When do we need to disable Power key?

To prevent keypad from being powered off accidentally. This feature is useful because the following two beep keypad functions will not work if keypad is powered-off: 1．During the meeting, when you want to use the “Beep Keypads Ranged” feature to warn audience when the keypad is out of base station coverage range. 2．After the meeting when you want to use the “Beep Keypads” feature to locate the missing keypad.
