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. If a password is configured on the

phone, you must enter the password after pressing **#.

Make sure to lock options after you have made your changes.

Caution Do not press **# to unlock options and then immediately press **# again to lock

options. The phone will interpret this sequence as **#**, which will reset the

phone. To lock options after unlocking them, wait at least 10 seconds before you

press **# again.
