Abstract
Output power of a laser beam emitted by a laser in an electro-optical reader is regulated by storing a killswitch byte in non-volatile memory, and by checking whether the killswitch byte is in a default state or a kill state prior to performing reading. A controller detects a fault condition and responsively changes the killswitch byte to the kill state, in order to permanently deenergize the laser and to maintain the laser permanently deenergized after the killswitch byte has been changed to the kill state.
