Stereo RF Modulator  
15-2525  
OWNER’S MANUAL —  
Please read before using this equipment.  
Thank you for purchasing a RadioShack Stereo RF  
Modulator. Your modulator is designed to convert the  
separate audio and video signals from a video camera,  
computer, portable VCR, DVD player or satellite receiver  
into VHF TV signals that you can view on a TV set  
without Audio/Video (A/V) inputs. This means you can  
connect a DVD player to an older TV's antenna/cable  
input. The modulator's gold-plated jacks and terminals  
assure maximum reliability and minimum signal loss.  
The modulator has two sets of inputs (front/back) so you  
can connect two devices at the same time.

CONNECTIONS  
USING YOUR MODULATOR  
Use the push-button switch on the front panel to select the  
device connected to the front or the back of the  
modulator. The FRONT LED lights green when  
the front jacks are selected.  
Connection Notes  
If your TV only has 300-ohm VHF screw terminals, attach a 75- ohm to 300-ohm matching transformer to  
the screw terminals and connect the coaxial cable to the transformer to complete the connection.  
Your modulator has two sets of inputs, one in the back and one in the  
front. The following connection information applies to either set of inputs.
