A method for operating a mobile device to set a voicemail password directly from the mobile device includes providing the mobile device with a memory for storing a visual voicemail application, an interface for receiving user input to the VVM application, and a transceiver for communication with a VVM system. The circuit board is provided in the housing, and includes a first surface and a first conductor on the first surface. The invention mainly points to application in the domain of biochips and microarrays, used in diagnostics, genetics and molecular studies. A resilient latch mounts to the frame and selectively engages the pin to hold the motor cover in the closed position.
