For Subscribers to Unscrambled Basic Cable TV Service with Scrambled
Premium Channels
If you subscribe to a cable TV service in which basic channels are unscrambled and premium channels require
the use of a Converter/Descrambler box, you may wish to use a signal Splitter and an A/B Switch box (available
from the Cable company or an electronics supply store). Follow the connections shown below. With the switch
in the “B” position, you can directly tune any nonscrambled channels on your unit. With the switch in the “A”
position, tune your unit to the output of the Converter/Descrambler box (usually channel 3 or 4) and use the
Converter/Descrambler box to tune scrambled channels.

This unit has an extended tuning range and can tune most cable channels without using a Cable TV Converter
box. Some cable companies offer “premium pay channels” in which the signal is scrambled. Descrambling
these signals for normal viewing requires the use of a descrambler device which is generally provided by the
cable company.
