Possible Combinations with Other Equipment 
Only the peripheral devices listed in this chapter are approved for use with the ultrasound 
system. Any use of other devices with the system will be at the user's risk and may void the 
system warranty. 
On-board peripheral devices may need to be installed by an authorized Siemens representative 
or approved third party. Check with your sales representative. 
  WARNING: Accessory equipment connected to the analog and digital interfaces must be 
certified according to the respective EN and IEC standards (for example, EN 60950 and IEC 
60950 for data processing equipment and IEC 60601-1 for medical equipment). Anyone who 
connects additional equipment to any of the signal input or signal output ports configures a 
medical system and is therefore responsible that the system complies with the requirements of 
the system standards IEC 60601-1. Siemens can only guarantee the performance and safety of 
the devices listed in the Instructions for Use. If in doubt, consult the Siemens service department 
or your local Siemens representative. 
Leakage Currents 
Connecting peripheral products and accessories from non-isolated sources may result in 
chassis leakage current exceeding safe levels.
