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.

We recommend you reco rd your converter’s serial numbe r here. The number is on the bottom of the 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:

CHOOSING THE CABLE
SYSTEM TYPE
There are three types of cable TV
channel frequency systems: standard, IRC, and HRC. Most cabl e systems use a standard system. Your
converter is pres et to use a standard
channel frequency system.

If the cable system in you r area is not
standard, use a paper clip or other
pointed object to se t
the bottom of the converter for the
type of cable system you have.
Note:
HRC and IRC are methods
used by some cable companies for
converting satellite and local broadcast channels to cable channels.
Channels 5 and 6 on IRC systems and
all channels on HRC systems are
slightly different frequencies from
those used on standard systems.

VARIATIONS IN
CHANNEL NUMBERING
Some cable compan ies us e a ch annel
numbering system that is different
from the one used by your converter .
For example, the channel your cable
company calls 21 might ap pear as
on the converter’s display.
Use the supplied cha nnel number labels to mark the cable company’s
channel numbers that differ from the
channels on the converter’s display.
Then peel off the bac king on each label and paste the large label on the
converter and the smal l label on your
remote control.
This table compares channels that
your converter shows to channel numbers that might be assigned by your
local cable company.

Your RadioShack 181-Cha nnel Remote Control Cable Converter is an example
of superior design and craftsmanship. The following suggestions will help you
care for your converter so you can enjoy it for years.
Keep the converter dr y. If it gets wet, wipe i t dry i mmedia tely. Liqui ds
might contain minerals that can corrode the electronic circuits.
Use and store the converter only in normal temperature environments. Temperature extremes can shorten the life of electronic devices, damage batteries, and distort or melt plastic parts.
Keep the converter away from dust and dirt, which can caus e premature wear of parts.
Handle the converter gently and carefully. Dropping it can damage
circuit boards and cases and can cause the converter to work improperly.
Use only fresh bat teries of the required s ize and recomme nded type .
Batteries can leak chemical s that damage you r converter’ s electron ic
parts.
Wipe the converter with a damp cloth occasional ly to keep it looking
new. Do not use har sh chemic als, cle aning so lvents, or strong de tergents to clean the converter.
Modifying or tampering with the converter’s internal components can cause a
malfunction and mi ght invalida te its war ranty and vo id your FCC a uthorizati on to
operate it. If your converter is not performing as it should, take it to your local RadioShack store for assistance.

THE FCC WANTS YOU TO KNOW
Your converter might cause TV or radio interference even when it is operating
properly. To determin e whether your conv erter is c ausing th e interfere nce, turn o ff
your converter. If the interference goes aw ay, your converter is caus ing it. Try to
eliminate the interference by:
• moving your converter away from the receiver
• connecting your converter to an outlet that is on a different electrical circuit from
the receiver
• contacting your local RadioShack store for help
If you cannot eliminat e the in terferen ce, the FCC requ ires that y ou stop us ing y our
converter.
