****Miscoe Hill School Only**** The helpdesk has been asked frequently about classroom telephones locking. This is a feature built into the phone so you may clean the buttons without dialing Switzerland in the process. To lock the keypad, press and hold the star Key (*) until the LCD shows “Keypad Locked”. To unlock the keypad repeat the process. It will ask you for a password to unlock the phone. By default there is no password. Just select OK.
When your computer has a black screen and you can't see control alt delete, hold the power button in for 7 seconds to power off the computer. Power it back on.
