Technical specifications:
230 V or 120 V version options

ATTENTION!

• If you do not use the device for a long time or take it with you while traveling, please remove the batteries and rechargeable batteries from the handle.
• New batteries should be inserted when the light intensity of the instrument becomes weaker.
• In order to obtain an optimal light yield, we recommend that you always insert new high-quality batteries when changing the battery (as described in 3.1 and 3.2).
• If there is a suspicion that liquid or condensation has penetrated the handle, it must not be charged under any circumstances.
• This can lead to a life-threatening electric shock, especially with regard to the socket handles.
• To extend the battery life, the battery should not be charged until the light intensity of the instrument becomes weaker.

Waste disposal:
Please note that batteries and rechargeable batteries must be disposed of as special waste. You can obtain the relevant information from your local authority or from your local environmental advisor.

Fitting instrument heads

Fit the required instrument head on the receptacle on the upper part of the handle such that the two recesses of the lower part of the instrument head fit on the two protruding guide studs on the battery handle. Press the instrument head lightly onto the battery handle and screw the handle clockwise as far as it goes. The head is removed by screwing it counterclockwise.

Switching Type C and AA battery handles on and off
Activate the instrument by turning the switching ring on the top of the handle clockwise direction. To switch off the instrument turn the ring anti-clockwise direction until the device is switched off.

rheotronic® for adjusting the light intensity
With the rhetoric, it is possible to modulate the light intensity for the C and AA handles. Depending on how often you turn the switching ring clockwise or anti-clockwise direction, the light intensity is stronger or weaker.

ATTENTION!
At every switch-on of the battery handle the light intensity is at 100% Automatic safety switch-off after 180 seconds.

Observe the Operating Instructions!

ri-scope®L otoscope

Purpose
The Riester otoscope described in these Operating Instructions is produced for illumination and examination of the auditory canal in combination with the Riester ear specula.

Fitting and removing ear specula
Either Riester disposable ear specula (blue colour) or reusable Riester ear specula (black colour) can be fitted to the otoscope head. The size of the ear specula is marked at the back of the speculum.

L1 and L2 otoscopes
Screw the speculum clockwise until noticeable resistance is felt. To remove the speculum, screw the speculum counterclockwise.

L3 otoscope
Fit the chosen speculum on the chrome-plated metal fixture of the otoscope until it locks into place. To remove the speculum, press the blue ejection button. The speculum is automatically ejected.

Swivel lens for magnification
The swivel lens is fixed to the device and can be swivelled 360°.

Insertion of external instruments into the ear
If you wish to insert external instruments into the ear (e.g. tweezers), you have to rotate the swivel lens (approx. 3-fold magnification) located on the otoscope head by 180°. Now you can use the operation lens.

Pneumatic test
To perform the pneumatic test (= examination of the eardrum), you require a ball, which is not included in the normal delivery package but can be ordered separately. The tube for the ball is attached to the connector. Now you can carefully insert the necessary volume of air into the ear canal.

Technical data of the lamp

• Otoscope XL 2.5 V 2.5 V 750 mA ave. life 15 h
• Otoscope XL 3.5 V 3.5 V 720 mA ave. life 15 h
• Otoscope LED 2.5 V 2.5 V 280 mA ave. life 10.000 h

ri-scope L ophthalmoscopes

Purpose/indication
The Riester ophthalmoscope described in these Operating Instructions is produced for the examination of the eye and the eye ground.

ATTENTION!
Because prolonged intense exposure to light can damage the retina, the use of the eye exam device should not be unnecessarily prolonged, and the brightness setting should not be set higher than needed for a clear representation of the target structures. The irradiation dose of the photochemical exposure to the retina is the product of irradiance and duration of irradiation. If the irradiance is reduced by half, the irradiation time may be twice as long to reach the maximum limit.

Although no acute optical radiation hazards have been identified for direct or indirect ophthalmoscopes, it is recommended that the intensity of light directed into the patient‘s eye be reduced to the minimum required for examination/diagnosis. Infants/children, aphasics, and people with eye diseases are at a higher risk. The risk may be increased if the patient has already been examined with this or another ophthalmological instrument during the last 24 hours. This is especially true when the eye has been exposed to retinal photography.

The light of this instrument may be harmful. The risk of eye damage increases with the duration of irradiation. An irradiation period with this instrument at the maximum intensity of longer than >5 min. exceeds the guideline value for hazards. This instrument does not pose a photobiological hazard according to DIN EN 62471 but still features a safety shutdown after 2 / 3 minutes.

Lens wheel with correction lens
The correction lens can be adjusted on the lens wheel. The following correction lenses are available:

L1 and L2 ophthalmoscopes

• Plus: 1-10, 12, 15, 20, 40.
• Minus: 1-10, 15, 20, 25, 30, 35.

L3 ophthalmoscope

• Plus: 1-45 in single steps
• Minus: 1-44 in single steps

The values can be read off in the illuminated field of view. Plus values are displayed in green numbers, minus values with red numbers.

Apertures
The following apertures can be selected with the aperture hand wheel:

L1 ophthalmoscope
A semi-circle, small/medium/large circular aperture, fixation star, slit.

L2 ophthalmoscope
A semi-circle, small/medium/large circular aperture, fixation star and slit.

L3 ophthalmoscope
A semi-circle, small/medium/large circular aperture, fixation star, slit, and grid.

Aperture/Function

• Semicircle: for examinations with turbid lenses
• Small circle: to reduce reflections for small pupils
• Medium circle: to reduce reflections for small pupils
• Large circle: for normal examination results
• Grid: for topographic determination of retina changes
• Light slit: to determine differences in the level
• Fixation star: to ascertain the central of eccentric fixation

Filters
Using the filter wheel, the following filters can be switched for each aperture:

• L1 ophthalmoscope Red-free filter
• L2 ophthalmoscope Red-free filter, blue filter and polarisation filter.
• L3 ophthalmoscope Red-free filter, blue filter and polarisation filter.

Filter/Function

• Red-free filter: contrast enhancing to assess fine vascular changes, e.g. retinal bleeding
• Polarisation filter: for precise assessment of tissue colours and to avoid retinal reflections
• Blue filter: for improved recognition of vascular abnormalities or bleeding, for fluorescence ophthalmology

For L2 + L3, every filter can be switched to every aperture.

Focusing device (only with L3)
Fast fine adjustment of the examination area to be observed is achieved from various distances by turning the focussing wheel.

Base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM broadcasting and television broadcasting can not be predicted theoretically accurately. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic examination should be considered. If the measured field strength at the location where the ri-­‐ scope L is used exceeds the above RF compliance level, the ri-­‐scope L should be observed to verify normal operation. If abnormal performance is observed, additional measures may be required, such as reorienting or shifting the ri-­‐scope L

The ri-­scope L is intended for use in an electromagnetic environment in which RF emissions are controlled. The customer or user of the ri-­scope L can help to avoid electromagnetic interference by observing the minimum distance between portable and mobile RF communications equipment (transmitters) and the ri-­scope L in accordance with the maximum output power of the communication equipment.
