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.
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. Swivel lens for magnification
The swivel lens is fixed to the device and can be swivelled 360°.
4. Insertion of external instruments into the ear
If you wish to insert external instruments into the ear (e.g. twee-
zers), you have to rotate the swivel lens (approx. 3-fold magnifica-
tion) located on the otoscope head by 180°. Now you can use the
operation lens.
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 carefully insert the
necessary volume of air into the ear canal.
