Determining Your Target Zone
What is Target Zone Heart Rate Training? In order to benefit the most from your workout, you
need to become familiar with your heart rate training zone. By working within the correct range, you
will achieve your fitness goals and strengthen your cardiovascular system in less time. Here is basically
how it works.
Effective conditioning requires that you maintain your heart rate at t he proper level for at least 20
minutes per workout (or per day). At too high of a heart rate your activity can become counter effective.
For most people, as your heart rate exceeds 85% (the upper limit), your body begins to become
anaerobic and produce acids. This also burns less fat which can begin to burn and strain muscles, and
even start storing f at. As f or the Lower limit, this number tells you when you have reached a level of
intensity that is productive. A heart monitor will tune you into your body’s internal activity level and
helps prevent injury or worse.
To make this part easy for you, this monitor automatically sets the cor rect target zone f or you, af ter
you enter in your age in the heart rate setup mode. The inter nal aut o-setting is based on a g enerally
accepted standard range of 65 to 85% of your Max HR (where mHR = 220- Age).
There are many variations of formulas for calculating target zones. In most cases t hey will come up
with a range very close to or t he same as t he auto-setting of t his watch. If you prefer to f ine-tune or
program your own limits, this can also be done in the HR Setting Mode (see page 7). The internal
automatic TZ calculation is based on the following example:
220 - Your Age = Max HR
(For a 30 year old, your calculations would be as follows.)
220 - 30 = 190 Maximum heart rate (mHR)
65% of this number = 123.5
85% of this number = 161.5
Page 6 of 13
The calculated exercise range for a 30 year old would be a low of 124 and a high of 162 beats per
minute.
(You should never exercise near your maximum heart rate (mHR) for any period of time.)
The calculated exercise range for a 30 year old would be a low of 124 and a high of 162 beats per

Stretching- Begin and end every workout with s tretching. Stretching done bef ore your workout
increases flexibility to help prevent muscle strain or injury and stretching af t er, loosens tight muscles
and helps prevent soreness.
• Stretch before warm up & after cool down.
• Stretch slowly & gently, never bounce or stretch to a point of pain.
• Hold each stretch 30-60 sec. & exhale as you extend stretches.
Warm Up & Cool Down, 55% or less - Start every exercise with a slow and gradual warm up and
end with a slow and gradual cool down. Smoothly easing into and out of strenuous activity helps your
body prepare your metabolism and blood flow to efficiently break down fat and c hange over from
one intensity level to another. Going into your target zone too quickly can cause your heart rate to
increase too rapidly causing you to loose your energy too soon, strain yourself or possibly worse.
• Slowly bring your heart rate to a level just below the lower limit of your target zone.
• Maintain heart rate at this level for 5-10 min.
• Maintain heart rate at this level for 5-10 min.
The Fat Burning Zone, 55-65% -This range is recommended for those who haven’t worked out in
a long time, are trying to loose weight, those at a high r isk for hear t problems or if you’re just not
feeling 100% one day. It is intended for low intensity and/or long duration exercise. The lower intensity
helps you maintain your ex ercise for longer periods of time. When exer cising for weight loss or starting
a new exercise routine, longer duration is more important and muc h healt hier than higher int ensity.
• Build up gradually to 30 to 60 min. per workout.
• Workout 3 or 4 times per week.
Page 7 of 13
The Aerobic Zone, 65-85% -This range is recommended for those in good physical condition who
Belt Clip
Belt Clip
have been exercising on a consistent basis for an extended period of time. Exercising at this range
helps improve your fitness level and prevent injury caused from overtraining.
• Duration: 20-30 min. per workout.
• Frequency: At least 3 or 4 times per week.
The Anaerobic Zone, 85%-mHR - To be used by ultra-athletes only and never recommended
without close medical approval or supervision. This range is used only for those in extremely
good physical condition during races or training for competition. It is typically used for interval training
(or short sprints) to help improve or measure endurance levels.
Monitor Your Pr ogress - Track yourself to determine how your overall health and fitness improves
and become aware of your various heart rate levels. As your cardiovascular system im proves, your
normal resting heart rate will decrease. It will t ake longer to reach your target zone, it will t ake less
and less time for your heart rate to come back down after working out.
If you ever notice your resting heart rate to be higher than usual, it may be a good idea to take a rest
from exercise, or at least workout easier that day, Similarly, if you notice that your heart rate doesn’t
come back down as quickly as usual at t he end of your workout, it could be an indication that your
workout was more (or too) strenuous, or that you haven’t recovered well enough from a previous
extraneous workout or injury. These signals in your heart rate could also be an indication of an illness
coming on, stress, or a good reason for a check up with your doctor.
Enjoy your new heart monitor and have fun! We’ll see you at the finish line.
Operating Your Basix
plus
Attaching Your Heart Monitor
1.) Attach the adjustable strap to one side of the transmitter. Push the round tab of the belt clip through
the back side of the attaching hole on the transmitter and twist it into place (Fig. 1). The unique angled
clip is designed to prevent the belt from slipping down your chest. It can be attached in either the up
or down position (keeping both the same). Depending on the contour of your torso, one direction may
be more comfortable than the other.
2.) Adjust the tension of t he strap to fit snugl y but comfort ably, around your chest. Wrap the belt
around your chest as shown (Fig.2).
Fig.1
Elastic
Transmitter
3.) Center and position the belt as shown, at heart level, just below your pectoral muscles or breasts (but not too low) and attach the
other end of the strap to the transmitter. The logo should be positioned at the center of your chest.

4.) Moisten the transmitter electrodes. For best results, the belt should be worn directly on your skin.
Electrodes
A small amount of moisture is needed to assist in conducting the electr ical impulses generated from
your heart beats to the transmitter. Gently pull belt away from skin and
apply a small drop of water or saline solution to each of the two electrodes (one on each side) (Fig.
3).
If you prefer to wear your belt over a light shirt you will need to generously moisten t he areas of t he
shirt directly beneath the electrodes in order to insure proper signal pick-up. You may wear as many
layers of clothing as desired over the transmitter belt without effecting the operating range.
5.) Put your wrist monitor on. The watch doesn’t have to be attac hed to your wrist to regist er your
heart rate it just has to be within 3 feet of your chest.

6.) Heart Rate -From Time of Day mode click MODE button once to go to Heart Rate mode and begin
your exer cise. If your transmitter is correctly attached, the running man indicator on the watch display
should begin to blink and your current heart rate in beats per minute will come up on t he display. If
no heart rate is detect ed f or 5 min. the heart rate circuit will switc h itself off. The “
” indicator tells if
the heart rate circuit is on. To switch it back on after it has shut off, simply restart the Heart Rate mode
by clicking the MODE button.
7.) The Target Zone -Your watc h will provide both a visual indicator (by flashing the heart rate digits)
and an audible alarm (beeping) if your heart rate is above or below your set target zone range. The
”TZ” indicator with t he “
” or “ ” will indicate if your heart rate is within, above or below the
set target zone, respectively. Press and hold the ALARM button to turn the beeping alar m on or of f
(indicated by the “
“ on the display).
8 .) The Stopwatch -From the Heart Rate mode simpl y press the START/STOP button to activate the
stopwatch. You can pause and restart by pressing the START/STOP button. You can also press the
MODE button to view
the Recall or Time modes without interupting the stopwatch. When you have finished, simply press the
STOP button to end the recording. Press the MODE button to proceed to the Recall or Time mode.
*Quick Star t - This feature ins tantly t akes you to the Hear t Rate/Stopwatc h mode and starts or
stops the st opwatch and recordings from any mode, at one simple press of the START/STOP
button.
9 .) Nite-Site night light operation - simply press
the LIGHT button once to light the display for 3 seconds.
10 .) Smart-Light between the hours of 6 PM & 6AM any button press will activate the night light for
2 seconds.
Page 9 of 13
Using the Memory Recall Mode
From the Time mode, click t he MODE butt on 2 times to go t o the Recall mode. The upper display will
show your Tot al Elapsed Time f or your workout and the lower display will show how much time you
have spent in your TZ.
*Smart-Recall Display -This feature allows you to view the Recall display in real time while the stopwatch
is running. To use of during your workout, switch to the Recall mode.
Using the Fitness Index Recording
This feature is used to monitor your fitness efficiency level by monitoring how quickly your heart
rate starts to come back down after your workout. As your cardiovascular system improv es it will
take less and less time for you heart rate to come back down to a resting level after your workouts.
This measurement is automatically activated at the end of your workout when you press the STOP
button. To use it correctly , it’s best to activate it immediately as soon as you have completed your
exercise (or as soon as y ou finish your cool-do wn).When you stop the stopwatch, the display will
automatically switch to the Fitness Index Mode and begin a 60 sec, countdown timer. During this
countdown you should be concentrating on bringing your body down to a comfort able rest, by
taking deep slow breaths and relaxing your muscles. When the countdown timer reaches zero,
the watch will beep twice and display a number between 0 and 99. The higher this number, the
better your recovery rate.
Note: The transmitter belt needs to remain attached to your chest for this feature to work.
Resetting the Stopwatch & Clearing Workout Data
To reset the Stopwatch and clear workout data, press and hold the RESET button for 3 sec, while
in the Heart Rate/Stopwatch mode and with the Stopwatch timer stopped. You will hear a second
beep and the stopwatch timer display will go t o all zeros. This will allow you to record a new
workout starting from zero. Keep in mind that the previous data will remain in the memory recall
displays until it is replaced with new data by restarting t he stopwatch and recording a new
workout.
Troubleshooting
•I can't get a Heart Rate reading? -The most common cause for the heart rate not turning on or
working erratically is that the belt is not positioned correctly or not moistened properly. Make sure that
the belt is positioned high enough on your chest (too high is better than too low) and properly moistened.
The tension should be comfortable but it shouldn’t be so loose that it slides down the chest. Also make
sure that your watch is within the 3f t. transmitting dis tance of t he transmitt er and c hec k t he ang le of
its position (at further dis t ances, the watch face should be parallel and facing t he transmitter, instead
of on an angle).
It is also known that a small percentage of the population may have trouble getting an accurate heart
rate reading with this type of device due to the many various intricacies of t he hear t rate signal. The
signal may be too weak on the surf ace of the skin, stronger in a dif ferent location of the c hest or
irregular in waveform. Also, if the user has had recent heart problems, surger y, or other various
differentiatingfactors, they might have irregularities in HR readings. If you are experiencing difficulties
in picking up a steady signal, you may want to try your monitor on another person, or try positioning
the belt higher on your chest. Shifting it more to the left or right of your chest (instead of centering the
logo) might also work.
Page 10 of 13
•I have a blank screen or missing digits? -This can be an indication of mechanical shock damage,
a dead battery or possibly mois ture damage. If this occurs, you could firs t tr y a Global Reset (see
below) otherwise send it in f or service. Repairs should only be done by Acumen or an authorized
Acumen service center.
*Global Reset -If your monitor should ever get stuck or act erratically due to dropping it, static shoc k
or some other unforeseen reason, this feature will allow you to reset the unit and return all se ttings
back to their inter nal defaults. To perfor m t his function press and hold all 3 buttons at once. Caution:
THIS WILL CLEAR EVERYTHING! including all of your personal settings.
•My heart rate readings act strange while in my car or on an airplane? -Though the Basix
is
designed with high integrity interference elimination circuitry, extremely e x cessiv e electrical or magnetic
fields like those in a vehicle (or on board an aircraft) can cause disturbances in the heart rate readings.
When your monitor detects too much interference such as this, it will usually display ”00” or ”- -” and
eventually turn its heart rate circuit off. The ”
” indicator tells you if the heart rate circuit is on. In
most cases holding the watch within a foot of the front of the chest belt will allow your watch to recieve
the signal and display your heart rate accurately.
My Fitness Index Reads Zero or Low-
This feature tracks how quickly your hear t rate comes down within one minute’s time. If your rate
remains the same, increases, or only decreases by a very small amount within that time, it will produce
a zero (or a low) reading. T o insur e a more accurate measurement, it is important to activate this feature
at the correct time. If you activate it too soon, such as before you have finishing your exercise, there’s
a good chance that your hear t rate could st a y high or increase within t hat time. If you activate it too
late, your heart rate may have already reached it’s resting level and therefor could be higher or nearly
or same within that time,(whic h would also produce a zero or low reading). For best results, activate
the Fitness Index recording as soon as you stop your activity and try to completel y relax during the
countdown recording.
Taking Care Of Your Basix
plus
Y our A cumen Heart Rate Monitor was built with a commitment to quality and dependability. To extend
the life of your monitor and keep it operating at its peak, please read your instructions carefully and
keep the following tips in mind:
Care & Maintenance
•To maximize the life of your heart monitor it is import ant t hat you keep all of its components clean
and always dry of f any moisture before putting it away. For cleaning, use only mild soap and water.
Be careful to never use abrasive cleansers or chemicals as they will cause permanent damage.
•For safekeeping, always store your monitor in its original box and in a safe, mild and dry location.
Be sure not to expose it to extreme temperatures such as, leaving it in direct sunlight or in a hot or
freezing cold car for extended periods of time.
General Precautions
•Although your Heart Rate Monitor is water resistant, be sure not to operate its buttons under water
as pressure can cause them to leak.
•The transmitter will automatically shut itself off once you have disconnected it from your chest. However,
it is important t o thoroughly dry it off after every use, since moisture on the electrodes can cause it to
remain on longer.
Page 11 of 13
•Be sure not to excessively twist or bend the electrode portions of the belt (never bend backwards),
especially when storing it. This can permanently damage their
conductivity and cause mechanical damage to the internal circuit.
Battery Replacement
Should your monitor need battery replacement we recommend that you take it to a local jewelry
store or an authorized Acumen service center in order to guarantee that it will maintain it's water
resistance. Improper battery replacement or service will void the warranty. Repairs should only be
performed by an Acumen service center. Refer to the service card in the back of this instruction manual
