Introduction
The MEMRECAM GX-3 is designed to analyze images moving at speeds not
visible to the naked eye.
The MEMRECAM GX-3 has a unitized configuration with an IC memory as the
storage medium and so is a high speed digital camera that possesses the
identical compact nature of a high speed film camera, the same immediate
playback function of a high speed video camera, and can handle the digital
data from all of the images after recording.
The MEMRECAM GX-3 easily performs the high speed photography
necessary for high speed techniques. Photography and analysis without the
use of a computer is possible with the included software containing the
functions of remote operation from a computer with the simple operation of the
included remote controller, image storage to a USB compatible external
storage medium using the USB port and live image display using the
viewfinder or monitor.
The MEMRECAM GX-3 is designed for high speed and superior image quality
requirements. Photography at a resolution of 1280 x 1024 pixels is possible
with a photographic speed of 1,500 frames per second. High speed
photography is possible up to 198,000 frames per second (4(H) x 16(V)) using
a split frame. Also, high speed image transmission to the control computer can
be performed according to the high speed network (10BASE-T, 100BASE-TX,
1000BASE-T).
The MEMRECAM GX-3 performs high speed photography in demanding test
environments, as well as possessing properties resistant to magnetism.
This user's manual provides the specifications, operating methods, interface
with peripheral equipment and system expandability information to use the
MEMRECAM GX-3 with these features.

Handling Precautions
Safety alert symbol
This is a「Safety Alert Symbol」.
This symbol is intended to alert the user of items or operations that could be
dangerous to oneself or others during the use of this device. Carefully read the
messages accompanying this symbol and follow the instructions to safely use this
device.
Grounding terminal symbol
This symbol is displayed in areas with grounding terminals. If not grounded, electrical
shock may occur when metal or other parts of the device are contacted. Do not
ground, due to the dangers involved.
If a 3P-2P conversion plug is used to connect to the power outlet, connect the
grounding wire of the conversion plug to the grounding terminal.
High voltage warning symbol
This symbol is displayed in areas of dangerously high voltage.
Remove the power cable from the outlet when replacing fuses.
Do not remove the cover of this device. Electrical shock could occur if this device is
handled with the cover removed even if the power switch is OFF.
High temperature caution symbol
This symbol is displayed in areas of dangerously high temperature.
The device generates the heat and may become high temperature under energizing.
Don't touch the device as much as possible while operating. There is the danger of
the burn.

(00235) - 5 -
Precautions for Use
Caution Verify Power Input
Power input to the system should beAC 100~240V/47~63Hz when using theAC adapter
(option), and DC20~32V when using DC power or batteries. Please verify power voltage,
frequency and polarity prior to connecting to power.
Caution Operating Environment
・Use in locations where the ambient temperature is 0~+40°C and the RH is 30~80%. Use
where there is no condensation.
・Store where the ambient temperature is -10~+60°C and the RH is 20~80%. Store where
there is no condensation.
・Avoid using in locations with smoke, corrosive gases or strong magnetism.
・Do not store in locations subject to direct sunlight, rain or salt water.
・Do not use in locations with excessive dirt, dust, sand or moisture.
Caution Vibration and Shock
In MEMRECAM GX-3, there are no vibration and shock resistant properties requested by
the collision experiment etc.
Please examine GX-1 etc. about use in such an environment.

Caution Handling the Main Camera Unit
The inside of the main camera unit contains parts that are precisely manufactured and
installed. Please keep the screws in the camera cover tightened and do not open the
cover under any circumstances (even if the main camera unit does not operate properly).
It may not be possible to recover the functions of the camera.
Caution Generation of Heat
Heat will be generated during operation of the system but it will not interfere with operation.
If an abnormal amount of heat is generated, turn off the power and unplug from the outlet.
Directly contact the retail outlet or this company.
Caution Handling the Lens Mount
Remove the lens or cap on the lens mount of the camera to view the camera contents. Do
not touch or place items inside. This could damage the optical system, and any dust could
adversely affect the image.
Warning Handling Cables
Turn the power off while connecting or removing cables.
With the power still on, connecting or removing cables could result in a malfunction, or
electrical shock.
Do not put metal parts into the connectors.
Caution Handling the Battery
The MEMRECAM GX-3 is equipped with a standard memory backup battery so does not
place in direct sunlight in vehicles, near fire, on the stove or any location with high
temperatures.
The battery could leak and adversely affect performance of the battery of its life.
Do not use the memory backup batteries for any other purpose. The battery could leak,
generate heat or malfunction.
Contact a retail outlet for replacement memory backup batteries.
Caution Handling When Moving or Transporting
Use the special carrying case for this product when moving or transporting.

(00235) - 7 -
Caution Amplification of Sensor Noise
The temperature of the image sensor used in this product alters the screen noise. This
noise has a pattern that differs from the stationery pattern noise for each sensor.
In this product, noise reduction is performed by correcting the temperature changes as
well as the stationary pattern noise for the sensor.
If a finer image quality is desired, adjust the black balance immediately prior to
photographing.
Depending on the conditions and circumstances of use of the device, there may be malfunctions
other than those listed above. Please carefully read all of the user's manual for the device. Directly
contact the retail outlet if there are questions about this device.
Parts to be Replaced on a Regular Basis
・Clock Battery
The clock battery will last for approximately 8 years. Replacement cannot be made by the user so
please contact the retail outlet or this company.
・Memory Backup Battery
Please replace the memory backup battery approximately one year after purchase. If the discharge
rate accelerates or if there are differences in amount of use, please replace immediately. Replacement
cannot be made by the user so please contact the retail outlet or this company.
Warranty
The warranty period for the MEMRECAM GX-3 is for one year after delivery.
For details, refer to the attached warranty.
