Troubleshooting

Examples of retinal photograph

Possible cause

Dark shadow or bright reflection
appears at the top or bottom of the
image.

The instrument is positioned
too high to the patient’s eye.

The instrument is positioned
too low to the patient’s eye.

Dark shadow or bright reflection
appears at the left or right of the
image.

Peripheral area become whitened.

Perform all alignment steps to obtain a clear
retinal image with consistent brightness. Depending on the patient’s eye fixation condition, you may obtain a good image by locating
working dots away from the dot position aid.

The instrument is positioned
too right or left to the patient’s
eye.

Diopter compensation knob is
not in click.

Check that diopter compensation knob is in
the correct position by slowly moving the knob
to see if it cricks.

The instrument is positioned
too close to the patient’s eye.
The instrument is positioned
too far from the patient’s eye.

Locate the digital camera to the position
where working dots become smallest. When
flares still persist, pull the digital camera a
little or move the optical component to the
patient. (Working dots may be fades a little.)

The pupil diameter is small.

Turn exposure compensation knob to +1 or

transmitter manufacturer and d is the recommended separation distance in metres (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site surveya,
should be less than the compliance level in
each frequency rangeb.

At 80MHz and 800MHz, the higher frequency range applies.
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people.

Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios,
amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the
electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured
field strength in the location in which the KOWA nonmyd WX is used exceeds the applicable RF compliance level above, the
KOWA nonmyd WX should be observed to verify normal operation. f abnormal performance is observed, additional measures
may be necessary, such as reconfiguring or relocating the KOWA nonmyd WX
Over the frequency range 150kHz to 80MHz, field strengths should be less than 3 V/m.

Recommended separation distances between
portable and mobile RF communications instrument and KOWA nonmyd WX
KOWA nonmyd WX is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of KOWA nonmyd WX can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications instrument (transmitters) and KOWA nonmyd WX as recommended below, according to the
maximum output power of the communications instrument.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres (m) can
be estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1
80MHz and 800MHz, the separation distance for the higher frequency range applies.
NOTE 2
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people.
