    CBUS is a three wire serial interface between the main baseband components. The bus con- sists of data, clock and bus_enable signals. In NHL-10 the bus is connected from UPP_WD2 to UEM and the BT module. UPP_WD2 takes care of controlling the traffic on the bus.

    ‘blobs’. Sometimes they will be very hard to find, and thus the user probably will not notice them at all since they do no harm. But it is possible that a larger particle disturbs the user, causing the need for service. ISSUE 2 01/2004 COMPANY CONFIDENTIAL Copyright © 2003 Nokia. All Rights Reserved.

    The particles inside the cavity between window and lens have most probably been trapped there in assembly phase in Nokia factory. It is of course also possible that the user has disas- sembled the device and caused the problem. However, in most cases it should be possible to remove the particle(s) by using compressed air.
