 
Module security
If you purchased an optional analog module, you can 
protect it from unauthorized use by turning on module 
security. When module security is on, the phone 
requests the module code when you turn the phone 
on if (a) you have not changed the module code from 
the default of 12345, or (b) you have changed it 
and
it
differs from the security code. (See “Change module 
code” on page 87 for information about changing the 
module code.)
•
If you enter the correct code, the phone allows you to 
access analog module functions.
•
If you enter an incorrect code, you can’t access analog 
module functions.
•
If you choose
#6NLS, the phone ignores menu items that
pertain to the analog module and acts as if the analog 
module isn’t attached.
