stops. The head is removed by turning it anti-clockwise. Two types of operation
are possible:
a) Quick expansion
Push the set screw on the instrument head down with your thumb. In this ad-

b) Individual expansion
Turn the adjusting screw clockwise until you reach the desired expansion width.
The shanks close again when the screw is turned anticlockwise.
11.3. Swivel lens
On the nasal speculum there is a swivel lens with a magnification of around
2.5x, which can simply be pulled out or reinserted into the opening provided on
the nasal speculum, as required.
