3. Features & Operating Condition
3.1. Brief Description
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(bio-
microscopic examination of the eye)
3.2. Operating Condition
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
Page 15
-------------------------------------------------------------------------------------SLIT LAMP HS-5000 5X 15
!
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 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 re-
orienting or relocating the EUT.

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

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.
