We recommend switching the monitor off when it is not in use for a long time.
NOTE:
The monitor automatically goes through the Power Management System (PMS) steps
when it is idle. To activate the monitor, press any key on the keyboard or move the mouse.
Check the cable connections. Make sure all the cables are connected correctly. Including a
female F Type connector(ANT IN) for VHF/UHF antenna input, a female F Type(MD OUTPUT)
with user-selectable channel 3 or 4NTSC RF output to analog television receiver, female RCA
connectors for stereo left and right audio (white and red) and a female RCA connector for
composite video (yellow). Then insert the adapter whose output plug is into the STB’s DC
socket and the input plug is into the power socket. Put switch which is in the power socket on,
Turn on the television and switch to video mode.
Then Power System will work, and low voltage transformer will supply power to Control
System, ATSC Tuner and Modulator, and the LED Indicator state is red, meaning the STB
state is stand-by. When you turn the stand-by to power state by Remote Control or the press
button on the top of cover, then the LED Indicator state is green and STB is Power State. So
ATSC Tuner can receive VHF or UHF frequency signal and transfer it to low frequency signal,
then Demodulator demodulate the low frequency signal and output the Transfer Stream(TS) to
Decode System, Control System separate the program stream (PS) which come from Decode
System into Video PID and Audio PID, and then Audio Decoder and Video Decoder decode
them separately and output the digital video signal and analog signal is amplified by amplifier
and output to television. Also the digital video signal is converted to analog video signal by
NTSC Encoder and DAC and then output to television.
So you can see the picture and hear the sound in television with the program you select, If
there is no any program stored in the STB, or you want to add new program to program list,
you need to search program by Remote Control, the IR receiver receive the Infra-red which
come from Remote Control and encode it, Control System receive and deal the encoded
signal. If you have connected the STB to analog television receiver with RF cable, you also
can watch television, because the RF signal is modulate by Modulator and the RF output
channel is control by software, you can change it by Remote Control.
This STB provide the capability to automatically switch from Power state to the
Sleep(Stand-by) state after a period of time without user input, and the default period of
inactivity before the equipment automatically switches to the Sleep(Stand-by) state is four
hours. Also you can select the pre-set period of time or turn off this function by Remote Control
in Power sate.
