Information is Power
By measuring intensity (heart rate /pace) and
duration (time) you can avoid over training,
help prevent injury, and maximize your
chances of achieving your goals.
triax cv10 features
• Accurate heart-rate and pace data
• Digital transmission
• 100 lap memory
• Programmable training zones
• View button for quick access to key info
• Automatic lap measurement
• Data: timing information, time in zone,
average pace and average heart rate
for each lap/run.
• Time /Day /Date/Alarms
HR transmitter
The Heart-Rate transmitter reads heart-rate
information when worn directly against the
skin and within a few meters of the watch.
The HR transmitter is ergonomically designed
to fit comfortably during all types of exercise.
SDM pod
The SDM (Speed Distance Monitor) pod
measures foot acceleration/deceleration
100 times per second. When properly
calibrated, the pod accurately calculates
speed and distance even if stride length
and running pace changes.
ATTENTION: Anyone beginning an exercise
regimen for the first time (especially users
of pacemakers or other implanted devices)
should consult a physician or health
professional before using the Triax cv10.

Press down tab
until flush.
Attach other side of HR
transmitter around chest.
Position on rib cage just
below the breast plate.
The transmitter should be
worn directly against skin
and snug enough to stay
in place during workout.
Generously wet both
sensors on the back
of the HR transmitter
to ensure strong
connection between
your pulse and the
transmitter.
Remove the top
strap and unseat
the SDM pod from
the bottom clip.
Loosen shoe laces
and slide pod clip

Once calibrated, the Speed Distance Monitor (SDM) pod is more than 97% accurate for most runners. Calibrate the SDM
pod by running 400-800 meters on a marked track, then adjust the watch to exact distance. The SDM pod will need to be
calibrated each time you replace the watch battery. Go to a 400-meter marked track and follow steps through to
automatically calibrate the SDM pod.
Turn SDM pod ON by pressing the power button
until LED begins to blink.
Scroll to
RUN mode.
Press several times
to scroll to CALIb.
400 meters
Run at your usual pace on the inside
edge of the track. Complete 1-2 laps
(400-800 meters).
Push START
and begin
running. Push STOP
when finished.

Manually Calibrate the SDM Pod
After calibration, the SDM pod automatically
calculates an offset value. The default value is 1.000.
Change the offset value to make small adjustments to
the calibration. If the SDM pod is slightly under measuring
a known distance, increase the offset value. Different shoe
models may affect the pod calibration. Adjust the offset value
accordingly if you notice differences between shoes.
Follow steps through to fine-tune the offset value.

If you ran 800 meters, adjust displayed
distance to read 800m.
Press several

Scroll to
RUN mode.
EXAMPLES
1.000 = factory setting
0.990 = 99% of factory setting
1.010 = 101% of factory setting
The offset value is 1.000.
You run 400m. The SDM pod
returns a reading of 380m (5%
under). The offset value should
be adjusted to 1.050 (5% above).
NOTE: Write down and save your
offset value. It will come in handy
if you let friends or family borrow
the Triax CV10 and they
change the calibration setting.
Press to change value.

for each lap/total period. After you stop the chronograph,
you can save your run information and review it in
DATA mode. See page 15 for DATA mode.

210 - (0.7 x age)
Light Intensity
(60-70% of Max HR)
Exercise in this range at the
start of a workout or to recover
from a tough workout or race.
You should be able to easily
maintain a conversation while
exercising at this intensity.
Moderate Intensity
(70-80% of Max HR)
Exercise in this range to develop
endurance and prepare your
muscles to make the transition
from aerobic to anaerobic.
You should be able to maintain
this for a while. You should not
be completely breathless and
this should not hurt.
Heavy Intensity
(80-90% of Max HR)
Exercise in this range
to increase muscle strength
and improve your anaerobic
threshold. This is uncomfortable.
You should be breathing very
heavily. You should only be able
to sustain this for a brief time.
Maximum Intensity
(90-100% of Max HR)
Exercise in this range to increase
mental toughness, Max V02 and
tolerance to lactic acid. This is
very uncomfortable. You can
barely sustain it. You should be
completely breathless. Do not
exercise at this intensity except
on the advice of a trained
medical professional.

Press and hold the power button on the SDM pod for five seconds
until the LED light begins a fast triple-flash. The pod is now in ID
mode, ready to link with the watch. After 10 seconds the pod will
revert to normal operation.
NOTE: If you are unable to enter SDM LINK OK screen before
the 10 seconds expires, turn the pod off and repeat step 3.
Firmly grasp the HR transmitter with both hands, one on
each end, making sure to touch the sensors on the back side
of the transmitter. There is no ON/OFF switch for the transmitter.
It sends a digital signal during the first 10 seconds of connection
with the sensors.
NOTE: If you are unable to enter
HRM LINK OK screen before
the 10 seconds expires, wait two minutes
for the HR transmitter to automatically
turn off and try again.
After a few seconds the watch should display SDM LINK OK
and HRM LINK OK. The watch has located the digital ID of the
HR transmitter and will store the ID until you either change
the watch battery or reset the watch.

Linking the Digital Components to the Watch
The HR transmitter and SDM pod have unique digital IDs to avoid crosstalk with other components. Before your
components can communicate properly, the watch must be linked to the transmitter and pod to establish and share
this ID. The original transmitter which came with the watch was linked at the factory. Once linked, the digital IDs are
stored by the watch until you change the watch battery or reset the watch. Follow steps through to re-link
the original or any replacement components to the watch.

SENSORS

HR transmitter does not link with the watch:
Make sure the watch has assigned a digital ID
to the HR transmitter. See page 18.
Make sure the HR transmitter is ON by placing it on the body.
The unit turns ON when it detects the two electrodes on the
body. It is recommended to wear the transmitter directly
against the skin.
Reposition the HR transmitter slightly.
Try replacing the battery. See page 21.
Check battery placement for correct orientation. See page 21.
Moisten the electrodes with water or gel to make better
contact with the body. If you are wearing the HR transmitter
over clothing, try wetting the clothing.
Heart rate reading on watch is erratic or stops:
You may need to replace the battery in the HR Transmitter.
Sources of electromagnetic fields like appliances,
computers and power lines can cause interference.
Change your location.
This product complies with EN60601-1-2
Watch display is frozen:
The display of your watch may "freeze" due to static
electricity or recent battery replacement. If this occurs,
press and hold all four buttons at the same time.
This will erase the data in the memory and allow you
to reset the watch to the factory settings.
Watch beeps continuously:
If you have the zone alarm on and your heart rate or pace
does not fall within any of your zones, the watch will beep
to indicate you are out of your zones. See page 10 for
instructions on how to turn off the zone alarms.

Troubleshooting
SDM pod does not link with watch:
Make sure the watch has assigned a digital ID
to the SDM pod. See page 18.
Be sure the unit is ON by pressing the power switch
on the top of the unit until the LED begins to blink.
Try replacing the battery. See page 21.
Check battery placement for correct orientation. See page 21.
LED light on SDM pod flashes rapidly:
This indicates low battery power.
Replace the AAA battery in the SDM pod.
Cross-talk:
If you receive “cross-talk” from another electronic device,
press the button on the speed sensor. The watch and speed
sensor will begin linking on another channel.
SDM pod attachment to shoe:
Make sure the SDM pod is attached to the laces securely
enough so there is no wobble when running. The pod should
be aligned with the foot and secured well enough that the
alignment does not change during run.
Orthotics:
People who wear orthotics or have extreme pronation or
supination in their stride may experience reduced accuracy.
Re-calibrate for improved accuracy.
Varying paces:
People who run at varying paces within a run
may experience reduced accuracy.
Calibrate at the speed you usually run for improved accuracy.
Press and hold all four side buttons
at the same time to reset
the watch to the factory settings.
