Important Information Regarding Use of Video Games, Computers, DSS or Other Fixed Image Displays.

The extended use of fixed image program material can cause a permanent "shadow image" on the picture tube. This

background image is viewable on normal programs inthe form of a stationary fixed image. This type of irreversible picture

tube deterioration can be limited by observing the following steps: A. Reduce the brightness/contrast setting to a minimum viewing level.

B. Do not display the fixed image for extended periods of time. C. Turn the power off when not in actual use.

NOTE: The marking or retained image on the picture tube resulting from fixed image use is not an operating defect and as

such is not covered by Warranty. This product is not designed to display fixed image patterns for extended periods of

time.

Installation

Receiver Location

This unit is intended to be used with an optional stand or entertainment center. Consult your dealer for available optioJLs. Locate for comfortable viewing. Avoid placing where sunlight or other bright light (including reflections) will fall on the

screen. Use of some types of fluorescent lighting may reduce remote control transmitter range.

Adequate ventilation is essential to prevent internal component failure. Keep away from areas of excessive heat or

moisture.

To insure optimum color purity do not position magnetic equipment (motors, fans, other speakers, etc.) nearby.

Optional External Equipment Connections

The Video/Audio connections between components can be made with shielded video and audio cables. For best perfor-

mance, video cables should utilize 75 ohm coaxial shielded wire. Cables are available from your dealer or electronic supply house.

Before you purchase any cables, be sure you know what type of output and input connectors your various components require. Also determine the length of cable you'll need.

AC Power Supply Cord

CAUTION: TO PREVENT ELECTRIC SHOCK, MATCH WIDE BLADE OF PLUG TO WIDE

SLOT OF AC OUTLET AND FULLY INSERT. DO NOT USE THIS (POLARIZED) PLUG

WITH A RECEPTACLE OR OTHER OUTLET UNLESS THE BLADE CAN BE FULLY

INSERTED TO PREVENT BLADE EXPOSURE.

Remote Control Battery Installation

Batteries: Use two "AA" batteries.

1. Remove the battery compartment cover on back of the remote.

2. Install the batteries in the battery compartment. (Polarity (+) or (-) must be correct.)

3. Reattach the battery cover.

EUR501371

For frequent Remote Control users, replace old batteries with Alkaline batteries for longer life.

Precaution on Battery Use

Incorrect installation can cause battery leakage and corrosion that will damage the Remote Control Transmitter.

Observe the Following Precautions:

1. Batteries must be replaced as a pair.

2. Do not combine a used battery with a new one.

3. Do not mix battery types (Example: "Zinc Carbon" with "Alkaline").

4. Do not attempt to charge, short-circuit, disassemble, heat or burn used

batteries.

5. Battery replacement is necessary when Remote Control reacts

sporadically or stops operating the Receiver.
