Sleep-Mode And Wake-Up - Beta ALP 4.0 Bedienungsanleitung

7. START-UP (SYSTEM START-UP)
When the instrument is switched on, the
system displays a range of information
for the user which, to make things easier,
is represented on the following screens
(pages):
• 1st page (at every connection with vehi-
cle battery): Software version and date of
issuing (for approx. 3 seconds) (fi g. 17).
• 2rd page (every time the instrument is
switched on): Check of all Icd segments
for approx. 3 seconds (fi g. 18).
• 3rd page (every time the instrument is
switched on): Display of set parameters
(fi g. 19).
During these screens the system carries
out a check of all indicator lights and
backlighting: all LEDs are switched on
and then are switched off at the end of
the display check.
Once the above is fi nished, the system
passes to normal display.

8. SLEEP-MODE AND WAKE-UP

SLEEP MODE - The microcontroller enters the sleep phase, characterised by low power
consumption when the shift position switch is in the OFF position.
To conserve power during sleep mode, every operation normally carried out by the
instrumentation is suspended; the display and its backlighting are switched off and only
the updating of the current time remains active.
Sleep mode is always possible, irrespective of the function selected.
WAKE-UP - Wake-up from sleep mode occurs when the shift position switch is in the
ON position.
The following occurs immediately after wake-up of the microcontroller:
• Display and signal indicator check for approx. 3 seconds
• Screens displayed as shown in fi g. 17 and fi g. 19 for approx. 3 sec.
• Activation of the last function displayed before the system went to sleep and enablement
of all functions.
