Safety First
Please review the following safety precautions. If this is first time to use a terrestrial TV receiver, then read this
manual before installing or using the terrestrial TV receiver. If the receiver is not functioning properly, please
contact ViewSonic customer support.
The lightening symbol in a triangle is used to alert you to the presence of dangerous voltage inside the receiver that
may be sufficient to constitute a risk of electric shock to anyone opening the case. It is also used to indicate improper
installation or handling of the receiver that could damage the electrical system in the receiver or in other equipment
attached to the receiver.
The exclamation point in a triangle is used to alert you to important operating and maintenance instructions.
Failure to follow these instructions could result in injury to you or damage to the receiver.
Be careful with electricity:
 Power outlet: To prevent electric shock be sure the electrical plug used on the receiver’s power cord matches
the electrical outlet used to supply power to the receiver. Connect the power cord only to a power
source that operates at 90~260 Volts AC, 50/60 Hz.
 Power plug: If a three-prong power plug is provided with the receiver, be sure it is used with a properly
grounded three-wire power socket.
 Power cord: Be sure the power cord is routed so that it will not be stepped on or pinched by heavy items.
 Power overloading: Avoid overloading electrical outlets or extension cords, which otherwise could result in
electric shock or fire.
 Lightening: For protection from lightening, or when the receiver is left unattended for a long period,
disconnect it from the power source.
 Protect other equipment: Unplug the receiver before connecting any other equipment, especially the TV
antenna Connect all equipment to the receiver before plugging any power cords to
the power source.
 Power line: Be sure your TV antenna is not located near overhead power lines, or where it might fall into
any power lines. Also be careful to avoid touching any such power lines when installing the
TV antenna.
 Antenna Grounding: Be sure that antenna is grounded to provide protection from Lightening and build-up
of static electricity.
 Antenna Installation Instruction:
1. Outdoor Antenna Grounding:
If an outside antenna or cable system is concerned 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, connection to
grounding electrodes, and requirements for the grounding electrodes.
2. 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.
3. Power Lines:
An outside antenna system should not be located in the vicinity of overhead power lines
or other electronic light or power circuits, or where it can fall into such power lines or
circuits. When installing an outside antenna system, extreme care should be taken to
keep from touching such power lines or circuits as contract with them might be fatal.
Also follow these precautions:
 Ventilation: Do not block the ventilation slots on the receiver, or place any heavy object on top of it.
Blocking the air flow could damage the receiver. Arrange components so that air can flow freely around the
receiver. Ensure that there is adequate ventilation if the receiver is placed in a stand. Put the receiver in a
properly ventilated area, away from direct sunlight or any source of heat.
 Overheating: Avoid stacking the receiver on top of a hot component such as a power amplifier.
 Risk of Fire: Do not place the receiver on top of any easily combustible material, such as carpet or fabric.
 Proper Connections: Be sure all equipment cables are connected to the receiver as described in this manual.
 Object Entry: To avoid electric shock, never stick anything in the slots on the case or remove the cover.
 Water Exposure: To reduce the risk of fire or electric shock, do not expose the receiver to rain or moisture.

HD12 Physical Installation
There are many ways to connect the HD12 Receiver to your home entertainment system, depending on
the equipment and connection types you have. However, for the best video/audio quality, use the higher
quality Y/Pr/Pr or DVI connections if available. And always remember to disconnect the receiver from the
power source prior to connecting or after disconnecting the cable to the UHF/VHF antenna.
Before Connecting to other devices
When the receiver is connected to the antenna attached with a signal amplifier which requires
power supply, be sure the amplifier doesn't have power leakage before connecting the coaxial
cable to the receiver.
Connecting Antennas
1. Connect Antenna to the Receiver RF Input by using a coaxial RF cable.
2. You may connect Cable NTSC signal to the receiver by using a coaxial RF cable.
Note: except the terrestrial ATSC signal, the Receiver
also could receive the traditional NTSC signal, please note
that it could not recognize the digital cable QAM signal to
decode.
