Turning the vehicle’s ignition key to position OFF will turn off the device.
4.1.2.
On/off button
While in off-state, pressing and holding the on/off button will turn ON the device.
While the device is operating, pressing and holding the on/off button for 1 sec will turn OFF the
device.
4.1.3.
Linux shutdown command
The device can be turned OFF by executing Linux shell shutdown commands, for example:
# shutdown
4.1.4.
Forced shutdown
If the device stops responding, a forced shutdown can be performed by pressing and holding the
on/off button until the device is switched off.
The button press response time for the forced shutdown (
long press
) is user configurable
and the default value is set to 8 seconds.
It is
not
recommended to use the forced shut down unless absolutely necessary - since doing so will
immediately switch off all internal voltages, regardless of ongoing operations. Any information
which was not saved to flash memory will be lost when performing a forced shutdown. However, no
physical damage will be caused to the device by a forced shutdown.
4.2.
Light sensor
The
CCpilot VS 12”
contains a light sensor that can be used to automatically adjust the display
brightness, depending on the ambient light conditions. As depicted in Figure 2, the light sensor is
located in the lower left corner of the front surface. When automated dimming is enabled, the level
of sensitivity can be adjusted.
The screen brightness can also be manually controlled directly from user applications through
APIs.
For proper operation it is important to keep the light sensor opening clean and with free visibility.
4.3.
Using the touch screen
To reduce the amount of reflections when operating under sunny conditions, the touch screen’s
protective glass is covered with an anti-glare film. Do not use any sharp or abrasive objects when
interacting with the touch screen.
Basic usage of the capacitive touch screen should be intuitive for most users. Note that the touch
screen is capable of handling two simultaneous touches.
4.4.
Status notification
The LED in the on/off button is used for status notification while starting up, shutting down or in
other operational states. The buzzer may also be used for user notifications. See Table 1 for a
description of the status notification behavior for different operational states.
