Introduction
The Axiom 606 heart rate monitor calculates and displays
heart rate information using a radio frequency signal trans-
mitted from the chest transmitter to the watch receiver.
The Axiom 606 provides the feedback you need to monitor
your training, and the functions you need to increase your fit-
ness and performance.
Combined with an appropriate exercise program, the Axiom
606 will help you:
• Monitor your training
• Reduce your heart rate recovery time
• Increase your aerobic capacity
• Improve your overall fitness
• Improve your exercise performance
The clear display and simple operation make the Axiom 606
very user-friendly.

Button Commands and Important Tips
Button Commands
The Axiom 606 is a full-featured heart rate monitor, but
remains simple to use. You need to remember only a few
basic button commands to set or change values and to scroll
through the four main screens (please refer to Figure A1 and
A2 in the Appendix for an overview of screen selection).
Please note that all button presses should be a short press
and release unless otherwise noted.
To advance from one main screen to the next, press the
Mode button. The Mode button will cycle through the four
main screens in the following order: Time of Day, Stopwatch,
Timer, Time in Zone, and back to Time of Day.
To enter Setup mode: Press and hold the Start/Lap button
in any main screen except Time in Zone. To advance from
one setup screen to the next, press the Start/Lap button. To
change the values within each setup screen, press the Stop/
Adj button.
At any point in the setup mode, you may return to the previ-
ous setup screen with a short press of the Light button. The
backlight will not illuminate in any setup screen. To exit the
setup mode and return to one of the four main screens, press
and hold the Light button.
If you accidentally find yourself in a setup screen but don’t
wish to modify the values, simply press and hold the Light
button to exit the setup mode and return to a main screen.

Important Tips
1. To activate the Heart Rate function (to display heart rate),
press and hold the Mode button in any main screen.
2. To exit any setup screen and return to a main screen,
press and hold the Light button.
3. To advance from one main screen to the next, press the
Mode button.
4. To start the Stopwatch in any main screen, press the Start
Lap button. To stop the Stopwatch in any main screen,
press the Stop/Adj button.
5. Time in zone data accumulates only while the stopwatch is
running. Activate the stopwatch at the beginning of your
workout if you wish to record time in, above and below
zone, and average and maximum heart rate for entire
workout.
6. For heart rate readings to register properly, it is critical
that there be sufficient moisture (water, saliva or Axiom
Heartbeat Signal Enhancer) between the electrodes on the
transmitter (chest strap) and your skin. Insufficient
moisture may cause no reading, a frozen reading or
an erratic reading.
7. Using a wireless heart rate monitor near computers,
motorized gym equipment, electric motors, high voltage
power lines, automobiles, televisions or fluorescent lights
may cause erratic readings.

6
8. Your Axiom heart rate monitor is water resistant, and can
be used while swimming. However, do not press any of the
buttons while the receiver (watch) is submersed.
Positioning the Chest Band/Transmitter
1. Adjust the elastic strap length to achieve a snug,
comfortable fit.
2. The transmitter should face outward as shown in Fig.2,
with the band fitting comfortably on the bare chest just
below the breast.
3. Center the transmitter on the chest (with the Axiom
logo right-side up).
Figure 2. Correct Transmitter
location on chest, detail of
moistening electrodes.

4. Moisten the rubber electrodes on the inside of the
transmitter strap with water, saliva or Axiom Heartbeat
Signal Enhancer.
5. Attach the receiver to your wrist, or mount it to your
bicycle (see instructions below for mounting the receiver
to your bike).
6. When placed on the body, the transmitter is automatically
activated (and deactivated when removed). To conserve
transmitter battery power, the transmitter should be
removed when not in use.
If you have difficulty obtaining a regular heart rate reading,
try readjusting the chest strap. The rubber electrodes must
be flat against the skin, and the band must be in the correct
position—not too low. Make sure there is sufficient moisture
between the electrodes and your skin. Check that the band
is clean, with no accumulated sweat or dirt.
Mounting the Receiver to Your Bike
Your 606 includes a Handlebar Adapter for your bike. Slide
the split foam ring over your handlebar in a
convenient location and wrap the Velcro®Strap snugly
around the foam ring. Your 606 receiver may now be
attached to the foam ring as it would be attached to your
wrist.

A maximum heart rate (MHR) value must be entered in order
for the 606 to calculate and display current heart rate as a
percentage of maximum heart rate.
In the Maximum Heart Rate setup screen, you may enter
either your age or your maximum heart rate (if known).
Values between 10 and 99 will be interpreted as age values,
and “AGE” will appear next to the value. The HR600 will cal-
culate an approximate maximum heart rate value based on
your age according to the following formula:
MHR = 220 – AGE
Values between 121 and 220 will be interpreted as maximum
heart rate values, and “MHR” will appear next to the value.
Values between 100 and 120 will not be displayed.
1. “AGE” or “MHR” and a flashing age or MHR value will
appear in the lower row of the display.
2. Short presses of the Stop/Adj button will increase the
value, while short presses of the Mode button will
decrease the value. A long press of the Stop/Adj button
will cause the value to increase rapidly, and a long press

a long press of the Mode button will cause the value to
decrease rapidly. In the lower right corner of the display,
the upper limit value is displayed as a percentage of
maximum heart rate.
2. Press the Start/Lap button to select the lower limit value
for Zone 1. The lower limit value will flash. Use the Stop/
Adj and Mode buttons to set the lower limit value in single
beat increments (from 30bpm to the upper limit value

14
minus 5bpm). In the lower right corner of the display, the
lower limit value is displayed as a percentage of maximum
heart rate.
Note: The 606 will automatically compensate to preserve a 5
bpm difference between the upper and lower limits.
3. Press the Start/Lap button again to select the upper limit
value for Target Zone 2. The number “2” and a flashing

The 606 automatically records the amount of time it takes
your heart rate to descend from a preset upper limit to a pre-
set lower limit. Timing begins automatically when your heart
rate falls below the upper limit, and continues until your
heart rate falls below the lower limit. During recovery tim-
ing “RCY” will flash in the upper row of the display screen.
When timing stops, the Heart Rate Recovery alarm will sound
(if activated—see “Alarms” p.23), and recovery time will
appear in the upper row of the display for 5 seconds. While
the recovery timer is running, accumulating recovery time
can be viewed in the Recovery Timer recall screen. (See
“Viewing Memory Recall screens”, page 34).
Note: Recovery timing is automatically disabled when the
Interval Timer is in use.
1. “RCY” will appear at the top of the display, and the upper
limit value will flash in the upper row of the display.
2. Short presses of the Stop/Adj button will increase the
value (from 35bpm to 200bpm), while short presses of the
Mode button will decrease the value. A long press of the
Stop/Adj button will cause the value to increase rapidly,
and a long press of the Mode button will cause the value
to decrease rapidly. In the lower right corner of the dis
play, the upper limit value is displayed as a percentage of
maximum heart rate.
3. Press the Start/Lap button to select the lower limit value.
The lower limit value will flash in the lower row of the
display.

4. Use the Stop/Adj and Mode buttons to set the lower limit
value (from 30bpm to the upper limit minus 5bpm). In the
lower right corner of the display, the lower limit value is dis-
played as a percentage of maximum heart rate.
Note: The 606 will automatically compensate to preserve a
5bpm difference between the upper and lower limits.
5. A further press of the Start/Lap button will advance to the
Timer setup screen. Or, to exit the setup mode, press and
hold the Light button.
Setting Stopwatch/Lap/Interval Timers
See Figure A5 in Appendix.
Note: This setup screen can be accessed at any time from
the Timer (TMR) main screen with a long press of the Start/
Lap button.
The 606 allows you to select one of three timer options, a
Stopwatch Timer, Lap Timer or Interval Timer. During exer-
cise, one of the three timer options must be activated in
order for heart rate data to accumulate in memory.
The Stopwatch Timer (StP) operates as a standard stop-
watch, allowing you to time any event, or a portion of any
event.
The Lap Timer (LAP) is used to time as many as 20 laps (por-
tions of a workout) and to record the average and maximum
heart rate for each lap.
