ENGLISH
This unit has an extended tuning range and can tune most cable 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.
FOR SUBSCRIBERS TO BASIC CABLE TV SERVICE
For basic cable service not requiring a Converter/Descrambler
box, connect the 75 ohm Coaxial Cable directly to the RF IN
Jack on the back of the unit.
FOR SUBSCRIBERS TO SCRAMBLED CABLE TV SERVICE
If you subscribe to a Cable TV service which requires the use of a Converter/Descrambler box, connect the
incoming 75 ohm Coaxial Cable to the Converter/Descrambler box. Using another 75 ohm Coaxial Cable, connect
the output jack of the Converter/Descrambler box to the RF IN Jack on the unit. Follow the connections shown
below. Set the unit to the output channel of the Converter/Descrambler box (usually 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.
