2 Safety First!
Please take CAREFUL NOTE of the following SAFETY ISSUES.
Due to medical safety reasons, this product should not be used by the following
persons:
2.1 Individuals with Epilepsy
Individuals who have been diagnosed with Epilepsy, or who have a personal or
family history of Epilepsy, should not use this product because it may trigger epileptic
seizures. If you have any doubts about this, consult with a medical doctor and/or
neurologist before using the product.
2.2 Individuals Younger than 10 Years of Age
The eyes of a person younger than 10 years of age are still developing the ability to
focus. Therefore, individuals younger than 10 years of age should not use this
product because it may adversely affect the focusing ability of their eyes.
2.3 Termination of Usage
STOP using this product IMMEDIATELY if:
•You experience discomfort of any nature
•You develop a headache
•You start feeling nauseous
•You start experiencing vertigo (dizziness)
Do not wear the product for longer than one hour at a time. When this
period has expired, take a break for at least 10-15 minutes before wearing
the device again. A warning to stop using the device will appear in the
displays after two hours.
2.4 Electrical Safety
•Make sure that the line voltage of the power adapter (AC adapter) is the same as
the line voltage of the country where the HMD will be used. For example if the line
voltage of the power adapter is 100-120V AC, it should not be used in a country
where the line voltage is 220-240V. Using an incorrect power adaptor may cause
it to explode.
•Unplug the power adapter when the unit is not in use.
•Always use the designated AC power adapter (included with the product).
•To prevent electric shock and/or fire, do not unplug by pulling on the cord and do
not touch the power plug with bare hands.
•Do not use the product in a wet environment (such as a bathroom).
2

2.5 Cleaning the Product
•Always unplug the power adapter before cleaning the product to prevent electric
shock and/or fire.

•To remove stains or dirt, wipe the HMD with a soft cloth dampened with a neutral
detergent.
•Do not use solvents like paint thinner, benzene or other products that may
damage the surface of the product.
2.6 Personal Hygiene
•Alcohol wipes are useful for cleaning the HMD between users for multiple user
applications. Alcohol will remove skin, oil and makeup that has been transferred
to the HMD.
•The front, back and top foam inserts should also be cleaned or replaced as
necessary. Soak the foam inserts in a mild detergent, rinse lightly and leave in the
sun to dry.
•There have been anecdotal reports of lice/pest transmission between HMD users
in multiple user applications. There are sprays available that will kill the lice on
furniture and clothing. These sprays are hazardous and you need to judge the
benefits versus the risks of using these sprays.
•Make sure to switch the HMD off and to cover the optics before wiping it or

3D Modes: 3D1 and 3D2
The 5DT HMD 800-26 3D supports two 3D modes. In both modes, full resolution
frame sequential image input is required.
Figure 13 – The 3D Mode Selection OSD menu
Mode 1: DDC Line Protocol
The DDC line protocol is used principally by the nVIDIA Stereo drivers. If nVIDIA
stereo drivers are active and outputting a 3D signal, the headset will automatically
detect the DDC line and stay locked on the signal.
Note: The DDC Line Protocol is the highest priority 3D function. If this signal is
present, the headset will function correctly in either 3D1 or 3D2 modes.
Mode 2: Frame Sequential Stereo
With frame sequential stereo input the user can select either 3D1 or 3D2 to activate
the frame swapping function. However, if the image on the headset is in reverse
stereo, simply switch to the opposite mode.

Appendix A - Troubleshooting
There is no video Signal
•Check that the power adapter is plugged in and the POWER LED is lit.
•Check that the resolution of the input signal is 800x600.
•Check that the video cable is plugged into the PC VGA output port.
•Check that the screen refresh is set up correctly. The refresh rate should be
60Hz for 2D mode.
The picture is dark and fuzzy
•Make sure that the external source is connected and is turned on.
•Adjust the brightness of the display.
There is no sound
•Check that the volume is not set to zero.
•Check that the control is not muted.
The color appears incorrect
•Check the color control settings.
•Check that the VGA connector is properly inserted.
The image rolls, has static or is jumpy.
The 5DT HMD 800 is looking for a very precise 800 x 600 input signal at 60Hz. Some
computers may output a signal at a frequency other than 60Hz despite the fact that
your computer is set at 60Hz. Many computer monitors offer a “view meter” function
that will tell you the exact signal output. See your monitor manual for details. Try
raising or lowering your refresh rate slightly to see if this solves the problem.
The image flickers in 3D mode.
The 5DT HMD 800 operates at a refresh rate that is double the input refresh rate up
to 60Hz. The headset will operate at the input refresh rate if the input rate is above
60Hz. If you experience image flicker, make sure the input refresh rate is 60Hz or
less. Alternatively, reset the refresh rate on your computer to a minimum of 85Hz,
preferably 100Hz or higher. Generally, at a refresh rate above 85Hz, the human eye
should not be able to detect image flicker.
