Replacing the Battery 9.2
MT
When the watch displays “
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
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.
Note:
Humidity & Temperature features will be turned off to conserve the
battery power.

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,
ecnerefeR lacinhceT
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.

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 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.

Body Fluid Check Monitoring Guides and Tips

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.
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
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.

If your monitor should ever get stuck or act erratically due to dropping it, static
shock or some other unforeseen reason, the Global Reset feature will allow
you to reset the unit and return all settings back to their internal defaults. To
perform this function, Press and Hold all four buttons together for 3 seconds
under any mode (display all LCD). The unit will automatically reset and return
to initial setting mode.
Caution: Global Reset will RESET ALL FUNCTIONS BACK TO ORIGINAL
FACTORY SETTINGS including your Personal Settings.
• Battery Replacement
The Hydra-Alert JR 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.
