2.2. Key lock

You have the option to protect your telephone from improper use by locking its keypad. I.e. with the telephone locked, no outgoing calls can be dialled. However, the telephone lock can be deactivated at any time.
To lock your Unify OpenStage telephone, press and hold the key for several seconds. The phone display will now show "Phone locked".
To unlock the phone please select "Unlock user?" and confirm with [OK]. Now enter your user name and confirm your entry with [OK]. The user password is comprised of:
"82 + extension VoiceMail PIN + 28". Example: 82123428.

Your phone is now unlocked.
