OPERATIONS

NoteIn the step 3, if two or more program sources are selected atthe same time (by using input selectors), be sure to rememberthe priority order of the input sources.Priority order of audio sources: 1) TAPE 1, 2) VCR/TAPE 2,3) LD/TV, TUNER, CD or PHONO.Priority order of video sources: 1) VCR/TAPE 2 , 2) LD/TV. If you select LD/TV, TUNER, CD or PHONO, be sure that

TAPE 1 and/or VCR/TAPE 2 are not being selected. If you select TAPE 1 and VCR/TAPE 2, and another input

selector at the same time, the result will be the visual ofVCR/TAPE 2 and the sound from TAPE 1.

If you select both LD/TV and TAPE 1 at the same time, theresult will be the visual of LD/TV and the sound from TAPE1.

Once you play the LD player, its visual will not be interruptedeven if other input selectors except VCR/TAPE 2 areselected.
