Cable Tv Connections - Memorex MVDT2002BOM Owner's Manual

Cable TV connections

This unit has an extended tuning range and can tune most cable TV channels without using a cable
TV converter box. Some cable TV 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 TV company.

channel 3 or 4) and use the Converter/Descrambler box to select channels.

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 TV 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.
