User Manual
Introduction: Congratulations on your purchase of Sima’s RF Signal
Modulator (Model SRF). This unit will enable any VHF television set to
receive signals from all A/V video equipment such as DVD players, video
game systems, satellite receivers, camcorders and more. The RF Signal
Modulator converts the separate Audio and Video input signals into
normal VHF signals for television. The unit has a built-in automatically
switched antenna/cable input. It also has a built-in Auto Switching feature
that re-routes the external in and out sources to the TV set when a video
signal is not detected.
This package includes: 1 RF signal modulator
1 AC to DC power adapter (12V DC, 150 ma)
1 user manual (this document).
FCC Conformity: This device complies with Part 15 Rules of the Federal
Communications Commission. Operation of the SFR RF Modulator is
subject to the following two conditions. 1. This device may not cause
harmful interference. 2. This device must accept interference received,
including interference that may cause undesired operation

Connection: You will need one A/V cable with RCA style jacks and
two 75 Ohm coaxial cables with F-type connectors (not included) to
connect it between a video input source and your TV set.
Steps:
1. Connect a pair of RCA-style cables from the “Audio out” jacks on your A/V
equipment (DVD, video game, satellite receiver) to the “Audio In” jacks of the
RF modulator.
2. Connect an RCA-style cable from the “Video out” jack on your A/V equipment
(DVD, video game, satellite receiver) to the “Video In” jack of the RF
modulator.
3. Connect the coaxial cable with your VHF signal (TV antenna/cable) to the 75
Ohm coaxial “ANT IN” input on the RF modulator.
4. Using another 75 Ohm coaxial cable connect the “TO TV” terminal on the RF
modulator to the cable or VHF/UHF input on your television set. Note: If your
TV set does not have a VHF 75 Ohm connector, you will also need a 75Ohm
to 300 Ohm matching transformer.
5. Plug the AC/DC adaptor into a standard 120V AC outlet and plug into RF
Modulator
6. Move the switch on the back of the RF Modulator to the channel (3 or 4) you
want to use for the A/V signal.
7. Turn on A/V equipment. The signal is sent automatically sent to the TV.
8. Turn off A/V equipment to view antenna/cable programs.
9. Change the “ohms” switch on the RF Modulator to the position that gives you
the best picture quality, typically 75 ohms.
