Features & Operating Condition

The device works like all slit lamps:

- stereomicroscopic examination of the eye under the slit light.

- microscopic examination of the ocular fundus and posterior vitreous body (using hubry’s lens).

These devices are designed for use by ophthalmologists and optometrists(within the realms of their respective professions) for specific diagnostic procedures(biomicroscopic examination of the eye) z As long as the slit lamp is in its original package it can be exposed to the following environmental conditions for up to 15 weeks for shipping and storage

- without risk of damage:

Temperature range : from –10˚C to +40˚C;

- Relative humidity range: from 30% to75%; z The device is made to operate under the following environmental conditions:

- Temperature range : from +10˚C to +40˚C;

- Relative humidity range: from 30% to 75%;

The device neither generates nor receives electromagnetic interference when used near other equipment. Therefore, no preventive or corrective measures are required

-------------------------------------------------------------------------------------SLIT LAMP

HS-5000 5X 15

!

CAUTION

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).

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 slit lamps, 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 increased of 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

Field strengths from fixed RF transmitters, as deter-mined by an electromagnetic site survey, a should be less than the compliance level in each frequency range. b

Interference may occur in the vicinity of equipment marked with the following symbol :

NOTE 1) At 80MHz and 800MHz, 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. a

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 EUT is used exceeds the applicable RF compliance level above, the EUT should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the EUT. b

Over the frequency range 150kHz to 80MHz, field strengths should be less than

11.4. Recommended separation distances between portable and mobile RF communications equipment and the EUT

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

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) At 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.
