produced for illumination and examination of the auditory canal in combination with
the ear specula. The ADC
® Diagnostix™ Otoscopes are compatible with Riester, or

The ADC
® Diagnostix Otoscope is fitted with an adapter for use with Welch Allyn
specula. If different specula are being used, the adapter should be removed by

resistance is felt. To remove the speculum, twist the speculum counter-clockwise.
6.3 Swivel Lens for Magnification
The swivel lens (3x max.) is fixed to the device and can be
swiveled 360°.
6.4 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 located on the otoscope head by 180°.
6.5 Pneumatic Test
To perform the pneumatic test (examination of the eardrum), an
insufflator is required to be connected (sold separately (#5122N).
The tube for the insufflator is attached to the connector port on
the right side of the instrument head. Now you can carefully
insert the necessary volume of air into the ear canal.
