Deferred shutdown
In the following cases, automatic shutdown will be deferred if a critical temperature limit is exceeded:
•
while an emergency call is in progress
•
during a two minute guard period after powerup. This guard period has been introduced in order to allow for
the user to make an emergency call. The start of any one of these calls extends the guard period until the end
of the call. Any other network activity may be terminated by shutdown upon expiry of the guard time.
