Abstract
A communication device including a power key located on an outer surface of the housing which may provide multiple functions, but is resistant to initiation of undesired handset functions. Control circuitry within the communication device may be configured to ignore any actuation of the power key with a duration less than a determined time period. The control circuitry performs a first function if the power key is depressed for a first duration, and performs a second function when the power key is depressed for a second duration. For example, depression of the power key for a short period of time may silence and incoming call alert, whereas depression of the power key for a longer period of time will turn the communication device on or off.
