Adjustments to front panel features and controls do not affect the local monitor.

1Power/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.

2IR 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.

3Freeze 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.

3+ 11 Executive mode (Freeze + Size) — Press the Freeze control together with the Size button for

2 seconds to activate Executive mode. Executive mode 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.

4Freeze indicator LED — This LED lights green to indicate that the freeze feature is active.

5Horizontal (Horz) filtering control — Press this button to choose between the two levels of horizontal filtering to yield the best picture detail.

6Horizontal filtering LEDs — These LEDs light yellow to indicate the selected horizontal filtering level.

7Vertical (Vert) filtering control — Press this button to choose one of the three levels of vertical filtering. Select the setting that yields the least amount of flicker.

8Vertical filtering LEDs — These LEDs light yellow to indicate the selected level of vertical filtering.

9Encoder filtering control — Press this button to choose one of the three levels of encoder filters. Select the setting that gives the best picture detail.

10Encoder filtering LEDs — These LEDs light yellow to indicate the selected level of encoder filtering.

11Size 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. To zoom in, adjust the size so the picture exceeds the 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
