Wireless magnetic hand scanner 1 is coupled by a transceiver (not shown) to a terminal 2 which is part of a data collection system to which it is connected by cable 3. Hand scanner 1 includes signal lights 4, 5 and 6, as well as a buzzer contained within the housing. These signal lights and buzzer are employed to indicate the ready status of terminal 2 as well as operating conditions, such as completion of a valid scan of magnetic record 7. Control of the signal lights and buzzer is preferably accomplished by employment of a two-tone code comprising one tone selected from a group of four high tones and a second tone selected from a group of four low ones. These tones enable signaling of up to 16 conditions through the activation of various ones or combinations of the signal lights and buzzer.
