TUNING
While sitting in the normal driving position, power up the EA410.
After two seconds the EA410 will emit a power-on tone and light
the STATUS INDICATOR for one second, after which the STATUS
INDICATOR will either dim, flicker, or go off -- depending upon
the extent to which the EA410 recognizes the driver’s eyes.
Adjust
the pan and tilt of the EA410 unit to maximize the
amount of time that the STATUS INDICATOR remains on.
ALERT STATUS
To be able to perform its function, the EA410 requires a brief
period to become familiar with the driver’s face before entering
ALERT status. For most drivers, the EA410 will enter ALERT
status after about a minute or so of normal driving. For drivers
that wear eyeglasses, the unit may take as long as 5 minutes to
enter the ALERT status. Thereafter, the EA410 will respond
within two seconds to signs of fatigue or inattention
WARNING METHOD
Upon detecting signs of fatigue or distraction, the EA410
verbally warns the driver to “Pay Attention to the Road” while
simultaneously setting the WARNING data output low for a few
seconds.
If the driver brings his gaze back to the road or to the EA410
immediately, the EA410 resets and is armed to warn again in 10
seconds. However, if the driver fails to respond quickly to the
warning, the EA410 will set off an alarm sufficient to startle the
driver.
