WARNING: TO REDUCE THE RISK OF ELECTRIC SHOCK DO NOT REMOVE COVER (OR BACK). NO USER

SERVICEABLE PARTS INSIDE. REFER TO QUALIFIED SERVICE PERSONNEL.

The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert
the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure
that may be of sufficient magnitude to constitute a risk of electric shock to persons.

The exclamation point within an equilateral triangle is intended to alert the user to the pres­ence of important operating and maintenance (servicing) instructions in the literature accom­panying the appliance.

WARNING:

TO PREVENT FIRE OR SHOCK HAZARDS, DO NOT EXPOSE THIS PRODUCT TO RAIN OR MOISTURE.

POWER CORD POLARIZATION:

This product is equipped with a 3-wire grounding-type alternating current line plug. This plug will fit into the
power outlet only one way. This is a safety feature. If you are unable to insert the plug fully into the outlet,
contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the three-wire
ground type plug.

NOTE TO CABLE/TV INSTALLER:

This reminder is provided to call the cable TV system installer’s attention to Article 820-40 of the National
Electric Code (U.S.A.). The code provides guidelines for proper grounding and, in particular, specifies that the
cable ground shall be connected to the grounding system of the building, as close to the point of the cable
entry as practical.

Page 10

Macintosh Environment

Setting your computer for optimum picture output in the Macintosh
operating system environment

MACINTOSH Environment

The following is a step-by-step procedure for set­ting your computer picture output to optimum dis­play quality.

1. Plug your computer in to the Presentation TV.
Turn On the TV and then the COMPUTER.

2. Open your CONTROL PANEL by choosing under
the APPLE icon or by clicking on your HARD
DRIVE icon. If you choose the HARD DRIVE
icon, you’ll have to open your CONTROL PANEL
through the SYSTEMS FOLDER.

3. After you have located the CONTROL PANEL,
click on VIEWS. This is where you will make
changes for Presentation display.

4. Change the FONT to one that is appears well on
a television. We would suggest that you use
TIMES BOLD. Now, change the FONT SIZE to 18
or better.

Each time that you use the TV with your com­puter, you will simply change the FONT and
SIZE through the CONTROL PANEL and VIEW. You
have changed the appearance of all your folders
but NOT your applications.

VIEWING FOR PRESENTATION vs. PRIVATE

1. When viewing an application, such as EXCEL or
WORD, you will have to change the appearance
of each application.

2. Once the application has been opened, just
change the view from 100 percent to a selec­tion over 150 percent. This will not permanent­ly effect your document. Once you have com­pleted your presentation, simply reduce the size
back down to 100 percent viewing ratio.

3. To enlarge the ICONS of the application, click
on VIEW and then select TOOLBARS. Slide down
and highlight CUSTOMIZE with your mouse, then
click.

4. A file folder will now “pop-up”. Now select
OPTIONS and then click on LARGE ICONS. This
will only enlarge the ICONS on your menu
palette. Due to a less flexible platform, you
will not be able to effect the fonts/size on the
Menu Bar.

This Zenith Presentation TV is a high-quality, low
cost alternative to a true SVGA monitor.
