7. REMOTE CONTROL
The µPD6121G IC is used for sending a remote-controller signal. This IC uses a custom code, which must be set
correctly to enable the control of the µPD178016GC-051 using a remote-controller signal.
The µPD178016GC-051 is operated with custom code 8604H. To set this code, connect diodes and pull-up
resistors on the key matrix of the transmitter IC (µPD6121G). (See Section 7.4.)
