2. WARNING
..-----A 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 interference 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)
•
•
•
•
(3)
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.
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.

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, _Washington, D.C., 20402, Stock No. 004-000-00345-4.

I
( 1) Push Button Blade Switch
• Adjust the blade switch contacts for correct gaps.
• When the blade is bent, straighten it by using the blade adjusting rod.
- - A WARNING A - To prevent an electrical shock hazard, unplug the game prior to performing any maintenance.
Blade Adjuster
• Take out carbon deposits on the blade switch by using a clean cloth, etc.
(2) Inspecting the Controlball
• Check the controlball to see if its roller shafts have worn.
In case there is too large a clearance between the C.B spacer and the ball due to the excessive wear
of the roller shaft, replace either the roller shaft A or the roller shaft B.
• Lubricate the control ball's ball bearings every month or 2,000 credits.
After wiping out dust, etc. cleanly, place 2 or 3 drops of light duty oil on each~ of 6 ball bearings.

• The game is not credited even when a coin is inserted.
a) Check if the coin is stopped up.
or the coin micro-switch is malfunctioning.
b) Check if the coin mechanism

• The coin counter does not work.
a) Check if the coin credit PCB is malfunctioning, or there is improper contact for each connector.
b) Check if the coin counter itself is malfunctioning.
• 'Player Select' cannot be performed.
a) Check if there is improper contact for the push button blade switch.
b) Check if there is improper contact for the J3, J2 connectors.
• The control ball itself does not rotate smoothly.
a) Check if there is something wrong with the ball bearings (see page 10, 'Maintenance').
b) The controlball ceases to rotate smoothly when there occurs contact between the ball and C.B
spacer, due to the loosening of 4 carriage bolts and nuts which fix the ball on the control panel.
• The control ball does not work.
a) Adjust the interval between 2 photointerrupters of the photo PCB.
b) Check if the disc plate is bent, or there is improper contact for each connector.
• Cannot perform 'Kick~.
a) Check if there is improper contact for the push button blade switch, or each connector.
