Abstract
A mobile data terminal system is capable of voice or microprocessor controlled data transmission over a keyed transmitter. The improved timer apparatus disables further transmission if the transmission duration or the average duty cycle over a predetermined time period of repeated transmitter keying exceed predetermined limits. Where the disable mode resulted from a microprocessor fault, the transmitter continues to be disabled until the microprocessor is reset.
