Quick Front-panel Setup
RGB or Component out
Click the
SETUP
button, use
Up
or
Down
to HD Output menu, use
Left
or
Right
keys to choose input, press SELECT to choose. HDMI is always active.
HD Resolution
Go to the next menu down, and cycle through the list of resolutions. Press
SELECT
to choose. Note that our
Component port supports
1080p
– we’ve
found a number of TVs that support that resolution.
Air or Cable Tuning
Go to the next menu and select CATV, Air, IRC, HRC, or CATV Auto. Press
SELECT
to choose. IRC has the same channel map as standard CATV, except
for 5 and 6. The HRC channel map uses completely different frequencies than
the others. CABLE AUTO looks at the first few channels to determine the right
format. If there are no channels between 2 and 6, you may have to set the
tuning mode manually.
Select Scan Mode
Page down a number of menus to the
Scan Mode
menu. The
Left
or Right
keys will select several options
Digital (standard full scan)
Digital – Delete Analog (scan for digital, delete any analog channels)
Digital – Keep Analog (scan for digital, but keep all analog channels)
Analog – Delete Digital (scan for analog, delete any digital channels)
Analog – Keep Digital (scan for analog, but keep all digital channels)
Once you do the next step, scan from the front-panel menu, the tuner will
always scan this way from the panel or on-screen menu – until you change the
mode later on.
Channel Scan
The next menu starts the
Channel Scan
, just press
SELECT
to start scanning.
You can watch the scan progress from a pop-up window on the video outputs
from the tuner. You can watch the scan process if the output of the tuner is fed
to a display. A Cable analog/digital scan will take 7 minutes, only digital 6
minutes (the analog scan is faster).
