181-CHANNEL REMO TE CONTROL
CABLE CONVERTER
with Volume Control
INTRODUCTION
Your RadioShack 181-Channel Remote Control Cable Converter lets you
connect a non-cable-ready video
product to cable. It is compatible with
all cable systems and gives you complete remote control selection of all
cable channels (VHF, Mid-Band, Super-Band, and Hyper-Band) . The converter’s volum e control let s you adju st
a connected TV’s sound. You can also
use the converter’s remote control to
turn on or off and fine tune most TVs.
Important Note:
This cable conver ter
does not decode “scrambled” premium channels. You can, however , use
it with the cable box provided by the
cable company so you can receive
premium channels and still have remote control of all other channels.
Note to Cable TV System Installer:
This reminder is provided to call the
CATV system installer’s attention to
Article 820-40 of the NEC that provides guidelines for prope r grounding
and, in particular, specifies that the
cable ground be connected to the
grounding system of the building as
close to cable entry as practical.
Note:
You need two AAA batteries
and a 75-ohm coaxial cable to operate
your converter. You might also need
extra coaxial cable, an A/B switch, a
two-way splitter, and (if your TV has
only 300-ohm terminals) a 75-to-300
ohm transformer. Read the entire
“Connecting the Conver ter” section of
this Owner’s Manua l before you be gin
to install your converter.

Your converter’s remote control requires two AAA batteries (not supplied) for power. For the best
performance and l ongest life, we recommend RadioShack alkaline batteries.
Cautions:
• Use only fresh batteries of the
required size and recommended
type.
• Do not mix old and new batteri es,
different types of batteries (standard, alkaline, or rechargeable), or
rechargeable batteries of different
capacities.
Follow these steps to install batteries.
Warning:
promptly and properly . Do not burn or
bury them.
Caution:

If the cable system in you r area is not
standard, use a paper clip or other

Note:
HRC and IRC are methods
used by some cable companies for

all channels on HRC systems are
slightly different frequencies from
those used on standard systems.
