L otoscope
3.1. Purpose
The Riester otoscope described in these Operating Instructions is produced for
illumination and examination of the auditory canal in combination with Riester
ear specula.
3.2 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 counter clockwise.
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.
3.3. Swivel lens for magnification
The swivel lens is fixed to the device and can be swivelled 360°.
3.4. 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.
3.5. 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 care-
fully insert the necessary volume of air into the ear canal.
