    Repairs and testing are supported only at the complete board level. Respironics does not recommend component repair of the BiPAP Vision. The circuit boards in the BiPAP Vision are multilayer boards. Due to the very small trace size, extreme care must be used when replacing components to prevent permanent nonrepairable damage to the circuit board.
