Abstract
A combination of automobile radio and city call or paging receiver equipped with a display (4) has the additional feature of a vehicle speed sensor (24) which is used to block display of possibly distracting information whenever the vehicle exceeds a predetermined speed limit set in a threshold switch (25). The display (4) is controlled by a microprocessor (7). A NAND gate (23), connected to the output of the speed threshold switch (25), is interposed between the city call data decoder (3) and the microprocessor (7). Another threshold stage (28) and NAND gate (27) can be interposed between the radio control panel (18) and the radio tuner (13) to keep the driver from making radio adjustments when he or she should be paying attention to the road instead.
