prevents unauthorized or accidental adjustments to the
VSC 150’s settings via front panel controls by locking all
the front panel features except centering controls.
Adjustments can still be made via RS-232 control or
IR remote control when Executive mode is active. To
release Executive mode and allow access to all front panel
functions, press the Freeze and Size buttons simultaneously
again for 2 seconds.

Size control

— Press this button to activate the size

feature. When Size is active, the picture can be resized
vertically and/or horizontally by rotating the vertical and
horizontal Centering/Pan/Size rotary controls (13).
Observe the picture on screen as you adjust the controls.

screen’s limits. The Min/Max LED (14) lights red when the
minimum or maximum limit of a control has been reached.

The size feature affects both display outputs
simultaneously. The image is resized no matter what
format is selected (RGB, component, S-video or composite
video). The local monitor loop-out is not affected.

The size function remains active for 8 seconds after the
rotary controls become inactive. The rotary controls then

Power/signal lock LED

— If this indicator...

• Lights amber yellow without blinking, the VSC 150 is

receiving power, but no input signal is present.

• Blinks green, the unit is receiving power, but the input

signal has a resolution that is too low or too high.

• Blinks green when the signal is within range, the

VSC 150 is receiving commands from the IR 601
remote control.

• Lights green without blinking, the input signal is within

range, and the VSC 150 has locked to that particular
resolution.

IR receiver window

— The VSC 150 receives infrared

signals from the IR remote controller through this window.
The IR remote controller must be in the direct line of sight
of this window when it is in use.

Freeze control

— Press this button to display (or record) a

still image of the scan-converted picture from both display
outputs. (See “Rear Panel Features” and “Cabling” for
information on these outputs.) The freeze LED indicator
lights while this control is active. To turn this feature off,
press the Freeze button again. Freeze affects both outputs
simultaneously. No matter what the format is (RGB,
component, S-video or composite video), the image will be
“frozen”. The image on the local monitor will not be
“frozen”.

All controls except Freeze will be locked on both the front
panel and the IR remote control while Freeze mode is
active. Press the Freeze button again to turn off Freeze
mode and unlock the other controls.
