1.Mounting Brackets
This line of Monitech Product has Mounting brackets that you will
attach onto the side of our monitor by unscrewing the screws on
the side and placing the brackets on by screwing in the screws that
you just removed. These brackets help you mount the monitor to
the old CRT frame of your application.
Take the set of
brackets out of the
monitor box. The
mounting ears should
be towards the back
of the monitor.
Use a screwdriver to
unscrew the screws
on the side of the
monitor.
Place the brackets
where the slots are.
Use the screws
previously taken off to
fasten the brackets.

2. Secure a video signal.
Once you have mounted your new Monitech LCD into
your control panel with the video and power cables
attached, the monitor will power up automatically.
It should also start receiving the video signal from your
machine. If you are getting no video signal, your screen
will be blue. Make sure the video cable is secured. To be
sure, unplug and reinsert.
3. Start with the 3-button menu.
Now that you have your video signal, use the 3 buttons on
the back of the LCD to optimize the video for your specific
machine. IMPORTANT: ignore the top 6 buttons for now.
