If none of the preceding hookups work, check with your cable company.
You may need to purchase a video switching system from your local
electronics or video retailer. This will easily handle most hookup problems.
Remote Control of the Cable Converter
If you have a cable converter, you will probably want to program your
VCR's remote control so you can easily change channels. The process is
the same as for programming the remote to operate your TV. For
additional details, see page 36.
Hold down the CATV button and press the number of your brand of
cable box (shown in the chart).
If that button combination does not work, or if your brand is not on the
chart, just go through all the button combinations until you find the one
that works best.
