***Important: The circuit is offered without warranty and Delta is unable to accept any liability for
direct or consequential loss associated with their use. 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.***
