6. CLOCK FUNCTION
The clock which shows time is synchronised to the GPS signal from satellites, although only minutes
and seconds are synchronised leaving the user to set hours at least once. After powering up and
changing the left screen to km/l ,the message GPS appears on it which indicates waiting for the satellite
signal, whereas on the top screen the operating system version is displayed.

In order to set proper time we must hold both buttons simultaneously for a few seconds until the hour
figure starts blinking. Then we use the left (down) and the right (up) buttons to adjust hours.
After setting proper time we must press again both buttons simultaneously, this time shortly, to make
the minute read-out blink and if we don't wish to modify them (because the value is correct from
the GPS signal) press both buttons again to exit the procedure of time setting. If the satellite signal
is unavailable, minutes must be set in the same way as hours.
7. FUEL ECONOMY INDICATOR
This indicator is visible on the left screen
when the icon “km/l”is displayed. The indicator
provides essential information from the
fuel consumption point of view, determining
the efficiency of the boat
operation. On the basis of data from the fuel
consumption measured byfuel sensor as well
as the boat's speed measurement from GPS – the
fuel consumption indicator is calculated. It defines
the distance (in km)which can be covered on
one litre of fuel. The bigger the indicator is,the longer
distance can be covered on a specified amount of fuel,
so in order to sail efficiently one must aim to maximize
the value of thisparameter by changing trim settings
and rotation speed of the motor.

Within several seconds to a few minutes (depending on the history of previous start ups of the device)
the message GPS should disappear and the actual minute time ought to appear in minute position.
Then we can manually set the correct time which will be remembered as the time zone
for the GPS operation.
