Safety Instructions & Precautions
CA UT ION
RISK OF ELECTRIC SHOCK
DO NOT OPEN
!
CAUTION: TO REDUCE THE RISK OF ELECTRICAL SHOCK,
DO NOT REMOVE COVER FROM THIS UNIT.
NO USER-SERVICEABLE PARTS INSIDE.
REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
WARNING: TO PREVENT SHOCK HAZARD,
DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE.
Do not operate the HD modulator in high-humidity areas or expose it to water or moisture. Objects
filled with liquid should be placed on the device.
Disconnect the product from the wall outlet prior to cleaning. Use a light, damp cloth (no solvents) to
dust or clean the product.
Do not block or cover slots and openings in the HD modulator. These are provided for ventilation and
protection from overheating. Never place the HD modulator near or over a radiator or heat register.
Do not place the HD modulator in an enclosure such as a cabinet without proper ventilation.
We strongly recommend using the enclosed ground wire connecting to the ground cable of your
house/building to avoid voltage spikes or ground fault.
Never insert objects of any kind into the HD modulator through openings, as the objects may touch
dangerous voltage points or short out parts. This also could cause fire or electrical shock.
When replacement parts are required, ensure that the service technician uses replacement parts
specified by the manufacturer. Unauthorized substitutions may damage the HD modulator or cause
electrical shock or fire and will void the warranty.
Upon completion of any service or repair to the HD modulator, ask the service technician to perform
safety checks to ensure that the HD modulator is in proper operating condition.

Troubleshooting
3. No picture or channel found at TV
Verify the HDTV has a QAM (digital cable) tuner.
4. Image Breakup
SOL. Video break up is often caused by an issue in
1. Vertical lines in picture with motion ANS: change Video source to 720P or 1080P
2. Unable to find modulated channel ANS: Confirm CABLE or Antenna is set on TV
ANS: Scan TV channels
ANS: Confirm CW Signal is disabled
Verify that you have performed a full channel scan
on the HDTV with “cable mode” selected. Lower the
power on the unit, then verify that the modulator is
not conflicting with any other channel by
connecting the unit directly to the HDTV.
the RF signal. You may have chosen a channel
number that is not open or has a signal from
another product.
SOL. If you are combining with other modulators, be
sure the channel number selected on the modulator
does not conflict with any other channels, keep in
mind that some analog modulators may need 2
channel spacing causing interference.
SOL. If you are combining with a cable service, keep
in mind that they sometimes have extra signals that
a TV will not display and can cause interference.
SOL. There may also be an RF power balance issue.
Verify that the RF power of the unit is balanced with
signals from other modulators and from the cable
company. As a test, try removing all other signals
(cable, other modulators, etc) and see if you still see
similar issues.
SOL. Some TVs will also show video issues if the
signal strength is too high. Try lowering the RF
power on the unit to ensure you are not overdriving
the HDTV tuner.
BEST Practices:
Outdoor Antenna Grounding - If you connect an outside antenna or cable system to the product, be sure the
antenna or cable system is grounded to provide protection against voltage surges and built-up static charges.
Refer to Section 810 of the National Electrical Code, ANSI/NFPA No. 70, for proper grounding of the mast and
supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors,
location of antenna discharge unit, connection to grounding electrodes, and requirements for the grounding
electrode
