•Some cable TV companies offer “premium pay channels”. Since the signals of these premium pay channels are scrambled, a cable TV converter/descrambler is generally provided to the subscriber by the cable TV company. This converter/descrambler is necessary for normal viewing of the scrambled channels. (Set your TV to channel 3 or 4, typically one of these channels is used. If this is unknown, consult your cable TV company.) For more specific instructions on installing cable TV, consult your cable TV company. One possible method of utilizing the converter/descrambler provided by your cable TV company is explained below.
Please note: An RF switch provided with two inputs (A and B) is required (not supplied).
“A” position on the RF switch (not supplied): You can view all unscrambled channels by using the TV’s channel keys. “B” position on the RF switch (not supplied): You can view the scrambled channels via the converter/descrambler by
