Unlocking and Locking Options
Configuration options that can be changed from a phone are locked by default to prevent users from
making changes that could affect the operation of a phone. You must unlock these options before you
can change them.
When options are inaccessible for modification, a locked padlock icon appears on the configuration
menus. When options are unlocked and accessible for modification, an unlocked padlock icon appears
on these menus.
To unlock or lock options, press **#. This action either locks or unlocks the options, depending on the
previous state.
Note If a Settings Menu password has been provisioned, SIP phones present an “Enter password” prompt after
you enter **#.
After you have made your changes, make sure to lock the options.
Caution Do not press **# to unlock options and then immediately press **# again to lock options. The phone
will interpret this sequence as **#**, which resets the phone. To lock options after unlocking them, wait
at least 10 seconds before you press **# again.
