7 - 3 REPLACING THE DIMM BOARD BATTERY PACK
   Do not disassemble the battery pack and the batteries.
      If you should fail to observe this instruction, the internal wires and/or 
protective devices may be damaged; as a result the safety system may not 
function when discharging and recharging, eventually causing an overheating, 
fire and explosion. If you should disassemble the batteries, the generated 
gases may harm your throat and the negative plate may overheat and make a 
fire.
   Do not make an external short circuit of the battery pack and the batteries.
      If you should fail to observe this instruction, the batteries may overheat, make 
a fire, and explode.
   Do not fire the battery pack and the batteries.
      If you should fail to observe this instruction, the batteries may make a fire and 
explode.
      Do not leave the battery pack and the batteries nearby the heat source (fi re or 
heater) or under the intense direct sunlight and flaming sun. If you should fail 
to observe this instruction, the batteries may reduce the service life and in the 
worst case may overheat, make a fire, and explode.
   Do not leave the battery pack and the batteries in water or seawater. Also do 
not apply water or seawater onto the battery pack and the batteries. If you 
should fail to observe this instruction, the internal wires and/or protective 
devices may be damaged; as a result the safety system may not function 
when discharging and recharging, eventually causing an overheating, fire and 
explosion. Also water may be electrolyzed into oxygen and hydrogen, and 
eventually the battery's sealed section may be corroded and the internal liquid 
may leak.
   Do not solder on the battery pack's terminals.
      If you should fail to observe this instruction, the armor may be heated 
and melted or the internal wires may be damaged, eventually causing an 
overheating, fire and explosion. Also, when the battery's temperature reaches 
to 100º or more, the battery may leak its internal liquid due to destruction 
of its plastic parts (gasket, separator, etc.), or may overheat, make a fire, or 
explode due to internal short-circuit.
   Do not insert or connect the battery in a reversal polarity.
      If you should fail to observe this instruction, the battery may be externally 
short-circuited and eventually overheat, make a fire, or explode, depending on 
the device you connect with.
When handling the battery pack, observe the following instructions. If you do not observe the 
instructions described by this book, the Sega bears no responsibilities against any resulted 
problems.
Prohibitions and Cautions to Handle the Battery Pack
WARNING! 
						

							58www.seuservice.com59www.seuservice.com
   Do not tightly seal the battery pack when installing it onto an external device. 
      Flammable gas is generated from the battery when its safety mechanism has 
functioned. If you should fail to observe the above-described instruction, 
sparks from motors, switches, etc. may cause the gas to fire. Therefore, install 
the battery pack so that the gas can be quickly released from the external 
device.
   Do not use the battery pack for the device/usage other than this game system.
      If you should fail to observe this instruction, the battery and/or the device may 
be damaged due to non-applicable specifications.
   Do not strike a nail in, hammer, step on, or apply any other forms of pressures 
and shocks on, the battery.
      If you should fail to observe this instruction, the battery may be deformed. As 
a result, the battery may burst at its sealed sections to leak the internal liquid, 
or may be short-circuited internally to overheat, make a fire, and explode.
   Do not use a battery charger because any battery charger is not usable for this 
battery pack.
      If you should fail to observe this instruction, the gas may be suddenly 
generated in the battery and eventually the battery may overheat, make a fire 
or explode.
   If the battery in use or in keeping shows an abnormal indication (deformation, 
change of color, bursting of the armor cover, etc.), immediately stop using or 
keeping it. If it leaks and smells abnormally, immediately keep it away from 
fire and put it in a safety box.
   If the liquid leaks from the battery and gets in your eyes, do not rub your eyes 
but immediately wash them with clean water (city water etc.); and consult a 
medical doctor for a treatment. If you should fail to observe this instruction, 
the liquid may harm your eyes.
   The battery pack armor (a polyvinyl chloride tube) may be damaged or 
deformed by external force or heat. When transporting the battery pack or 
replacing it with a new one, therefore, be careful not to drop or excessively 
shock it. Do not continue to use any damaged or deformed battery pack. If 
you should fail to observe this instruction, the battery may overheat, make a 
fore, or explode.
   The battery pack contains a printed circuit board (PCB) for protective 
circuitry. It may be destroyed by the static electricity. When handling or 
servicing the battery pack, therefore, take preventive measures against the 
static electricity. 
      If your battery pack has shown destruction of a protective circuitry PCB, do 
not continue to use it. If you should fail to observe this instruction, the battery 
may overheat, make a fore, or explode.
   When wiring the battery pack to a device, be careful not to apply excessive 
force onto the connectors and lead wires. The battery may overheat, make a 
fire, or explode if the connectors and lead wires are damaged.
   Do not do away with the used battery packs carelessly because they may 
contaminate the environment. Submit them to an industrial waste disposal 
plant.
   Pack the used battery packs and thereby avoid damaging them, before 
delivering them to an industrial waste disposal plant.

When a GD-ROM readout time seems to be longer than before, the cause may be a reduction of 
DIMM board battery pack's charge. Usually, the DIMM board battery pack reaches its service 
life about 16 months after starting to use. 
Do not use a battery charger because any battery charger is not usable for this battery pack.
Instead, replace the battery pack with a new one as follows:
 Refer to "7-1 REMOVING/INSTALLING THE DIMM BOARD CASE" and remove the 
DIMM BOARD CACE from the TRIFORCE.
 Using a flat-blade screwdriver, lift up the battery cover and thus remove it from the DIMM 
board case.
 Press the tab of the battery pack connector and pull it; thus remove it from the DIMM board.
 Firmly connect the connector of a new battery pack into the DIMM board.
 Return the battery cover to the DIMM board case.
 Refer to "7-1 REMOVING/INSTALLING THE DIMM BOARD CASE" and fix the DIMM 
BOARD CACE to the TRIFORCE.
Submit the used battery packs to an industrial waste disposal plant. Thus they must be disposed 
according to the local laws and regulations.

Handling the GD-ROM Disc
   Do not contaminate the discs with your fingerprints 
or dust particles. Contaminated discs may lower audio 
and video quality.
   When cleaning the discs, do not use volatile chemicals 
(benzine, thinner, etc.), cleaning sprays, and antistatic 
agents.
   Do not use cracked, warped, or damaged discs.
      Do not attach papers or seals onto the discs; do not 
scratch the discs.
      Do not use the discs with a sign of peeled seals, tapes, 
etc.
      Observing these instructions, do not insert such a non-usable disc into the 
GD-ROM drive. Otherwise the inserted disc can not be ejected. 
   When cleaning a heavily contaminated disc, use clean cloth that has been 
soaked in water and squeezed. Then remove moisture with dry cloth.
   When holding a disc, be careful not to contaminate it with your fingerprints.
7 - 4 GD-ROM DISC
How to Hold a Disc
With both hands:
Put your thumbs and forefingers of 
both hands on the disc's 4 edges.
With one hand:
Insert your forefinger into a central hole 
and at the same time put your thumb and 
middle finger on the disc's 2 edges.
Use clean cloth to wipe 
the disc gently into a 
radial direction.
