    This article explains how to set up and connect the bass unit (subwoofer) to the Twentieth Anniversary Macintosh computer.

DISCUSSION

    Follow these steps to properly set up the bass unit on the Twentieth Anniversary Macintosh.

    The steps include:

    - Positioning the bass unit
    - Attaching the bass unit to the computer
    - Plugging in the power cord

    Positioning the bass unit

    Place the bass unit near a grounded outlet, within six feet of the computer. the bass unit is designed to be placed under your work surface and will perform best acoustically when placed on the floor. It can also be placed on any stable, flat surface.

    Caution: The bass unit contains a very strong magnet. To prevent the magnet from interfering with the computer's screen, do not place the bass unit next to the computer. Do not place floppy disks on top of the bass unit (data may be lost).


    Attaching the bass unit to the computer

    Follow these steps to attach the bass unit to the computer:

    Step 1
    Locate the large cable attached to the computer. This cable plugs into the bass unit.

    Step 2
    Locate the recessed well on the underside of the bass unit, and the groove containing a short cable already attached to the bass unit.

    Note: The recessed well also contains the bass unit's level control. The control is preset at the level that is appropriate in an average size carpete room. Note the location of the control in case you want to adjust it after you start up the computer

    Step 3
    Loosen the short cable from the groove.

    Step 4
    Plug the connector at the end of the computer's cable into the subwoffer's connector. Align the two connectors and press them together. Do not force the connectors.

    Note: The connectors are keyed so that they will only fit together one way. Rotate the connectors around until the small internal ribs and groovers on the connectors line up. You will then be able to push the two connectors together.

    Step 5
    Secure the connection by firmly rotating the metal band until you hear a click.

    Step 6
    Press the bass unit cable back into the groove.


    Plugging in the power cord

    Follow these steps to plug your equipment into a wall outlet:

    Step 1
    Make sure the voltage switch inside the well on the bottom of the bass unit is set for the voltage you connect to.

    The voltage switch is preset in the factory to the correct voltage for the area where you bought the computer.

    If there is any chance that the setting has been changed, or if you take the computer to a country with a different voltage system, it is important to check the voltage and change the setting if necessary. The voltage switch must be set correctly to avoid damaging your computer.

    Step 2
    Plug the socket end of the power cord into the recessed power plug inside the well on the bottom of the bass unit.

    Step 3
    Plug the other end of the power cord into a three-hole grounded outlet or power strip.

    Important: The only way to disconnect power completely is to unplug the power cord. Make sure the power cord is within easy reach so that you can unplug the computer when you need to.

    Step 4
    Turn the bass unit right side up.

    You can store any extra length of the power cord in the well.
