GD-ROM DISC
FIG. 3. 5
15
3 - 6 CONNECTING THE POWER
The disc in the GD-ROM drive starts to turn when the power is connected. If you
open the GD-ROM drive lid in this instance, the disk may jump out causing
danger. Disconnect the power in advance, therefore, when opening the lid. Do not
open the lid immediately after disconnecting power, because the disk has inertia
and can continue turning.
STOP Readout time varies depending on the charge of the DIMM board battery
pack. It may be as long as several minutes when the power is connected for
the first time or reconnected after a long-term power disconnection.
IMPORTANT Readout time varies depending on the game you play.
1 After making sure that the system has been correctly assembled, connect the power to the cabinet.
3 Make sure that the system starts to read out the game from the GD-ROM. Percentage is displayed
during readout.
4 Make sure that a NAOMI GD-ROM SYSTEM logo reappears several minutes after readout.
• If an error message appears, immediately disconnect the power to the cabinet. Referring to
the Section 4, "ERROR MESSAGE," take necessary actions and reconnect the power.
• When a readout time seems to be longer than before, the cause may be a reduction of DIMM
board battery pack's charge.
The DIMM board battery pack reduces its maximum charge each time when it is discharged/
recharged. After discharging/recharging of about 500 times, the maximum charge may be
only 70 to 80% of the initial charge. In other words, the DIMM board battery pack reaches
its service life about 16 months after starting to use, based on that you connect and
disconnect the power everyday. If this is the case, therefore, refer to the Section 3-7,
"REPLACING THE DIMM BOARD BATTERY PACK" to replace the DIMM board
battery pack.
16
3 - 7 REPLACING THE DIMM BOARD BATTERY PACK
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.
Do not disassemble.
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 a short circuit.
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 or heat.
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 (fire 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 apply water or seawater.
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 or heat.
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 100 Celsius 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 in a reversal polarity.
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.
17
Do not tightly seal.
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 for other applications.
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 deform or shock.
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 recharge.
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.
18
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:
1 Using a Phillips-head screwdriver, lift up the battery cover and thus remove it from the DIMM
board case.
2 Press the tab of the battery pack connector and pull it; thus remove it from the DIMM board.
3 Firmly connect the connector of a new battery pack into the DIMM board.
Submit the used battery packs to an industrial waste disposal plant. Thus they must be disposed
according to the local laws and regulations.
