Precautions
This device is designed and manufactured for use in
medical purposes. Do not use the device for any other
purpose.
Precautions for safe operation
• Some people may experience discomfort (such as eye
strain, fatigue, or nausea) while watching video images.
Sony recommends that all viewers take regular breaks
while watching video images. The length and frequency
of necessary breaks will vary from person to person. You
must decide what works best. If you experience any
discomfort, you should stop watching the video images
until the discomfort ends; consult a doctor if you believe
necessary.
• Avoid wearing the unit in environments where your head
may shake, or while you are walking or performing
exercise, because there is a higher possibility that you
experience discomfort.
• If you intend to connect the unit to other medical
equipment, be sure to read the “Precautions when
connected to other medical equipment” section.
Precautions when connected to
other medical equipment
– Before you utilize this device and/or connect this device
to any other medical device, please be aware of and
abide by the following precautions:
(a) Before actually using this device for medical
practice, please check and confirm that you do not
experience any discomfort in your use that could be
disruptive or impeditive in conducting your intended
activity or medical practice.
(b) If you experience or are likely to experience such
discomfort, please refrain from using this device.
(c) Generally, discomfort (such as eye strain, fatigue,
nausea, or motion sickness) can be provoked by such
factors as quick movements or shakiness of video
picture, focal position of video pictures, distance
between objects and image capturing modules, user’s
point of gaze in video pictures, other varying
conditions of video pictures to be input to this device,
and individual user’s health conditions.
Preparing for unforeseen
circumstances
Be prepared for unforeseen circumstances by using a
stationary monitor, for example, in conjunction with this
unit. In addition, prepare a backup unit if necessary.
Attaching the head mounted monitor
before use
Before using the unit in an actual medical procedure,
attach the head mounted monitor in the same time frame
envisioned for the medical procedure and check that none
of the following problems occur.
• Check that there is no discomfort (fatigue due to head
pain, pressure, or weight) that interferes with the medical
procedure.
Any head discomfort may be alleviated if the head
mounted monitor is attached correctly. For details read
“Mounting the Head Mounted Monitor” (page 21) when
attaching the unit. If you experience any discomfort that
interferes with the medical procedure, do not use the
unit.
• Check that the head mounted monitor does not shift
positions repeatedly.
This may be alleviated if the head mounted monitor is
attached correctly. For details read “Mounting the Head
Mounted Monitor” (page 21) when attaching the unit. If
the position of the head mounted monitor shifts during a
medical procedure, correct the error by referring to
“Correcting Displacement” (page 25).
If the head mounted monitor shifts repeatedly, cease
using the unit.
• Check before use that there is no rash or itching due to
allergies or other problem caused by contact with the
pads on the head mounted monitor. If you experience any
rash or itching that interferes with the medical
procedure, do not use the unit.
• Make sure to finish all setup before using the unit in a
medical procedure.
• If the head mounted monitor does not match your head
size, do not use the unit.
Use with electrosurgical knives and
similar devices
If this unit is used together with an electrosurgical knife,
etc., the picture may be disturbed, warped or otherwise
abnormal as a result of strong radio waves or voltages from
the device. This is not a malfunction.
When you use this unit simultaneously with a device from
which strong radio waves or voltages are emitted, confirm
the effect of this before using such devices, and install this
unit in a way that minimizes the effect of radio wave
interference.
Preliminary connection testing
Connect the unit to any medical devices you intend to use
and verify correct operation before using the unit and the
devices in an actual medical procedure.
