The Video Rhino Laryngoscope should be connected as follows. See also figure 1. Plug the power
supply unit into a mains socket (100 - 240 V AC, 50 - 60 Hz). The secondary connection of the power
supply unit must be plugged into the connector into which the video cable for the monitor is also
plugged.
Then the connection cable must be plugged into the light guide plug and this in turn must be inserted
into the cold light source.
An external monitor for displaying the video signal is connected to the Video Out connector, then the
image captured by the camera appears on the screen.
Now the Video Rhino Laryngoscope can be used for its intended purpose, the green LED on the light
guide plug is lit.
Caution:
Monitor and light source must meet the requirements of the DIN EN 60601 standard!

Insert, angle and retract the insertion tube.
Carefully insert the insertion tube into the corresponding regions to be examined (nasal and pharyn-
geal cavities). If necessary, the distal end can be adjusted by 130°
with the adjustment lever (see fig-
ure 3). The level of adjustment should be tested in a free trial. The examining doctor holds the laryngo-
scope in his hand to check the adjustment of the distal end and observes the image on the screen.
After the examination, return the control lever to the rest position and carefully withdraw the insertion
tube.
