Balance System SD Configuration 

Use Balance System SD Configuration to configure the system in detail (Refer to Configuring the 
System for general information about this screen). This section describes how to edit clinical 
codes and facility information and create custom protocols. 

Change Sensory Integration Defaults 

The normative data in both sensory integration tests (mCTSIB and BESS) can be specified to 
each facility’s needs (see Figure 7.10). Only mCTSIB default data is provided. Users must enter 
their own default BESS normative data.
