Features
鈥?Full microprocessor control contributes to production
line rationalization, improved performance, improved
reliability, and design standardization.
鈥?Optimal reception system: Tuner functions are
controlled optimally by using a control
microprocessor.
鈥?Automatic adjustment system: Mechanical
adjustments eliminated by system developed in
conjunction with the control microprocessor
(LC72350). Variations due to the IC and the external
components are held to 30% of previous levels.
鈥?Temperature guarantee system: By providing a
temperature information output from the tuner chip
itself and by using the arithmetic functions in the
control microprocessor, this system provides
temperature correction, a function that was
previously difficult to implement.
鈥?Self-diagnosis system: Displays the failure mode.
