2. WARNING

WARNING

A - - -.....

*

Use of non-TE H KAN parts or modification of any TE H KAN game circuitry may adversely affect the safety of your game, and may cause injury to you and your players.

*

This equipment generates, _ uses, and can radiate radio frequency energy and if not installed and used in accordance with the instruction manual, may cause interference to radio communication. It has been tested and found to comply with the limits for a Class A computing device pursuant to Subpart

J or Part 15 of FCC

Rules, which are designed to provide reasonable proJection against such inter ference when operated in a commercial environment. Operation of this equipment in a residential area is likely to cause interference in which case the user at his own expense will be required to take whatever measures may be required to correct the interference.

*

Players may receive an electrical shock if this game is not properly grounded!

To avoid electrical shock, do not plug in the game until it has been inspected and properly grounded. This game should only be plugged into a grounded 3-wire outlet. If you have only a 2-wire outlet, we recommend you hire a licensed electrician to install a grounded outlet. Players may receive an electrical shock if the control panel is not properly grounded! After servicing any parts on the panel, check that the grounding clip is firmly secured to the metal tab on the inside of the control panel. Only then should you lock up the game.

*

Before connecting the game to the AC power source, verify that ' the proper voltage-selection plug is installed on the game's power supply.

*

To avoid electrical shock, disconnect the game from the AC power source before removing or repairing any part of the game. When r~moving or repairing the video display, extra precautions must be taken to avoid electrical shock because high voltages may exist within the display circuitry and cathode-ray tube, (CRT) even after power has been disconnected. Do not touch internal parts of the display with your hands or metal objects! Always discharge the high voltage from the

CRT before servicing this area of the game. To discharge the CRT: attach one end of a large, well-insulated, 20-kV jumper to ground. Momentarily touch the free end of the grounded jumper to the anode by sliding it under the anode cap.

Wait two minutes and discharge the anode again.

3. CAUTIONS

( 1) Care in Usage

• Care should be taken to avoid dragging or dropping the machine when transporting to prevent damage to the CRT.

• Use fuse of indicated rating.

• As high voltage is present in the monitor and TV PCB, adjustments or repairs should be left up to a serviceman and should never be touched by the layman.

(2) Care in Handling

• Always turn off the power supply switch before handling.

• Avoid inserting and pulling the plug in rapid succession.

• Do not check the IC board circuit with a tester.

• Avoid rough handling in transportation; the picture tube is fragile.

(3) Installation

• As the video game is for "indoor use", do not instal I outdoors.

• When installing, avoid the following places. a) Near indoor pools or showers b) Where leaks exist c) Under direct sunlight d) Near heaters or other heat emitting devices e) Near hazardous items (volatile fluids, gas cylinders, etc.) f)

Where vibrations are severe (near construction sites where jack hammers, etc. are used.) g) Inclined places h) Near fire extinguishing equipment i) Near emergency exits

• Caution: a) To prevent electric shock do not use this (polarized) plug with an extension cord, receptacle or other outlet unless the blades can be fully inserted to prevent blade exposure.

In case the machine does not work properly after the power switch is turned on, make sure the proper voltage exists at the line cord.

- 3 -

TEHKAN

(4) Trouble Shooting

When it is believed that trouble has developed, always confirm the following items.

• Is the fuse intact? (Always use fuse of the designated rating.) When th@ replaced fuse burns out again, this will indicate that another component is defective .

• Are there any poor connections (connectors) or open circuits? Special care must be taken to ensure connectors are firmly inserted. Troubles due to faulty contacts can be considered from various , sources.

Note: Always turn off the power when inserting or removing the connectors.

• There will be times when a normal picture will not appear when the power supply switch is turned on. As this may sometimes be corrected by a setting of the control circuit, turn power supply switch on and off several times.

• When testing meters, switches, etc. with a tester, always first pu 11 the IC board connectors.

(5) Caution

"This equipment generates and uses radio frequency energy and if not installed and used properly, that is, in strict accordance with the manufacturer's instructions, may cause interference to radio and television reception. It has been type tested and found to comply with the limits for a Class A computing device in accordance with the specifications in Subpart

J of Part 15 of FCC Rules, which are designed to provide reasonable protection against such interference in a residential installation.

However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient the receiving antenna

• Relocate the computer with respect to the receiver

• Move the computer away from the receiver

• Plug the computer into a different outlet so that computer and receiver are on different branch circuits.

If necessary, the user should consult the dealer or an experienced radio/television technician for additional suggestions. The user may find the following booklet prepared by the Federal Communications Commission helpful:

"How to Identify and Resolve Radio-TV Interference Problems". This booklet is available from the

US Government Printing Office, _
