1.1 IMPORTANT SAFETY INSTRUCTIONS
Thank you for choosing our product. Before installation, we would like to re-
mind you some notes, which is very important for operating safely and prop-
erly, as follows:
• Be sure to read this user manual before starting your operation.
• When the unit is suddenly moved to a hot area from a cold area, it may
cause some problems. In that case, turn o the power, and turn on again
after 1-2 hours.
• Keep modulator placed in clean space with sucient ventilation.
• Do not cover the modulator with or place it on a unit that emits heat.
• Clean the case by a soft cloth with a little washing liquid.
• Do not remove the cover.
• Do not let the unit exposed to extreme heat, cold or humid conditions.
• No liquids or any other materials to come inside of the unit.
1.2 GENERAL DESCRIPTION
The machine is a composite video input standard definition DVB-T single route
modulator which provides COFDM RF signal in range of 50-860MHz.
It consists of A/D, Coding, Modulation, Frequency conversion which provides
bandwidth of 6/7/8MHz to select.
It is designed to achieve CVBS and HD input, and it can also supports standard
H.264 encoding.
It is an excellent choice to transport video/audio signals from TV satellite re-
ceivers, surveillance camera or video/media players to a LCD TV or set-top-
box.
It can be used in series with other modulator so the number of channels in
the coaxial cable no the SMATV system can be increased as desired.

Note:
1.Since the modulator uses H.264 encoding, users need using DVB-T service which
supports standard H.264 encoding for normal display.
2.HD program which contains HDCP agreement protection will not play normally,
such as Blue-ray Disc and so on. Press RETURN 3 seconds in the boot interface can
resolve this problem.
3.If the image and sound are not synchronous, please insert HD port again, it will
return to normal.
