12. LOCKING FACILITY
13. OPTIONS
This feature is available on the SA54L5. Pin 11 (LOCK) should be connected to V
if the device is to be locked and to V
can be controlled by an inexpensive low voltage SPDT switch. When locked it is
impossible to dial out any number other than those stored in the LNR and repertory
memory. If the redial key is pressed twice while in the locked state the number in the
LNR store will be dialled out. To dial from the repertory memory while in the locked
state the redial key is pressed once followed by the number (0-9) of the store to be
dialled.
