    Precautions to consider when mounting the sounder

    Applicable Series
    PKM Series (PIN type)

    Secure the rear cover pins to the board.

    Failure to do this may result in a chattering type noise.

    How the failure occurs

    A vibration occurs when noise is generated causing the cover pins* to collide with the board repeatedly, which may result in the generation of a chattering type noise.
    A noise may also be generated as a result of the board striking other parts as well due the force of the collision being propagated throughout the board.

    • *Cover pins (plastic pins): Used to stabilize the product after it is mounted on the board.

    For reference

    Please secure the pins to the board in order to suppress chattering noises by using adhesive.

    In addition, securely fix the parts other than the sounder to the board.
