Power on
HV-120 can support 2/3/4/ 5/6/7/8 MHz bandwidth DVB-T signal automatically, and there no need to
set bandwidth mode switch as HV-110.
Apply DC 12Vto the power jack.
Connect RF-in and the display output
Feed the RF-in to the right SMA connector.
There are two antenna ports, one is for standard TV RF input (170~950MHz).
The other is for 1.2GHz or 2.4GHz RF input.
HV-120-1.2G supports both TV VHF/UHF and 1.2GHz band reception.
HV-120-2.4G supports both TV VHF/UHF and 2.4GHz band reception.
Active antenna (12V power) is also supported, but you need to install a jumper on the board and
enable it in the menu. More details described later.
Both HDMI and CVBS output are supported simultaneously, but the mechanical design allows only
one to be connected.

A. The default PID’s (video: 0x641, audio: 0x642) are set to the same as HV-10x and HV-20x.
(and HV-310 with firmware 0.0.2.4.56 or later)
B. In “Manual Input”mode, PAP/PMT mismatch handling mechanism is disabled.
(Hint: While a service/program is tuned and played well, you may click on “Yellow”button to
learn the signal statistics and the PID’s of current service/program.)
Channel PAT Changed
When the source video of the channel is changed and if the PAT version code is different from the
previous one, you may need to do channel scan again. Typical example is that the transmitter is
changed from HV-100 to DC-101 or any other Tx devices.
If you start to play TV, and the following message pop up, please click on “OK”to do channel scan.
(PAT is short for Program Association Table in a video transport stream.)

When signal statistics OSD is enabled, there might be snow noise sometimes, with HD service and HDMI
display output specifically.
The problem is caused by the bottleneck of DDR memory access. You may minimize this problem by
lowering display memory access.
In Menu-> Settings-> Display Preference, please set the display mode to1080P30 or 1080P25 if the service
is 1080P, and set to720P30 or 720P25 if the service is 720P.
