Installing the TV
19
To use PIP with the Cable Box
❑
Turn on the cable box and VCR. Use the remote control’s TV/VIDEO
(yellow) button to set the PIP output to VIDEO 1. Change the PIP
channel via the cable box. (The cable box’s tuner is used as the
PIP video source; if you do not turn on the cable box, the PIP will
not work.)
✍
This system is needed because the cable box unscrambles only one channel at
a time (unlike regular cable, which makes all channels available concurrently).
