Do I need a special light source?
An LED light source (ATMOS LS 21 LED) for plugging onto an endoscope’s inlet for the fiber optic light cable is included in the scope of delivery. The light source is plugged into the ATMOS Strobo 21 LED itself and requires no other power supply. The stroboscope can also be used to control ATMOS light sources with fiber optic light cables. This requires a special connection cable.
Is the ATMOS Strobo 21 LED compatible with my endoscopes?
The light source included with the device has a standard adapter that fits all common endoscope models (Storz, Wolf, etc.). Further adapters for other endoscope models are available.
How do I record the patient’s voice?
An airborne sound microphone is included in the scope of delivery. It can be plugged onto the endoscope and is directed toward the patient. A body sound microphone adapter is available as an accessory.
