Use by Individuals Who are Sight Impaired
The Amber Alert GPS Product incorporates a very simple four button User interface:
•
SOS Button
•
ON/OFF Button
•
Volume Up Button
•
Volume Down Button
The Amber Alert GPS Product has no display, no keyboard, and no audio or tactile feedback
capability.
The Amber Alert GPS Product is a small, rectangular device. It is approximately 2.8” long, 1.5”
wide and .8” in depth. The most distinguishable feature of the Product is the SOS button located
on the front of the device. The SOS button is large, circular, and indented. The SOS button is
located on the bottom half of the wide rectangular face of the Product. If the device is held with
the SOS button face up and toward the bottom of the device (easily determined by touch), all
other buttons can be easily identified by touch.
The ON/OFF button is located on the top side of the device in the center of the top side.
The Volume Up button is located at the center left side of the device, and the Volume Down
button is located right below the Volume Up button. Both buttons slightly protrude from the
device. A User can hold the buttons down continually to increase or decrease volume, or can
click the buttons and increase or decrease the volume levels incrementally.
In addition, the charging port for the device can be found under a cover at the top left side of the
device (above the Volume Up button). Note: The ON/OFF button and the SOS button must be
pressed and held for at least 5 seconds before their functionality will be invoked. This is by
design to prevent inadvertent use of these functions.
