Button Commands and Important Tips
Button Commands
The Axiom HR600 is a full-featured heart rate monitor, but
remains simple to use. Remember only a few basic button
commands to set or change values and to scroll through
the four main screens (please refer to the diagram on pages
____ 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 advance 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
Adjust button.
At any point in the setup mode, you may return to the pre-
vious 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 Stop/Adj 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. 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 mois-
ture may cause no reading, a frozen reading, or an erratic
reading.
6. Time in zone data accumulates only while the stop
watch 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.
54

7. Using a wireless hear rate monitor near computers,
motorized gym equipment, electric motors, high voltage
power lines, automobiles, televisions or fluorescent lights
may cause erratic readings.
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 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).
4. Moisten the rubber electrodes on the inside of the trans-
mitter 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 automati-
cally activated (and deactivated when removed). To con-
serve transmitter battery power, the transmitter should be
removed when not in use.
If you have difficulty obtaining a regular heart rate read-
ing, 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 HR600 comes with a Handlebar Adapter for your bike.
Slide the split foam ring over your handlebar i a convenient
location and wrap the Velcro® Strap snugly around the
foam ring. Your HR600 receiver may now be installed over
the foam ring as it would be attached to your wrist.

In Lap Mode
To use the Lap Timer, Lap mode must have been selected in
the setup procedure (see “Setting Stopwatch/Lap/Interval
Timers”).
Note: Lap Timer and stopwatch operation are linked.
The lap timer is used to record times for as many as 20
laps (portions of a workout). Also recorded are average
heart rate and maximum heart rate for each lap, and the
time of day that the first lap was begun.

1. Advance to the Timer main screen using the Mode but-
ton. “TMR” and current lap time will be displayed in the
upper row of the display. If the heart rate function is acti-
vated, the lower row of the display will show the number
of the current lap for three seconds, before reverting to
current heart rate information. If the heart rate function is
not activated, the number of the current lap will remain
displayed.
2. To begin the first lap, press the Start/Lap button.
(Note: This press can be made from any main screen.)
This press will activate the stopwatch, and “STW” will flash
in all main screens (except the Stopwatch main screen,
where it will remain steady).
3. To record the first lap, press the Start/Lap button.
(Note: This press can be made from any main screen.)
One alarm beep will sound, and the lap time, average heart
rate, and maximum heart rate for lap 1 will be recorded in
memory.
4. To measure successive laps, press the Start/Lap button.
(Note: These presses can be made from any main screen.)
Each press of the Start/Lap button records the previous lap
in memory and begins a new lap.
5. Each time the Start/Lap button is pressed, the time of
the lap just measured will be displayed in the upper row of
the display, and the number of the lap just measured will
be displayed in the lower row of the display. After three
seconds, the display will revert to current lap time and
heart rate information.
6. After the 20th lap has been recorded, a further press of
the Start/Lap button will display “End” to indicate that
memory is full. The stopwatch will continue to run, but no
additional lap data will be recorded in memory.
Each lap time will be recorded in memory (up to a total of
20 laps), along with average and maximum heart rate val-
ues for each lap (provided the heart rate function is acti-
vated), and total elapsed stopwatch time. To view this
recall data, see “Viewing Time
In Zone Recall Data.”
7. To reset the Lap Timer and Stopwatch, advance to the
Timer main screen using the Mode button.
8. Stop the stopwatch (if it is running) with a short press
of the Stop/Adj button.Press and hold the Stop/Adj but-
ton.

In Interval Mode
To use the Interval Timer, Interval mode must have been
selected in the setup procedure (see “Setting
Stopwatch/Lap/Interval Timers”).
Note: (Interval Timer and stopwatch operation are linked.)
To operate the Interval Timer, the heart rate function must
be activated (with a long press of the Mode button in any
main screen).
The interval timer is used to control interval training, by
coordinating an alternating sequence of up to 20 exercise
phases and 20 recovery phases. Each exercise phase lasts
for a preset duration, and is governed by a countdown
timer. Each recovery phase lasts either for a preset dura-
tion, or until a preset recovery heart rate is attained. (To
program the exercise and recovery sessions, see “Setting
Stopwatch/Lap/Interval Timers.”)
1.( ) Advance to the Timer main screen using the
Mode button. The “TMR” icon and time remaining in the
first exercise phase of the first interval will be displayed in
the upper row of the display. If the heart rate function is
activated, the lower row of the display will show the num-
ber of the current interval for three seconds, before revert-
ing to current heart rate information. If the heart rate
function is not activated, the number of the current inter-
val will remain displayed.
2. Beginning the first interval session requires two presses
of the Start/Lap button. (Note: These presses can be made
from any main screen.) (Note: These presses can be made
from any main screen.) The first press will activate the
stopwatch. “STW” will flash in all main screens except the
Stopwatch main screen, where it will remain steady.
3. The second press of the Start/Lap button will begin the
exercise phase of the first interval. This press can be made
from any main screen. If this press is made from any
screen other than the Timer main screen, the HR600 will
automatically advance to the Timer main screen, and the
running countdown timer will appear in the upper row of
the display.
4. The beginning of each exercise phase is signaled with
one alarm beep. As each exercise phase begins, the time
remaining for that phase will begin to count down in the
upper row of the display, and the number of the current
interval will be displayed briefly in the lower row of the
display.
5. Timed Recovery: The beginning of each recovery phase
is signaled with two alarm beeps, and “RCY” will flash at
the top of the display. As each recovery phase begins, the
upper row of the display will show a countdown timer that
indicates time remaining in current recovery phase. (To
select timed or heart rate-governed recovery, see step 12
of “Setting Stopwatch/Lap/Interval Timers.”)

Heart Rate-governed Recovery: The beginning of each
recovery phase is signaled with two alarm beeps, and
“RCY” will flash at the top of the display. As each recovery
phase begins, the upper row of the display will show a
standard timer, which indicates time accumulated in the
current recovery phase. (To select timed or heart rate-gov-
erned recovery, see step 11 of “Setting
Stopwatch/Lap/Interval Timers.”)
6. The end of the interval session (the end of the last
recovery phase) is signaled with three alarm beeps. (To
activate or deactivate this alarm, see “Interval Alarm.”on
