To conserve battery power for Help Calls, the sensors that are used
to detect falls will be disabled when there are approximately 7 days of
battery life remaining. During this time, the HomeSafe AutoAlert Button
will not detect falls. But, it will continue to function as a Help Button,
which you can press if you need help. See battery information section for
more on battery life and replacements.
The HomeSafe AutoAlert Button may not detect every fall
In certain situations, the HomeSafe AutoAlert Button may not detect
a fall. Some movements may not register as a fall and would not be
detected. Examples include, but are not limited to:
• A gradual slide such as from a seated position
• Lowering oneself slowing to the ground (to brace the impact of a fall)
• A fall from a height of less than 20 inches (0.5 meters)
Certain conditions can affect the ability of the HomeSafe AutoAlert
Button to detect a fall:
• If you live at an altitude above 6,600 feet (2000 meters)
• If you are less than 4 feet 6 inches in height (1.4 meters)
• If you weigh less than 88 pounds (40 kilograms)
However, the ability to send a Help Call by pressing the button is not
affected by such conditions.
