• LCDs can be driven directly. This includes time display, music calendar, remaining tunes and other display
functions.
• NEC format remote control input possible; index serch, direct tune selection through keypad and other
functions can be added.
• Supports auxiliary functions including synchronization input, double-speed output and pitch control.
• Easy switching between deck and portable equipment using external pins.
(i) With deck type selected, performs tray loading function.
(ii) With portable type selected, displays detection of weak battery and executes emergency termination
when battery voltage is low.
In this way, it functions specific to the system required.
• A built-in test mode facilitates adjustment of the CD player and can be used for tests and evaluations.
