Setting Items
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 replacement, 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.

3.1 Getting to know Heat Index
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
Heat Cramps:
Exercising in hot weather can lead to muscle cramps, especially in the legs,
because of brief imbalances in body salts. Cramps become less frequent as a
person becomes used to the heat. As with heat cramps, the cure is to take it
easy.
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.
Heat Exhaustion:
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.

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.

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 TM 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.

3.2 Determining Your MET Parameter
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 11 to set the MET Parameter).
TM
Body Fluid Check Monitoring Guides and Tips
The ACUMEN Hydra-AlertTM 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.
3.3
Table of MET Parameter
Intensity Level
Exercise
It takes the human body 12 to 24 hours to replace fluids from heat and
exercise. To prevent the harmful effect of excessive dehydration it is
necessary to drink before you become thirsty.

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.

Strength and endurance are reduced by 10-15% after just a 2% loss of body
weight through dehydration.
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

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
