It is therefore important for designers to ensure that their Bluetooth handphone design is properly evaluated in a Design Verification Test. The results of the Design Verification Test should be used to assess the suitability of the handphone for manufacture.*** Data Sheet 9 GND May 19, 2005 Proprietary Information and Specifications are Subject to Change Preliminary DLBM-CH122 9.
