DESCRIPTION  
The PMC21A is a high-resolution color monitor that can be used in desktop applications or  
rack mounted using the bezel rack mount that is provided as a standard accessory. The  
rack mount is constructed of steel, has a black finish, and occupies 11 rack unit spaces. It is  
supplied with eight flat-head screws to attach the rack mount to the monitor, and four 10-32  
screws to attach the rack mount to a console.  
The monitor supports NTSC and PAL video, as well as 120 VAC and 230 VAC input power.  
An automatic switching system makes all the necessary changes for adapting to the re-  
quired formats. Manual selection is not required. A separate power cord is supplied for each  
voltage input.  
The PMC21A features audio input and output, and has a steel housing and front panel con-  
trols. The S-VHS high-resolution video (420 horizontal lines at center) and digital comb filter  
circuitry add to the superior picture quality.

OPERATION  
FRONT PANEL CONTROLS  
Refer to Figure 6 for front panel controls.  
1. Press the POWER switch to turn the monitor on. The power LED lamp above the  
switch will illuminate when the power is applied.  
2. Press the VIDEO/S-VHS switch to select the S-VHS mode if the S-VHS input jack on  
the rear of the monitor is used. Otherwise, select the VIDEO mode. The mode is mo-  
mentarily displayed on the upper right portion of the monitor screen at the time it is se-  
lected.  
3. Adjust the VOLUME control for the desired audio level. Turn the control clockwise to in-  
crease and counterclockwise to decrease.  
4. Adjust the CONT. control for the desired overall contrast. Proper adjustment will allow  
maximum gradations between the darkest and lightest picture contrast. Turn the con-  
trol clockwise to increase and counterclockwise to decrease.  
5. Adjust the BRIGHT control for the desired overall display brightness. This control is  
also useful to compensate for differences in surrounding area lighting. Turn the control  
clockwise to increase and counterclockwise to decrease.  
6. Adjust the COLOR control to set the color saturation level. Turn the control clockwise  
to increase and counterclockwise to decrease.  
7. Adjust the SHARP control to obtain the clearest picture.  
8. Adjust the TINT control for the proper color phase or flesh tones. When turned clock-  
wise, the skin tone becomes greenish. When turned counterclockwise, skin tone be-  
comes reddish.  
PASSIVE LOOPING  
Passive looping is accomplished when two or three monitors are connected in series (see  
Figure 4) and a looping signal is sent through the IN and OUT connectors of one monitor  
and to the next in series. Unless you want to view the monitor(s), none of them need to be  
turned on for passive looping to function.

MAINTENANCE  
If the quality of the picture is poor and cannot be improved by making adjustments on the  
front control panel, inspect all system connections and cable runs.

able parts are inside. Refer servicing to qualified personnel or contact the Pelco Customer  
Service Department for assistance. Refer to the Warranty and Return Information section.  
Clean the cabinet with a cloth slightly dampened with mild household detergent only. Use a
