certain time interval. Profile 3 can either contain operator codes (rarely used) or have an empty
list. Profile 4 is not used (profile 4 can only be used when FM5500 encounters a 'panic' priority
event (see 7.2 chapter)).
In the example (Figure 44) FM5500 connects to operator with code 24702. It checks profile
1 operator list, but there is only one operator code entered which does not match. Then it checks
profile 2 operators list. This code is entered there, so FM5500 switches to profile 2.
If there are no operator codes entered in all profiles after operator search task FM5500 will
check all 3 profiles and won’t find any operators in any list. In such a case, FM5500 will switch to
profile 3. Note that before switching to profile 3, the device closes the GPRS session.
Operator search is performed every 15 minutes. If no operators are entered in
any profile it can have influence on GPRS sessions. IF GPRS sessions are
attaching/detaching every 15 minutes it means configuration of FM5500 is
performed incorrectly.
