Your modulator provides four sets of input
jacks that can be used to connect up to four
home entertainment components, and each
set of the input jacks includes one
jack. It can auto-select the video signals if
both S-video and composite signals are
received. S-video signals have the highest
priority.
Connect your antenna or the cable TV's
output to
on the back of the modulator
ANT IN
with a 75Ω (75-ohm)
F-connector coaxial cable.
Plug the connector on one end of a
75Ω F-connector cable to
TO TV
of the modulator, and plug the connector on
the cable's other end to your TV input
terminal.
Plug the connectors on one end of a stereo
A/V cable into one set of the

jacks on the modulator. Plug
INPUT
the connectors on the cable's other end into
the video and audio output jacks on the
component. Or, you can connect an S-video
cable from the S-VIDEO output of a device to
an
jack on the modulator in

You can power the modulator using the
supplied 9V, 100 mA AC/DC adapter.
."%#76+10".
• You must use a Class 2 power source that
supplies 9V DC and delivers at least 100
mA. Its center tip must be set to positive and
its plug must fit the modulator's DC 9V jack.
The supplied adapter meets these
specifications. Using an adapter that does
not meet these specifications could damage
the modulator or the adapter.
• If you do not plan to use the modulator for a
week or more, unplug the adapter from the
AC outlet.
Always connect the AC adapter to the
modulator before you connect it to AC power.
When you finish, disconnect the adapter from
2
AC power before you disconnect it from the
modulator.
When your connections are complete, insert
the supplied AC adapter's barrel plug into the
S-VIDEO
jack on the back of the modulator, then
DC 9V
plug the adapter into a standard AC outlet.

determined by turning the equipment off and on,
the user is encouraged to try to correct the
interference by one or more of the following
measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the
equipment and receiver.
• Connect the equipment into an outlet on a
circuit different from that to which the receiver
is connected.
• Consult your local RadioShack store or an
experienced radio/TV technician for help.
• If you cannot eliminate the interference, the
FCC requires that you stop using your

modulator.
Changes or modifications not expressly approved
by RadioShack may cause interference and void
the user's authority to operate the equipment.
This device complies with Part 15 of the FCC
Rules. Operation is subject to the condition that
this device does not cause harmful interference.
This device complies with Part 15 of the FCC

Keep the modulator dry. If it gets wet, wipe it dry
immediately. Use and store the modulator only in
normal temperature environments. Handle the
modulator carefully; do not drop it. Keep the
modulator away from dust and dirt, and wipe it with
a damp cloth occasionally to keep it looking new.
If your modulator is not performing as it should,
take it to your local RadioShack store for
assistance. Modifying or tampering with the
modulator's internal components can cause a
malfunction and might invalidate its warranty and
void your FCC authorization to operate it.
