• See page 35 for Waveforms. • See page 50 for IC Block Diagrams. • See page 54 for IC Pin Function Description.
Note 1:
When the KEY board is defective,
replace the complete mounted board.
Note 3:
IC102 and IC104 on the MAIN board cannot replace with single.
When these parts are damaged, replace the complete mounted board.
Note 2:
When the RF modulator (Ref .No. RF1) is replaced, refer to “NOTES ON THE WIRELESS
