1. Features The Digital Retinal Camera CX-1 is used to observe the retinas of patients’ eyes and take photographs of them. The camera has the following features. Both mydriatic and non-mydriatic modes in a single unit The CX-1 includes a mydriatic mode and non-mydriatic mode, and each mode can be selected with a single switch. In the mydriatic mode, the optical viewfinder is used for observation. In the non-mydriatic mode, the observation monitor on the special digital camera is used for observation.
2. Notes for Using the Instrument Digital camera • The digital camera installed on the Digital Retinal Camera CX-1 is designed for the CX-1. • The specifications differ from the typical commercially-available Canon digital cameras. It cannot be used for purposes other than observing and taking photographs of peoples’ eyes. Do not use the digital camera removing from the retinal camera body. This can damage or harm the performance of the instrument.
2. Notes for Using the Instrument • Never use disinfecting ethanol, glutaraldehyde or other solvents to clean the cover of the instrument, except the forehead rest and the chin rest. This could damage the cover of the instrument. • If the chin rest paper will not be used, be sure to disinfect the chin rest in the same way as the forehead rest whenever the patient changes.
