Introduction
Features
The Canon Digital Retinal Camera CR-2 takes digital photographic retinal images of patient’s eyes
across an angle of view of 45 degrees, in a naturally dilated state without using mydriatics. The CR-2
has the following features:
Reduced flash intensity
The CR-2 can take images at ISO 800/1600 at the standard flash intensity, and ISO 3200/6400 in low
flash intensity mode. This reduces patient discomfort caused by light glare.
Compact, user-friendly design
The CR-2 is designed to be even smaller, more lightweight and compact than the previous model.
This makes it easier to assist patients and provides significant ease of operation.
An operation lever has the integrated functions: vertical movement of the main unit, switching
between anterior segment and fundus, and manual focusing. This lever significantly improves
alignment operability.
Special digital camera
The CR-2 is equipped with a special digital camera using EOS digital technology. This enables the
CR-2 to fully maximize Canon technology for shooting high-quality, high-resolution diagnostic images.
Small pupil photography function
The CR-2 captures retinal images through pupils of the normal diameters from 4.0 mm. This small
pupil photography function permits image to be captured through pupils from 3.3 mm in diameters.
System optimized for digital photography
With the supplied imaging control software, the photographed images can be browsed, processed,
stored, output to the DICOM storage server, exported in DICOM or JPEG format and output to a
printer.
In this manual, the operation procedure is described with the Retinal imaging control software NM 2
(referred to as “Rics NM 2” ).
Indications for Use
For USA
The device is intended to be used for taking digital images of the retina of the human eye without a
mydriatic.
For European Union
This medical device is intended to observe and record images of retinal fundus through the pupil
without making contact with subject’s eye for the purpose of diagnosis by way of producing fundus
image information.

Electromagnetic Environment – Guidance
The CR-2 uses RF energy only for its internal
function. Therefore, its RF emissions are very low
and are not likely to cause any interference in nearby
electromagnetic equipment.
The CR-2 is suitable for use in all establishments,
including domestic establishments and those directly
connected to the public low-voltage power supply
network that supplies buildings used for domestic
purposes.
* Not applicable to regions where the rated voltage is less than 220 V.

Field strengths from fixed RF transmitters,
as determined by an electromagnetic site
surveya, should be less than the compliance
level in each frequency rangeb.
Interference may occur in the vicinity of
equipment marked with the following symbol:
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and

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 CR-2 is used exceeds the applicable RF compliance level
above, the CR-2 should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the CR-2.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
