2 Stereo Models
Up to January 2002, the 5DT HMD 800 could only be used in Separate Input 3D
mode. This unit can be identified by its two control boxes. The following points apply
only to users who have this version.
•The package of the 5DT HMD 800 should contain the following:
•2 x SVGA Cables
•2 x RCA to RCA Cables
•2 x Power Adapters
•2 x SCART to RCA Cables
•2 x S-Video Cables
•1 x Audio Cable
•The 5DT HMD 800 Stereo is supplied with 2 power supplies and each control box
must be connected to a power supply.
•To connect your 5DT HMD 800 Stereo to a PC, follow these steps:
a. Connect the supplied D-sub SVGA cable to the 5DT HMD 800 control box and
to the output of your video card for the left hand display.
b. Repeat Step a for the right hand display.
c. Attach the Audio connection as in Figure 5 to the left handed display control
box.
•Please note that if you are using the 5DT HMD 800 Stereo with a single video
output, a video splitter is required, which can be obtained from 5DT. The video
splitter will split the video input into 2 (or more) identical signals that can be
separately fed into the HMD’s inputs.
•For the 5DT HMD 800 Stereo, follow the instructions for adjusting screen flicker
with the 5DT HMD 800, but take note that the right screen flicker will need to be
adjusted with the right control box and the left screen flicker with the left control
box.

3 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:
3.1 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.
3.2 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.
3.3 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)
Take special care to adjust the Interpupillary Distance (IPD) [distance
between the displays]. An incorrect IPD will result in a fuzzy / unfocused
image. Your eyes will strain to correct the fuzzy / unfocused image and
this will normally cause a headache.
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.
3.4 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.

4
•Do not use the product in a wet environment (such as a bathroom).
3.5 Cleaning the Product
•Always unplug the power adapter before cleaning the product to prevent electric
shock and/or fire.
•Remove dust on the headset by using a soft cloth.
•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.
3.6 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
spraying it.

To don the HMD, follow these steps:
a. Place the headset on top of the head and gently slide it down.
b. Adjust the top and back ratchets (see Figure 10) so that the headset is
comfortable and that the displays are as close to the eyes as possible. Take care
not to tighten the back ratchet too much.
c. Adjust the angle of the headset so that the optical display is 5 to 10 degrees
below the horizontal.
d. Adjust the earphones so that they are in a comfortable position.

6.5 Stereo Modes
The 5DT HMD 800 operates in three different stereo modes: Interlaced 3D Mode
(Line Sequential Stereo), Page Flipped 3D Mode (Frame Sequential Stereo) and
Separated Input 3D Mode.
Interlaced 3D Mode (Line Sequential Stereo)
Interlaced 3D Mode is for use with the SVGA video signal. You must use the input
port marked COMMON for this mode.
You can use 60Hz, 72Hz or 75Hz VESA Standard SVGA for this stereo mode.
Stereo is currently not supported for VGA mode.
Interlaced 3D works by assigning different lines of the image to different displays.
The even lines are sent to the left display and the odd lines to the right display as in
Figure 19.
Figure 19 – Interlaced 3D Mode
Page Flipped 3D Mode (Frame Sequential Stereo)
Page Flipped 3D Mode can be used with both the SVGA and composite video
signals. You must use the input port marked COMMON for this mode.
You can use 60Hz, 72Hz or 75Hz VESA Standard SVGA for the PC mode and
NTSC, PAL or SECAM for video sources.
Page Flipped 3D works by assigning different frames of the image to different
displays. The even frames are sent to the left display and the odd frames to the right
display as in Figure 20.
