INSTALLATION INSTRUCTIONS
I. Frequency Band Selection (UHF or CATV ULTRA channel)
1. Set the UHF/ULTRA switch to UHF for UHF channel band or ULTRA for CATV channel band.
2. Plug in DC power plug to the HMM-3 Power jack.
The Band Indicator located at left of front panel, will be lit for UHF selection only.
The indicator will be off for ULTRA CATV selection.

3. Repeat step 1.& 2. for input of B and C for channel selection.
III . How to use modulator
1. Connect a yellow color cable between HMM-3 AVA video input and your video device source and connect
2-wire stereo dubbing cable between HMM-3 AVA audio phone input and your video source, For
AVB/AVC connection, to follow same procedure as AVA .
Note : Three dubbing cables are included in the HMM-3 for audio connection along with three video cables
for video connection.
2. Connect RF OUT to the UHF/CATV input of the TV set or cable set-top converter.
3. Plug the provided Power Supply into the power line and HMM-3 power jack.
4. For channel selection, it is required that a channel be skipped between the channel A,B and C modulator
outputs. This is to avoid co-channel interference. For example, if the channel A output is chosen as
channel 23, then to avoid co-channel interference channels B and C should not be chosen as channel 22
or 24.

IV. Picture Brightness
To adjust for proper brightness, turn the corresponding trimpot on the bottom of the HMM-3.
See picture below.
V . Video Looping
The HMM3 is capable of outputting a quality picture of adequate brightness even when the video input has
been looped to the baseband video inputs of a TV or VCR.
Steps for adding video looping to the HMM-3 video input
1. Connect a RCA-Y plug (not included) to the selected video input of HMM-3 (A,B,C)
2. Connect a RCA cable from the “Video Output” of the video source (TV, VCR, DVD player etc.) to the
RCA-Y that is connected to the HMM-3.
3. Connect another RCA cable from the RCA-Y plug on the HMM-3 to the “Video Input” of the unit being
looped to (TV or VCR).
4. Check the picture from the HMM-3 on the selected channel (A,B,C). If the picture is too dark, then
adjust the picture brightness by using the video adjustment trimpot on the bottom of the unit. Adjust
the video level to a comfortable brightness as compared to a typical off-air signal
VI . Audio Looping
Audio looping can be done in a similar manner as the video looping.
1. Connect a RCA Y-plug (not included) to the selected audio input on the HMM-3.
2. Connect a RCA cable from the “Audio Output” of the audio source (TV, VCR, DVD player etc.) to the
RCA-Y that is connected to the HMM-3.
3. Connect another RCA cable from the RCA-Y plug on the HMM-3 to the “Audio Input” of the unit being
looped to (TV or VCR).
