Button Commands and Important Tips
Button Commands
The Axiom HR150 offers a variety of functions, yet is simple
to use. You need remember only a few basic button com-
mands to set or change values and to scroll through the
four main screens.
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, Daily
Alarm, Stopwatch, Time in Zone, and back to Time of Day.
Please note that all button presses should be a short press
and release unless otherwise noted.
To enter setup mode: Press the Select button in any main
screen except Stopwatch. To advance from one setup screen
to the next, press the Select 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 Return button.
To exit the setup mode and return to one of the four main
screens, press and hold the Return button.
The following instructions explain the complete setup pro-
cedure for all functions. If you’d like to program a single
function, advance to the main screen for that function
using the Mode button, and then press the Select button.
Axiom HR-150 instr 2/19/2001 5:37 PM Page 3

Within each setup screen, short presses of the Adjust
button will modify the values shown. To exit the setup
mode and return to a main screen, press and hold the
Return button.
If you accidentally find yourself in a setup screen but don’t
wish to modify the values, simply press and hold the Return
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
except Daily Alarm.
2. To exit any setup screen and return to a main screen,
press and hold the Return button.
3. To advance from one main screen to the next, press the
Mode button.
4. 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.
5. Using a wireless heart rate monitor near computers,
motorized gym equipment, electric motors, high voltage
Axiom HR-150 instr 2/19/2001 5:37 PM Page 4

5
power lines, automobiles, televisions, or fluorescent lights
may cause erratic readings.
6. 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 Strap/Transmitter
1. Adjust the elastic strap length to achieve a snug, com-
fortable fit on your chest as shown in figure 2.
2. The transmitter should face outward as shown, with the
strap fitting comfortably on the bare chest just below the
breast.
Figure 2 Correct Transmitter
location on chest, detail of
moistening electrodes.

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 use 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 automat-
ically 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 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 strap is clean, with no accumulated sweat or dirt.
Mounting the Receiver on Your Bike
Your HR150 comes with a Handlebar Adapter for your bike.
Slide the split foam ring over your handlebar in a conve-
nient location and wrap the Velcro® Strap snugly around
the foam ring. Your HR150 receiver may now be installed
over the foam ring as it would be attached to your wrist.

Replacing Batteries
Transmitter Battery
(Battery Type: 3V Lithium 2032)
To remove the battery compartment lid, insert a coin into
the slot on the lid, and turn counterclockwise (see Figure
8). Before removing the battery, note its orientation. The
positive pole should face the compartment lid, and the
negative pole should contact the metal prongs inside the
battery compartment. Orient the replacement battery in the
same manner. To ensure continued water resistance, make
sure the rubber O-ring is still in place around the edge of
the lid before reinstalling.

Troubleshooting
What if the heart rate reading is erratic or
totally absent?
1. Make sure the chest strap is sufficiently tight. The strap
should be positioned and tightened so that the electrodes

are flat against your skin. Adjust the strap side to side or
slightly up or down until the strap is positioned properly,
and the electrodes make solid contact with your skin.
2. Make sure the electrode strips are sufficiently moist.
Moisture enables the electrodes to make proper electrical
contact. Moisten the electrode strips with water, saliva, or
Axiom Heartbeat Signal Enhancer.
If you are wearing the transmitter strap over a shirt, make
sure the shirt is moistened to provide adequate electrical
contact for the electrodes.
Accumulated sweat or dirt on the electrode strips may
impair electrical contact. Be sure the electrode strips are
clean.
3. Make sure you have activated the heart rate function
with a long press (press and hold) of the Mode button in
any of the main screens except Daily Alarm.
4. Make sure the transmitter battery is installed properly
and fully charged.
What if the heart rate reading becomes extremely high
(above 200)?
Electromagnetic signals from outside sources may cause
abnormally high heart rate readings. Common sources of
electromagnetic signals include high voltage power lines,
