Description
Otoscope. The device is suitable for use on both adults and children.
Ophthalmoscopes are intended for use only by physicians in hospitals and medical offices.

How to use
Inserting and removing batteries
Rotate the tool head counterclockwise to remove it from the handle. Insert two standard 1.5V AA (Mignon) alkaline batteries (IEC standard designation LR6) into the handle socket so that the positive terminals face the top of the handle.
Rotate the tool head clockwise on the handle. Turning On and Off: There is an on/off slide switch on the handle. Pushing the slide switch up turns the device on; pushing it down turns it off.
Place the selected speculum on the metal frame of the otoscope. Rotate the speculum to the right until you feel resistance. The size of the ear speculum is indicated on its back.
The swivel lens is attached to the device and can be rotated 360°.
If you want to introduce external instruments into the ear (e.g. tweezers), you need to rotate the swivel lens (approximately 3x magnification) located on the head of the otoscope by 180°.
Pneumatic otoscopy (= examination of the eardrum) requires a bulb, which is not included but can be ordered separately (see Spare Parts and Accessories). Take the metal connector, which is not included but can be ordered separately (see Spare Parts and Accessories), and insert it into the appropriate compartment on the side of the otoscope head. The bulb's tube is inserted onto the connector. Now you can carefully fill and introduce the required amount of air into the ear canal.

Warnings
Please note that the correct and safe functioning of our instruments is only guaranteed if both the instruments and their accessories come exclusively from Riester.
The use of other accessories may result in increased electromagnetic emissions or reduced electromagnetic immunity of the device and may lead to incorrect operation.
- If the instrument is used in the presence of flammable mixtures or mixtures of pharmaceutical products, there may be a risk of gas ignition.
- Tool heads and battery-powered handles must never be immersed in liquids.
- Exposure to intense light during a prolonged eye examination using an ophthalmoscope can damage the retina.
- The device and ear specula are not sterile. Do not use on damaged tissue.
- Use new or disinfected ear specula to limit the risk of cross-contamination.
- Disposal of used specula must be carried out in accordance with current medical practices or local regulations regarding the disposal of infectious and biological medical waste.
- Use only Riester accessories/consumables or those approved by Riester.
- Cleaning frequency and methods must comply with the facility's regulations for cleaning non-sterile devices. The cleaning and disinfection instructions specified in the instructions for use must be followed.
- The instrument may only be used by qualified personnel.
Use in MRI environments is prohibited.
There is a risk of gas ignition if the device is used in the presence of flammable mixtures or mixtures of pharmaceutical products and air, oxygen or nitrous oxide.
The device must not be used in rooms where flammable mixtures or mixtures of pharmaceutical products and air, oxygen or nitrous oxide are present, for example in operating rooms.
The device must be used in a controlled environment.
The device must not be exposed to extreme environmental conditions.
It is recommended to remove the (rechargeable) batteries from the handle before cleaning or disinfecting. When cleaning and disinfecting instruments, be careful not to allow liquids to penetrate the handle. Never place the instrument in liquids! Instruments with battery-powered handles are supplied non-sterile. Do not use ethylene, oxide gas, heat, autoclaves, or other methods that subject the material to excessive stress to sterilize the device. The devices are not suitable for reprocessing or machine sterilization. These procedures cause irreparable damage.
- If you will not be using the device for a long time or if you are taking it with you on a trip, remove the batteries from the handle.
- New batteries should be inserted when the instrument's light intensity becomes weak and could compromise the examination.
- For optimal light output, we recommend always using new, high-quality batteries when replacing the battery.
- Make sure that no liquid or moisture enters the handle.
Since prolonged exposure to bright light can damage the retina, use of the device for eye examination should not be unnecessarily prolonged and the light intensity set should not be higher than that necessary for a clear view of the structures being examined.
The retinal exposure dose that constitutes a photochemical hazard depends on the irradiance and the exposure time. If the irradiance value were halved, it would take twice as long to reach the maximum exposure limit.
Although no acute optical radiation risks have been identified with direct or indirect ophthalmoscopes, it is recommended that the intensity of light directed into the patient's eye be limited to the minimum level necessary for examination/diagnosis. Infants, children, aphakic individuals, or those with ophthalmic diseases will be at increased risk.
The risk may also increase if the patient has already been examined with the same instrument or any other ophthalmic instrument in the previous 24 hours. This is particularly true if the eye has been exposed to retinal photography.
The light emitted by the instrument is potentially harmful. The risk of ophthalmic damage is directly proportional to the duration of exposure. The standard risk level is exceeded when the duration of light irradiation from this instrument exceeds 5 minutes.
