INSTRUCTION MANUAL
RETINAL CAMERA
TRC-50DX
INTRODUCTION Thank you for purchasing the TOPCON TRC-50DX Retinal Camera. This instrument is used to observe, take pictures or record pictures of the posterior segment of the eye through the pupil. In Type IA of this instrument, the fluorescein angiography with indocyanine green is possible. This instrument has the following features: • This instrument assists the user in obtaining pictures of exceptional and stable quality. • The instrument is easier to use and operate than previous models. • A wide variety of optional accessories are available for diverse photographic and imaging purposes. This manual outlines the TRC-50DX Retinal Camera, including operating procedures, troubleshooting, maintenance and cleaning. Before using the instrument, carefully read the "DISPLAY FOR SAFE USE" and the "SAFETY CAUTIONS" to familiarize yourself with the features of the TRC-50DX Retinal Camera and to ensure that you operate it in an efficient and safe manner. Always keep this Instruction Manual at hand.
[Warning] Be careful not to bump the patient’s eyes or nose with the instrument during operation. [The patient may be injured.] This symbol is applicable for EU member countries only. To avoid potential negative consequences for the environment and possibly human health, this instrument should be disposed of (i) for EU member countries - in accordance with WEEE (Directive on Waste Electrical and Electronic Equipment), or (ii) for all other countries, in accordance with local disposal and recycling laws.
CAUTIONS FOR USE Basic caution When taking a picture, make sure that the patient keeps his/her hands away from the movable parts to avoid possible injury. Disposal When disposing of TRC-50DX parts, follow the local regulations for disposal and recycling. "Because prolonged intense light exposure can damage the retina, the use of the device for ocular examination should not be unnecessarily prolonged, and the brightness setting should not exceed what is needed to provide clear visualization of the target structures. This device should be used with filters that eliminate UV radiation (<400nm) and, whenever possible, filters that eliminate short-wavelength blue light (<420nm).
1
The retinal exposure dose for a photochemical hazard is a product of the radiance and the exposure time. If the value of radiance were reduced in half, twice the time would be needed to reach the maximum exposure limit. While no acute optical radiation hazards have been identified for fundus cameras, it is recommended that the intensity of light directed into the patient's eye be limited to the minimum level which is necessary for diagnosis. Infants, aphakes and persons with diseased eyes will be at greater risk. The risk may also be increased if the person being examined has had any exposure with the same instrument or any other ophthalmic instrument using a visible light source during the previous 24 hours. This will apply particularly if the eye has been exposed to retinal photography." "Caution: Federal laws restricts this device to the sale by or on the order of a physician."
ENVIRONMENTAL CONDITIONS FOR USE Temperature: 10°C ~ 40°C Humidity: 30% ~ 75% (Non-condensing) Air pressure: 700hPa ~ 1060hPa

When storing the instrument, ensure that the following conditions are met: (1) The instrument must not be splashed with water. (2) Store the instrument away from environments where air pressure, temperature, humidity, ventilation, sunlight, dust, salty/sulfurous air, etc. could cause damage. (3) Do not store or transport the instrument on a slanted or uneven surface or in an area where it is subject to vibrations or instability. (4) Do not store the instrument where chemicals are stored or gas is generated. 3. Normal life span of the instrument: 8 years from delivery providing regular maintenance is performed [TOPCON data]
ENVIRONMENTAL CONDITIONS FOR PACKAGING IN TRANSPORTATION Temperature: -20°C ~ 50°C Humidity: 10% ~ 95%
CHECKPOINTS FOR MAINTENANCE 1. Periodically inspect the instrument and its parts. 2. Before using the instrument after a long period of inactivity, make sure that it operates safely and normally. 3. Be careful not to stain the objective lens with fingerprints, dirt, etc., as this will affect the coatings and quality of pictures that the instrument takes. 4. When the instrument is not in use, cap the objective lens and cover the instrument with the dust cover. 5. If the objective lens is stained, clean it according to "CLEANING THE OBJECTIVE LENS" on page 58 of this manual.
