11. BATTERY VOLTAGE
Battery voltage is indicated on the right screen , when the icon “V” is displayed. It should be
remembered that the displayed value is also averaged due to the fact that sharp voltage hikes
are not visible.
12. SCREEN ILLUMINATION
In order to illuminate the screen the left button must be pressed while voltage is being displayed
on the right screen. To switch illumination off we must press left button again while voltage is also
being displayed on the right screen.
13. OFF SWITCH
There are a few methods to switch the device off. The first one is to remove the power supply.
The second one is by using the right button after switching the right screen into OFF mode.
The third one by automatic switch off. The first method has a disadvatage
which is loosing the start
data of GPS and a long restart of GPS system (lasting up to a few minutes). In case of switching
off with right button or automatic switch off this problem won't take place and the start-up is much
shorter. In order to perform switching off with the button, first we must press the right button until
the message OFF is displayed on the right screen. At this moment hold the right button for a few
seconds until the message OFF disappears from the screen. From this moment the device is
switched off but stays in ready mode of the GPS system with minimal power consumption (3mA).
Automatic switch off takes place after 12 hours of the lack of input pulses from Tacho or fuel sensor.
To start the device again press any of the buttons.
