CAUTION

The FlexScan T1781 requires special precautions regarding EMC and need to be installed, put into

service and used according to the following information.

Do not use any cables other than the cables that provided or speci ed by us.

Using other cables may cause the increase of emission or decrease of immunity.

Cable Length: Max. 2m

Do not put any portable and mobile RF communications equipment close to the FlexScan T1781.

Doing so may affect the FlexScan T1781.

The FlexScan T1781 should not be used adjacent to or stacked with other equipment. If adjacent or

stacked use is necessary, the equipment or system should be observed to verify normal operation

in the con guration in which it will be used.

Anyone who connects additional equipment to the signal input part or signal output parts,

con guring a medical system, is responsible that the system complies with the requirements of IEC/

EN60601-1-2.
