This information is accompanied by the abbreviation TOD.
Depending on the selected unit, the information is displayed
in kilometres (default) or miles and stored in nonvolatile
memory. Under normal operating conditions, this information
cannot be reset.
Automatic trip function (TD)
T
≥
3”: resets LAP and TD.
T < 3”: cycles through the functions.
This information is accompanied by the abbreviation TD and
represents the distance covered by the vehicle in kilometres
or miles (according to the selected unit). It is an automatic
counter which is activated by the first pulse from the speed
sensor. The counter associated with this parameter can be
reset by pressing the button for about 3 seconds while the
TD function is activated until 000.0 is displayed. The reset-
ting of the TD function also resets the LAP parameter. The
TD function can be reset both while riding and when the ve-
hicle is stationary.
Countdown trip function (Countdown)
T
≥
3” and Vel = 0: enters the countdown setting mode.
T < 3” or Vel > 0: cycles through the functions.
This information is always accompanied by a blinking TD
caption. The counter is always active and is automatically
decreased in 0.1 steps (kilometres or miles, according to the
currently selected unit). The parameter can be altered by
pressing the button for about 3 seconds while the Count-
down TD function is activated and the vehicle is stationary.
The different digits that make up the counter can be altered
starting from the most significant digit and proceeding in suc-
cession towards the least significant digit. Pressing the but-
ton for a short time decreases the selected digit by one unit;
pressing it for a longer time makes it possible to select a dif-
ferent parameter. Once the setting is complete, press the
button for about 3 seconds while the least significant digit is
selected to return to the standard operating mode. If the pa-
rameter reaches 000.0, the system sets it to 999.9. After en-
tering the setting menu, if the button is not pressed for 20
seconds, the system will automatically return to the standard
operating mode. Once in the setting menu, if the vehicle
moves off (Vel > 0), the system automatically returns to the
standard operating mode.
SLEEP-MODE
One minute after the last pulse from the speed sensor has
been received or the button has been last depressed, the mi-
crocontroller goes into sleep mode, an operating mode char-
acterized by low power consumption. When the system is in
sleep mode, all activities normally performed by the instru-
ments are suspended, the display and the backlight are
turned off (if the vehicle is not equipped with a battery, the
display and the backlight are automatically turned off when
the engine is switched off). Only the current time continues
to be updated. The system can always go into sleep mode,
independently of the function currently selected.
WAKE-UP (Risveglio dallo stato di Sleep-mode)
The system wakes from sleep mode when:
•
The instrument receives a signal from the speed sensor.
•
The button is pressed.
As soon as the microcontroller wakes up, the following oc-
curs:
• The display and the warning lights are checked (all the warning lights
come on, but only if power is being supplied) for about 2 seconds.
• The selected wheel circumference and number of wheel pulses are di-
splayed for about 2 seconds.
• The function that was displayed before the system went into sleep mo-
de is activated.
If the system wakes up from sleep mode through the electronic trans-
mission (i.e. without pressing the button), the instruments will immedi-
ately switch to the standard operating mode without checking the dis-
play and the warning lights and without showing the selected circumfer-
ence and number of wheel pulses.
