• Plug the computing device into a different AC outlet so that the computing device and receiver are on different
branch circuits.
• Disconnect and remove any
1/0 cables that are notbeing used. (Unterminated I/Ocablesarea potential sourceof
high RF emission levels.)
• Unplug and remove anycircuitboardsthatare notbeing used. (Here again, unterminatedcardscan be asource
of
potential interference.)
• Be certain thatthe computing device is plugged into grounded outlet receptacles. (Avoid using AlC cheater plugs.
Lifting

COLOR VIDEO MONITOR
INTRODUCTION
Congratulations on your purchase ofthe Zenith Data Systems
Color Video Monitor. This Monitor can display RGB colorvideo
signals; the red, green, and blue signals necessary to produce
color; to provide you with a professional visual presentation.
Theyconnectdirectlytothe ColorMonitorand therefore usually
produce a better display than other monitors that use
RF mod-
ulatedsignalsthat haveto bedemodulated
-like in atelevision
set.
A high-quality color picture is assured by the automatic color
processing circuits that have been engineered intothe Monitor.
Thevertical and horizontal portions ofthe display are held rock-
steady by specialized circuits, so that the customary vertical
and horizontal hold controls are not needed.
Your new Color Monitor has been carefully adjusted and fine-
tuned at the factory for a good display. To obtain the most use
and satisfaction from it, please take a few minutes to read this
Manual before you use your new Monitor.

UNPACKING
Carefully remove the Monitorfrom its packing material; lift itout
by its handle. To grasp the handle, referto Pictorial 1and press
down on either end of it.
INSTALLATION
Location-Choose a placeforyour ColorMonitorwhere there
is a comfortable light level for viewing the screen. Sunlight or
bright lightshould notfall directlyon thescreen, asthiswill have
a tendencyto "wash out" the display and makeviewing difficult.
Also allowfor a comfortable viewing distance and select a good
solid surface to set the Monitor on.
Ventilation -Proper ventilation is important becal,lse it helps
keep your Monitor running cool, and cool operation almost
always extends the life of
an electronic product. On the bottom,
back, and top of the cabinet there are slots which permit air to
flow. Therefore, be sure you do not enclose the cabinet or
otherwise obstruct the ventilation slots.
Power-Your Monitor is designed to operate on 120volts, 60
Hertz AC (unless you purchased the ZVM-134E, which
operates on 220 volts 50 Hertz AC). Choose a location near
such
an AC outlet and NEVER attempt to operate the Monitor
on DC.
Warning -Do not expose this Color Monitor to rain or
moisture, and never operate the unit if liquid has been spilled
into
it. If this happens, have your Monitor checked by a service
technician before you use it again. A fire
or an electric shock
could result ifyou do nottake this precaution.

IN CASE OF DIFFICULTY
All ZDS Computer hardware and software products were
designed to work together as a complete system. Proper
operation can be assured only when your Monitor is used with
ZDS designed or approved accessories. ZDSdoes notassume
the responsibility for improper operation resulting from custom
interfacing, custom software, or the use of accessories not
approved byZenith Data Systems.
All the Monitor components have been wired and tested by
ZDS. If you encounter any malfunction during the warranty
period, call your Zenith Data Systems dealer or authorized
Zenith Data Systems repair facility to arrange for service.
Do
NOT attempt to service this Monitor yourself during the
warranty period; to do so may void the warranty.
You mayhaveout-of-warranty products repaired byyourZenith
Data Systems dealerorauthorized Zenith Data Systems repair
facility. You may wish to obtain a maintenance contractforyour
Monitor.
If you cannot locate a Zenith Data Systems dealer or repair
facility, call 1-800-447-4700 (in Illinois, 1-800-322-4400)forthe
name and location ofthe one nearest you.
If you have difficulty with the video produced by your Color
Monitor, the trouble may be:
•
In the Interconnecting cable.
•
In the Computer.
•
In the Color Monitor.

Page 10
COLOR VIDEO MONITOR
First, determine which component is at fault by making the
following tests:
• Check to see that the Monitor and Computer are plugged into
aworking
AC power source, and turned on.
• Be sure that the cable is properly plugged into both the
Monitor
and Computer. Then move the interconnectingcable
back
and forth, particularly near the ends. Ifthe trouble varies
or
is intermittent, the cable is defective and must be replaced.
• If another Computer is available, connect the Monitor to it. If
the Monitor now functions properly, the original Computer is
defective. However, if the Monitordoes notfunction properly,
then it may be defective.
IMPORTANT:
If you contact a Zenith Data Systems dealer or
authorized Zenith
Data Systems repair facility, try to list the
following information about your Computer System. If will help
them to diagnose and repair your Monitor.
A. The problem you are having.
