Additional Information
This feature allows you to lock your telephone’s
station assignment.
IMPORTANT NOTE: Under normal circum-
stances this setting should be left at the factory
default setting, which is NORMAL.
If your telephone is losing its station assignment,
and its display keeps reverting to “Station #??”,
this is due to interference on the line, and the
usual solution is to find the device causing the
interference and remove it from the system.
Some possible causes of interference are other
brands of multi-line phones, or equipment such
as security systems sharing the same line.
However, there are sources of interference that
are minor and infrequent, and that do not harm
the operation of the phones, yet could still cause
the phones to lose their station assignments. An
example of this sort of source of interference is
the X-10 home control products.
It is for cases such as this that the telephones
have the ability to lock the station assignments.
