LCD display — The LCD displays the horizontal and vertical scanning rates of the input

signal, and indicates the horizontal and vertical centering status and limits.

LCD screen backlight

The LCD lights for 15 seconds at power-up and it remains lit as long as an input signal is
present at the selected input. To force the backlight to remain off at all times except at
power-up, set

DIP switch 8

(No Backlight) to On (up) (see

Rear Panel DIP Switches

on

page 8).

Scan rate indication

When the interface is powered on, the LCD lights for 15 seconds while it determines
whether an input sync signal is present. If

DIP switch 8

is set to On (up), the LCD lights

for three seconds only (see

Rear Panel DIP Switches

on page 8).

If the interface does not detect an input sync signal, the LCD goes dark and displays

No Signal

until the interface receives an active sync signal.

z

If the interface detects an input sync signal, the LCD displays the horizontal and
vertical scan rates (sync frequencies) in the following format:

Hxxx.xxk
Vxxx.xHz

The first line shows the horizontal rate in kiloHertz; the second line shows the
vertical rate in Hertz.

Centering indications

While the vertical (

{

) or horizontal (

[

) centering (shift) controls are being adjusted, the LCD

displays

H-Shift

or

V-Shift

. That message remains on the LCD (in place of the scan rates)

until the centering control has been inactive for 3 seconds. When a centering control reaches
its minimum or maximum limit, the LCD displays

Min

or

Ma

x on the line below H-Shift or

V-Shift.
Once the centering controls are no longer active, the centering settings are saved, and the
LCD displays the current scan rates.
If

DIP switch 1

(DDSP) on the rear panel is set to On (up, see

Rear Panel DIP Switches

on

page 8) and a centering control is rotated, the LCD displays

N/A DDSP On

, and the image
