1.Intended use
The used symbols have the following meaning:
Warnings are identified by this Attention symbol.
Tips & tricks are identified by this light bulb icon.
Only the included medical power adapter GSM36B12-P1J may be
connected to the device for power supply.
The Plusoptix Vision Screener is used for the early detection of vision disorders (preventive
eye care). These vision disorders can cause permanent loss of vision (amblyopia) if they are
not detected and treated in the early years of a child’s life.
To detect vision disorders, the Plusoptix Vision Screener measures the sphere, cylinder,
axis, line of vision and pupil size of both eyes at the same time. Using these measurement
values, the spherical equivalent, gaze symmetry and interpupillary distance are calculated.
All measurement values are compared with age-based referral criteria. “Refer” is
automatically displayed as a precautionary result for every patient requiring an
ophthalmologist appointment.
Note:
False-positive and false-negative results can occur in any type of preventive
examination.
Note:
Preventive eye care with the Plusoptix Vision Screener does not replace the eye
examination carried out by an eye care professional. An eye care professional
remains the only person qualified to interpret the measurement values and
establish a diagnosis. The measurement values must not be used directly to
prescribe glasses or contact lenses.
All patients who are not already being treated by an eye care professional should undergo a
preventive eye care examination. The first preventive eye care examination should be
performed before the child's first birthday. In the event of a family history of visual disorders,
an earlier preventive eye care examination at ages between 5 and 8 months is
recommended. The examination should then be repeated regularly, as the eyes can change
during growth and new visual disorders can manifest at any time.

2.Responsibility of the operator
The operator is responsible for ensuring that only trained users work with the Plusoptix
Vision Screener.
Training
Training must at least include reading the user manual and a briefing on the operation of the
device. The briefing on the operation of the device is provided by Plusoptix, by Plusoptix
authorised dealers, or can be carried out by a previously trained user.
Electrical safety and electromagnetic compatibility
The operator is responsible for ensuring that external equipment connected to the device
meets the standards IEC 60601-1 and IEC 60601-1-2 in respect to electrical safety and
electromagnetic compatibility together with the equipment.
Attention:
The device may not be opened. Opening the device runs the risk of receiving an
(invisible) electric shock, and it will invalidate its approval as a medical device.
The operator is responsible for ensuring that the device is sent to Plusoptix or an
authorised Plusoptix dealer for service or warranty cases.
Attention (only S12C):
If you insert batteries other than the supplied rechargeable batteries, only use
rechargeable Nickel Metal Hydride NiMH/AA HR6 batteries with a capacity of
1,900 to 2,100 mAh and a quick-charge rate of at least 1 A. When inserting the
batteries, check for the correct polarity.
In accordance with Standard IEC 60601-1-2, we are required to provide the following
warnings:
Attention:
The use of accessories, transducers and cables that have not been approved or
provided by the manufacturer may result in increased electromagnetic emission
or reduced electromagnetic immunity of the device resulting in faulty operation.
Attention:
Avoid use of the device next to or in conjunction with other equipment, as this
could result in faulty operation. If such a use is required, the devices should be
monitored to ensure correct function.

3.2. The home screen
After the start up, you will see the start screen. Similarly to all the screen displays of the
device, it has the following structure: the header is arranged at the top, the information part in
the middle, and the navigation bar at the bottom.

4.Starting a measurement and aligning the device
- Select an age group by touching the appropriate age range on the time bar. You must
select the age group in order to ensure that the measurement values of the patient are
compared with the correct age-specific referral criteria.
- Hold the device at eye level to the patient, about 1.2 meters away. The measuring
distance is one meter, but it requires practice to correctly estimate this measuring
distance. It is easier to hold the device further away when starting the measurement and
then slowly move it towards the patient.

- Press the shutter on the handle or touch the flashing “GO” button (1) on the screen to start
the measurement; you will hear a warble sound. Instead of the start screen, you will now
see the camera image.
Note:
Touch the camera image if you wish to discontinue a started measurement.
Note:
The screen of the plusoptiX S12C is fixed at a 45° angle to the camera axis. Tilt
your wrists downwards to align the device.
- Align the device so that both eyes can be seen on the screen, and then slowly move the
device towards the patient until the camera image can be seen in high-definition on the
screen (individual hairs of the eyebrows and the eyelashes must be visible).
Note:
If a patient is not looking at the nose of the smiley face during the measurement,
this can cause a termination of the measurement. The nose and the knees of the
patient must always be directed towards the device.

- The end of the measurement is confirmed by a “PING” sound. After the measurement,
you will first see the “camera image” results page.
- Touch the appropriate icon in the middle of the navigation bar to access each of the three
results pages:
Note:
Tap the camera image to zoom into the pupils. This
allows you to accurately examine the pupils for
media opacities and abnormal reflexes (Bruckner or
red reflex test).
In addition to the measurement values, a screening result is displayed:
The measurement has been successfully completed and the “Refer”
or “Pass” screening result is displayed. “Refer” is automatically
displayed as a preAttentionary result for every patient requiring an
eye care professional appointment.
The measurement concluded without result and a “Try again” or
“Refer or Try again” status is displayed. In this case, check the
measuring environment (see picture 2).
Was the measurement discontinued due to direct sunlight, an
incorrect measuring distance or a too small or too large pupil size?
For more information on measurements without result, refer to Short
Manual 10.
For more information on performing a measurement and on viewing as well as documenting
the measurement results, refer to Short Manuals 3 to 7.

degradation of the performance of this equipment could result.
Recommended safety distances between portable and mobile RF telecommunication devices and the device
The device is intended for use in an electromagnetic environment with controlled HF disturbance variables. The customer or user
of the device can contribute to avoiding electromagnetic disturbances by complying with the minimum distance between portable
and mobile HF telecommunication devices (transmitters) and the device – depending on the output power of the communication
device, as stated below.

For transmitters, whose maximum nominal output is not stated in the above table, the recommended safety distance in meters
(m) can be calculated using the equation from the relevant column, wherein P equals the maximum nominal output of the
transmitter in watts (W) as per information by the transmitter’s manufacturer.
COMMENT 1 At 80 MHz and 800 MHz, the higher frequency range applies.
COMMENT 2 These guidelines may not be applicable in all cases. Electromagnetic propagation is affected by absorption and
