is not possible
when they are too far apart.

Do you have a hairy chest?

Hair on the chest can interfere with heart
beat detection.

Did more than one minute pass without the
watch detecting any signal from the chest
strap?

This will cause measurement to stop
automatically. Restart the measurement
operation.

Did the battery of the sensor bar or watch
go dead during measurement?

The RECOV indicator will appear on the
watch’s display when its battery is low. If
the RECOV indicator appears frequently,
have the watch’s battery replaced.

If communication is not possible and the
RECOV indicator is not displayed, it could
mean that the sensor bar battery is dead
or that the system is malfunctioning. Take
the watch in to your dealer or CASIO
distributor.

Important!

Data in the watch’s memory will be deleted
when you have the battery replaced.

Is someone nearby using the same type of
watch as this one?

See “Anti-interference Code” for more
information.

Is your heart rate above 90 bpm?

The watch will not calculate energy
consumed unless your heart rate is 90
bpm or higher.

Are your personal information settings
correct?

The watch calculates energy consumed
using your heart rate and personal
information. Make sure your personal
information settings are correct and up to
date.
