Glasstron is a brand-new concept in
visual display
Note on the LCD (Liquid Crystal
Display)
The LCD screen is made with high-
precision technology. However, black
points or bright points of light (red, blue,
or green) may appear constantly on the
LCD screen. This is not malfunction.
(Effective dots: more than 99.99%)
Congratulations on your purchase of a Sony
Glasstron Personal Viewer. The Glasstron,
using current technology in small,
lightweight visual displays, provides a
television viewing experience similar to
watching a 52-inch television from a
distance of approximately 6.6 feet (2 m).
(Viewing experience may differ according
to individual perception.)
The Glasstron Personal Viewer creates an
image through two separate liquid crystal
displays, in close proximity to your eyes.
To insure your safe use of the Glasstron,
please become familiar with its basic
operations, including proper fitting
instructions, and be aware of any symptoms
of eye fatigue or other discomfort you may
experience.
WARNING
YOUR FAILURE TO FOLLOW THESE
OPERATING INSTRUCTIONS MAY
RESULT IN EYE FATIGUE, EYE
IMPAIRMENT, OR OTHER EYE INJURY,
PROPERTY DAMAGE OR DEATH.
WARNING
THIS PRODUCT SHOULD NOT BE USED
BY CHILDREN AGE 15 OR YOUNGER.
THE EYES OF CHILDREN ARE STILL
DEVELOPING AND MAY BE ADVERSELY
AFFECTED FROM USE OF THIS
PRODUCT.

About the Glasstron
Display unit
The display unit is equipped with two
small (left and right) LCDs.
Power supply box
You can use Sony's recommended
optional battery pack. You can also use
the house current. To use the Glasstron,
connect your video equipment to A/V
IN on the power supply box.
Features
· A powerful, big screen experience
comparable to watching a 52-inch screen
from approximately 6.6 feet (2 m) away.
· Handy portable folding display.
· The display unit weighs only 3.4 oz (95g).
· Approximate continuous use for up to
seven hours with Sony's recommended
battery pack, NP-F550.
Caution: The screen is always right in front of you.
The Glasstron is a face-mounted display. With this type of display, the screen is always in front
of you, even if you move your head. Because of this feature, you can concentrate on the screen
more easily compared with ordinary TVs, and you have a sense of being in the action.
· It is easy to adjust the Glasstron to your eyes. You can use the display unit even while
wearing glasses.
· Every time you use the Glasstron, the adjustment screen appears to help you adjust the
display unit properly. You can also check whether the left and right screen positions are
properly aligned or not.
· If you keep using the Glasstron continuously for three hours, a warning appears on the screen
and the power will turn off automatically.
The Glasstron consists of the following items:

Notes
· Even if you use the supplied audio/video

carried to the Glasstron depending on the
video source. In this case, contact your Sony
dealer or local authorized Sony service
facility.
· When you connect the Glasstron to the audio
output jacks (phono jacks) of your video
equipment, connect the Glasstron to both the
right and left audio output jacks. If you
connect the Glasstron to just one audio output
jack, you will hear sound from only one of the
stereo earphones.
