DECLARATION OF CONFORMITY
THIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES. OPERATION IS
SUBJECT TO THE FOLLOWING TWO CONDITIONS: (1) THIS DEVICE MAY NOT CAUSE
HARMFUL INTERFERENCE, AND (2) THIS DEVICE MUST ACCEPT ANY INTERFERENCE
RECEIVED, INCLUDING INTERFERENCE THAT MAY CAUSE UNDESIRED OPERATION.
Installation requirements:
FCC classifies this product under part 15 of its rules as a “television interface device”.
Systems designed using television interface devices have the following legal requirements:
1) The modulated channel signal strength may not exceed 15.56dBmV at any television.
Federal Regulation 47CFR15.115(b)(1)(i).
2) If an antenna is used in the system, the modulated channel signal strength may not exceed
-51dBmV at the antenna input port.
For the Installer:
The system you design must comply with these regulations. As the installer, you are
responsible. The easiest way to be fully compliant is to use a ChannelPlus coax panel.
ChannelPlus panels have the necessary isolation from the modulator input ports to the
antenna input port and gain characteristic from the modulator input ports to the television
output ports. These features will make your modulator comply with the above requirements.
The shown is fully compliant.

14) Protective Attachment Plug - The product is equipped with an attachment plug having
overload protection. This is a safety feature. See Instruction Manual for replacement
or resetting of protective device. If replacement of the plug is required, be sure the
service technician has used a replacement-plug specified by the manufacturer that
has the same overload protection as the original plug.
15) Outdoors Antenna Grounding - If an outside antenna or cable system is connected to
the product, be sure the antenna or cable system is grounded so as to provide some
protection against voltage surges and built-up static charges. Article 810 of the
National Electrical Code, ANSI/NFPA 70, provides information with regard to 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. See figure A.
16) Lightning - For added protection for this product during a lightning storm, or when it is
left unattended and unused for long periods of time, unplug it from the wall outlet and
disconnect the antenna or cable system. This will prevent damage to the product due
to lightning and power-line surges.
17) Power Lines -An outside antenna system should not be located in the vicinity of
overhead power lines or other electric light or power circuits, or where it can fall into
such power lines or circuits. When installing an outside antenna system, extreme care

Things to watch for:
No picture
signal. Check that the TV and the modulator are tuned to the same channel.
For example, if the modulator is broadcasting on UHF channel 16, make
sure the TV is on UHF 16 rather than CATV 16. UHF 16 and CATV 16 are at
different frequencies.
Weak ChannelPlus UHF channel
be sure thatit is connected.
LEDs blink
channels. The display will blink if you have made an ‘illegal’ choice. See
the section onprogramming.
Herringbone interference on ChannelPlus channel (diagonal lines)
You may have chosen a channel number that is not completely vacant.
Distant UHF stations may be un-watchable, but will cause interference if
you try to create a new channel at the same frequency. Also, cable
companies often have extra signals where there should be none. Try
moving the ChannelPlus channel to another number. You may have to add
a low passfilter to removecable company noise.
Herringbone interference on many channels (disappears when you
remove the modulator)
can overdrive many RF amplifiers. Reduce the RF output using an
attenuator. (ChannelPlus coax panels are designed to take the full output
of these modulators.)
Audio volume is low
monaural. For proper audio level, both right and left inputs must be used. If
you have a mono source, connect it to both right and left inputs using an
RCA ‘Y’ connector.
No color on ChannelPlus channels … You may have chosen the
incorrect cable standard. Not all televisions can accommodate the
1.25MHz frequency difference between the H and I cable standards.

Changing modulation standards
Cable HRC andIRC considerations
Most cable services use IRC frequency assignments. This is the default for
the ChannelPlus modulators. However, if the cable service
uses HRC or the TV appears to search for the "house channels," the
modulator can be reprogrammed to use HRC assignments by entering the
number “ 98”. Set to IRC by entering a “99”. Both of these settings are only
used for setting HRC/IRC. : This setting can be entered on any
modulator channel, A, B, C, or D, and affects all channel assignments for
that unit. Cable channels must eitherbe IRC or HRC.
