Description
0×03
IgnitionOffShutdownTime is a
period of time (in minutes)
during which MWService waits
before shutting down in the case
of an ignition power key off
event. For example, if the value
of this parameter is 4 and
MWService receives notification
about an ignition power key off
event, it prints a message box
on the screen, waits for four
minutes and then shuts down
MW-520.
0×03
DisplayOverheatShutdownTime
is a period of time (in minutes)
during which MWService waits
before shutting down in the case
of display overheating. For
example, if the value of this
parameter is 5 and the
temperature of the MW-520
display becomes critical,
MWService prints a message
box on the screen, waits for five
minutes and then shuts down
MW-520.
This parameter enables clients
to cancel handling of an ignition
power off event by MWService.
In the case that no other clients,
except MWService, have
registered for an ignition power
event, MWService always
handles the ignition. Otherwise
(if another client has registered
for an ignition power event), the
value of
IgnitionExclusiveRegistration is
relevant: if the value is 0,
MWService handles the ignition
power event; if the value is 1, it
does not.
