The key switch may be actuated into a plurality of switch positions by an independent key and the keypad may be used to input data into the processor. The processor, which processes data from external inputs and the keypad, includes a programmable memory selectively accessible by password. A first level of the processor is accessible without actuating the key switch from a first switch position or entering a password into the keypad. A second level of the processor is accessible by actuating the key switch into a second switch position. A third level of the processor is accessible by actuating the key switch into the second switch position and inputting a password to the processor through the keypad.
