1. Introduction
Congratulations on your purchase of a NEW ULTRA VGA monitor. One of
the most versatile monitors available today, the TC-1428 automatically
adjusts its vertical and horizontal scanning frequencies to those of your
computer’s graphics adapter or video chip sets. The TC-1428 provides
crisp text and vivid color graphic displays when used with NEW ULTRA
VGA compatible graphics adapters (see specifications).
2. Precautions
1. To prevent electric shock, do not remove screws or cover.
There are no user-serviceable parts inside the monitor. Refer servicing
to qualified service personnel.
DO NOT REMOVE THE TILT/SWIVEL BASE!
2. The input power source:
The TC-1428 is designed to be suitable for low input voltage (100-
125V) and high input voltage (200-240V) areas.
3. The monitor is equipped with a three-pronged grounding plug which will
only fit a grounded power outlet.
This is a safety feature. If you are unable to insert the plug into the
outlet, contact an electrician.

Tilt and Swivel Operation:
The swivel range is normally limited to a range of 45 degrees to the right or
left of the front position (marked by a small molded pip on the top front
bottom of the base).
The tilt range is normally limited at an angle of -5 degrees forwards and +
15 degrees backwards. This allows you to set the screen angle to the
viewing position most comfortable to you.

Your monitor has two connecting cables: a Power Supply Cord, which
connects to a wall outlet, surge protector or other power source, and a
Signal Cable, which connects to the graphics adapter of your computer. To
insure safety and correct operation, always follow these four steps when
connecting the monitor:
1. Disconnect the power supply cords from your computer and monitor.
2. Connect the signal cable from the monitor to the graphics adapter of
your computer. The connector is shaped so that it will only fit when
properly aligned.
3. Secure the connection by tightening the two screws on the connector.
4. Plug the power supply cords of the computer and monitor into an AC
outlet.
