Note 1: All three Timers will be turned On or Off simultaneously, so if you just
want to adjust one or two of the Timers, then you should set the time of
the other Timers to zero in Set Mode. The Timer will not be activated
when it is set to zero.
Note 2: When the Interval Timer starts, it will replace the Stopwatch.
Before you begin training, make sure you have synchronized the Heart Rate
Transmitter with the watch. Press “STR” to start free training and enter the Total
Time of free training.

When the watch displays “
LOW BATT
” (as in the figure below), the battery in
your watch needs to be replaced. To maintain its water resistance, professional
battery replacement service is advised. Improper battery replacement or service
will void the warranty. In the case of self replace
ment, removal of the old battery
should be documented in detail to ensure proper replacement of new battery, position
of contacts, and O-ring line-up. To maintain the watch’s water resistance, it is a good
idea to smear a small drop of silicone lubricant spray on the O-ring.
Return to Exercise
HR (Before the
stopwatch starts).
Replacing the Battery
After the first low battery warning comes on for 15 minutes, the EL, Heart
Rate, Humidity & Temperature features will be turned off to conserve
the battery power.

Technical Reference
What is Target Zone Heart Rate Training? To benefit the most from your workout,
you should become familiar with your heart rate training zone. By exercising within
the correct heart rate range, you will achieve your fitness goals and strengthen your
cardiovascular system in less time. Here is basically how it works.
Scientific research has shown that effective conditioning requires that you maintain
your heart rate at the proper level for at least 20 minutes per workout (or per day).
Exercising above you heart rate training zone can be counter-effective. For most
people, as your heart rate exceeds 85% of your maximum Heart Rate, which is the
upper limit, your body begins to become anaerobic and produces acids. At this stage,
your body begins to burn muscle instead of fat. When you have reached the lower
limit of you Target Zone Heart Rate Training, effective conditioning can be achieved.
A heart monitor will tune you in to your body’s internal activity level and helps prevent
injury.
The Hydra-Alert HRM automatically sets the correct Heart Rate Target Limits by
using the American Heart Association standard range of 65% to 85% of the calculated
maximum Heart Rate based on your age. The maximum HR is calculated based
on the equation, max HR = [207 – (Age x 0.7)].
There are various formulas for calculating Heart Rate Target Zones. In most cases,
the formulas provide a range that is the same as or very close to the auto-setting
of
the Hydra-Alert HRM. If you prefer to fine-tune or program your own limits,
this can also be done in the HR Setting Mode. The internal automatic TZ calculation
is based on the following example:
The calculated exercise range for a 30-year-old would be a low of 121 beats per
minute and a high of 158 beats per minute. You should never exercise near your
maximum heart rate (max HR) for any period of time.
Basic Fitness Target Zone & Tips
Depending on your specific goals, individual fitness level or just on how energetic
you feel, you may want to modify your heart rate range from one day to the next
based on the following chart:

Stretch at the beginning and end of every workout. Stretching before your workout
increases flexibility and helps prevent muscle strain or injury. Stretching after your
workout loosens tight muscles and helps prevent soreness.
• Stretch before warm up and after cool down.
• Stretch slowly and gently. Never bounce or stretch to a point of pain.
• Hold each stretch for 30-60 seconds and exhale as you extend into stretches.
Warm Up & Cool Down: 55% or Less of Max. HR
Begin and end every workout with a slow and gradual warm up and cool down,
respectively, Smoothly easing into and out of strenuous activity helps your body
prepare your metabolism and blood flow to efficiently break down fat and change
from one intensity level to another. Going into your Heart Rate Target Zone too
quickly can cause your heart rate to increase too rapidly. Rapid increase of the
heart rate could compromise consistent energy levels during a workout.
• Slowly bring your heart rate to a level just below the lower limit of your Heart
Rate Target Zone.
• Maintain your heart rate at this level for 5 to 10 minutes.
The Fat Burning Zone: 55%-65% of Max.HR
The Fat Burning Zone is recommended for those who are not in adequate physical
shape. This is the ideal zone for those who are beginning to exercise regularly,
would like to loose weight, and are at high risk for heart problems. It is intended
for low intensity and/or long duration exercise. Exercising at a lower intensity allows
for a longer, continuous exercising period. For weight loss and new exercise programs,
l
onger, continuous, low intensity workouts are safer and more beneficial. Slow and
steady wins the race!
• Duration: Build up gradually to 30 to 60 minutes per workout.
• Frequency: Workout 3 or 4 times per week.
The Aerobic Zone: 65%-85% of Max. HR
The Aerobic Zone is recommended for those in good physical condition who
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
from excessive training.
• Duration: 20 to 30 minutes per workout.
• Frequency: At least 3 or 4 times per week.
The Anaerobic Zone is ONLY recommended for to professional athletes or
those in exception physical condition. This zone can also be used for interval
training (high intensity for short durations) to help enhance overall strength and
endurance.
Heart rate fluctuations during physical activity can be tracked and documented
to determine overall health and fitness progress. As the cardiovascular system
becomes stronger, the resting heart rate will decrease. It will require more intensive
physical activity to reach the target zone and less time for the heart rate to recover.
Higher than usual resting heart rate and slower than usual heart rate recovery
could be an indication of strain of the heart from strenuous exercise or dehydration.
Resting for a day, lower intensity exercising, and replenishing the body with fluids
are advised. If your heart rate activity does not return to normal, please consult
a doctor.
The Heat Index combines the effects of heat and humidity. When heat and
humidity combine to reduce the amount of evaporation of sweat from the body,
outdoor exercise becomes dangerous even for those in good physical condition.
Key rules for coping with heat are to drink plenty of water to avoid dehydration,
slow down, and cool off when feeling fatigued, headache, a high pulse rate or
shallow breathing. Overheating can cause serious, even life-threatening conditions
such as heat stroke. The Apparent Temperature, which combines the temperature
and relative humidity, is a guide to the danger. Below is the Heat Stress Index
based on the Apparent Temperature.

Effects of Heat Illnesses
The loss of fluid and salt through perspiration and improper replacement of
them can lead to dizziness and weakness. Body temperature might rise, but
not above 102 degrees. In some cases, victims especially the elderly should
be hospitalized. Heat exhaustion is more likely to occur after continuous exposure
to excessive heat waves. The best prevention from heat exhaustion is to drink
plenty of water and minimize physical activity in the heat. Salt tablets should
not be taken without consulting a physician.
The importance of the Heat Index is to show how hot a particular combination
of heat and humidity feels. The Heat Index in the Hydra-Alert is a report of
the latest weather conditions based on the current temperature and the relative
humidity. Please refer to the following Heat Index Chart to learn about the
Apparent Temperature and to minimize the possibility of getting heat stroke.
If a specific activity is not available in your watch, choose a similar exercise
type and use the corresponding parameter from the table below to set your
watch (Please refer to page 28 to set the MET Parameter).
:e
k
o
rt
staeH
In some cases, extreme heat can upset the body’s thermostat causing body
temperature to rise to 105 degrees or higher. Heat stroke symptoms include
lethargy, confusion, and unconsciousness. Suspicion of heatstroke also requires
immediate medical attention since heatstroke can result in death.
Heat Syncope or Fainting:
Anyone not used to exercising in the heat can experience a quick drop in blood
pressure that can lead to fainting.

Body Fluid Check Monitoring Guidelines and Tips
TM
The ACUMEN Hydra-Alert provides an indication of the level of dehydration.
The purpose of the dehydration reading is to remind individuals to replenish the
body with fluids during exercise.
The thirst mechanism is not precise in humans. An individual can lose fluids
equaling up to 3% of their body weight before a person feels that they need
to quench their thirst.
Most people need more than eight glasses (8 ounces) of water per day. Water
intake each day needs to be half your body weight in ounces. Do not drink
more than 32 ounces at any one time. Water intake should be divided throughout
the entire
day.
If the exercise period is under 60 to 90 minutes, water intake is always appropriate.
If the exercise period is more than 60 to 90 minutes, a sports drink offers an
energy advantage that can enhance stamina and endurance.
Cardiac drift occurs because dehydration causes a drop in blood volume causing
less blood to be pumped with each heartbeat. The heart rate increases 7 beats
per minute for each 1% loss in body weight due to dehydration.
The American College of Sports Medicine on Exercise and Fluid Replacement
(ACSM, 1996) states that adequate fluid replacement helps maintain hydration
and, therefore promotes the health, safety, and optimal physical performance
of individuals participating in regular physical activity.

• Battery Replacement
The Hydra-Alert HRM uses a Lithium CR2032 battery.
To maintain the watch’s water resistance, professional battery replacement
service is advised. Improper battery replacement or service will void the warranty.
In the case of self replacement, removal of the old battery should be documented
in detail to ensure proper replacement of the new battery, position of contacts,
and O-ring line-up. It is a good idea to smear a small drop of silicone lubricant
spray on the O-ring.
