11. SLEEP-MODE AND WAKE-UP
11.1. Sleep mode
The microcontroller enters the
sleep-mode
phase, with
low current absorption, when the key is turned off.
To reach this aim, during sleep mode phase, every activi-
ty will be interrupted, the display and its backlighting will
be off, only the update of current hour is on Sleep-mode
phase can always be reached, regardless from selected
function.
11.2. Wake-Up
Awakening from
Sleep
mode phase occurs when the key
is turned ON.
Immediately after the microcontroller awakening follo-
wing activities happen:
• Check of the display and of lights for about 2 seconds.
• Visualization of selected wheel circumference, of
wheel turns impulses, of unit of measurement and
of graphic bars for about 2 seconds (see picture 10-3).
• Starting of last visualized function before sleep mode
status and qualifi cation of all functions.
12. FIRST INSTALLATION OF DEVICE
Default values of the device:
• Circumference: 1.845mm
• Measurement unit of distance: km/h for speed and
km for distance
• Turn wheel/impulses: 6
• Turn engine/impulses: 4
To modify one of these parameters You have to
follow the procedure as in Set-up menu paragraph.
During fi rst installation of device the display always
shows the updated software version and date.
