This instrument has been tested and found to comply with the limits for medical devices to the IEC60601-1-2 and Medical Device Directive 93/42/EEC. These limits are intended to provide reasonable protection against harmful interference in a typical medical environment.

This instrument generates, uses and can radiate radio frequency energies and, if not put in service and used in accordance with the instructions, may cause harmful interference to other devices in the vicinity.

However, there is no guarantee that interference will not occur in a particular location.
If the system does cause harmful interference to other devices, which can be determined by turning the system off and on, try to eliminate the interference by adopting one or more of the following measures:

• reorient and/or relocate the receiving device;
• increase the distance between the devices;
• connect the system to an outlet on a different circuit than that to which the other devices is connected;
• consult the manufacturer or field service technician for help.

Essential performance: continuous operation (measurement status).
