Restricted dialing

Simrad MS50 provides three choices of controlling calls:

• No restrictions.

• Barred list, which may contain up to 10 phone numbers or part of

numbers that can not be called. F.ex. the entry "0087" in the

barred list prevents all mobile-to-mobile calls.

• Dial from Book only, which restricts calls to the numbers in the

Phone Book (in Simrad MS50). It is still possible to append, i.e. a

short number entry with number field "0047" means that it is possi-

ble to dial all Norwegian numbers. When a SIM card is inserted, the

SIM entries will not be merged with the "phone" entries.

The function is active for non-SIM operation and for one specific SIM

card, see "Restricted SIM usage". It applies to all ports of Simrad

MS50. Only one of the lists can be activated at one time.
