Unlocking the keypad

Here's how to temporarily unlock the keypad.
1. Press and hold the up and down buttons on the right
simultaneously for about five seconds.
2. The padlock icon will disappear. This means the keypad is unlocked
and can be used. The keypad will revert back to the locked state
after you've stopped pushing buttons for two minutes.
