USING THE SHEET MUSIC STAND

To easily view sheet music while playing your Concertmate-680, insert the
supplied sheet music stand into the holes on the top rear panel.

CONNECTING POWER

For portable use, you can power your Concertmate-680 using internal
batteries.  Using optional adapters, you can also power it from a standard
AC outlet or your vehicle's cigarette lighter socket.

NOTES:  Connecting an AC or DC adapter automatically disconnects internal
        batteries.

        Always disconnect an AC or DC adapter when you finish using the
        Concertmate-680.

USING BATTERIES

Your Concertmate-680 can use six AA batteries for power.  For the best
performance, we recommend alkaline batteries, such as Radio Shack Cat. No.
23-552.

CAUTION:  Only use fresh batteries of the requires size and type.

1.  Set MODE to POWER OFF.

2.  Press the tab on the battery compartment cover in the direction of the
    arrow, then pull up to remove the cover.

3.  Insert the batteries into the compartment as indicated by the polarity
    symbols (+ and -) marked beside the compartment.

4.  Replace the cover.

NOTES:  If you do not plan to use the Concertmate-680 with batteries for
        a week or more, remove the batteries.

        If the Concertmate-680 sounds weak or does not work properly,
        replace all six batteries.  Do not mix old and new batteries.

CAUTION:  Dispose of old batteries promptly and properly.

USING AC POWER

You can power your Concertmate-680 from a standard AC outlet using a 9-volt
AC adapter (not supplied), such as Radio Shack Cat. No. 273-1656.

CAUTIONS:  You must use an AC adapter that supplies 9 volts of DC power and
           delivers at least 600 milliamps.  Its center tip must be set to
           negative, and its plug must properly fit the Concertmate-680's
           DC 9V jack.  The recommended adapter meets these specifications.
           Using an adapter that does not meet theses specifications could
           damage the Concertmate-680 or the adapter.

           Always plug the AC adapter into the Concertmate-680 before you
           plug it into the AC outlet.  Always unplug the AC adapter from
           the AC outlet before you unplug it from the Concertmate-680.

1.  Set MODE to POWER OFF.

2.  Insert the AC adapter's barrel plug into the DC 9V jack on the rear of
    the Concertmate-680.

3.  Plug the adapter into a standard AC outlet.

USING VEHICLE BATTERY POWER

You can power your Concertmate-680 from your vehicle's cigarette-lighter
socket using a DC adapter (not supplied), such as Radio Shack Cat. No.
270-1562.

CAUTIONS:  The vehicle must have a 12-volt DC, negative-ground electrical
           system.  Most vehicles have this type of system, but we
           recommend that you contact the vehicle's dealer if you are
           unsure.  Using the adapter and Concertmate-680 with any other
           electrical system could damage the adapter, the Concertmate-680,
           or the vehicle's electrical system.

           You must use a DC adapter that supplies 9 volts of DC power and
           delivers at least 600 milliamps.  Its center tip must be set to
           negative, and its plug must properly fit the Concertmate-680's
           DC 9V jack.  The recommended adapter meets these specifications.
           Using an adapter that does not meet these specifications could
           damage the Concertmate-680 or the adapter.

           Always plug the DC adapter into the Concertmate-680 before you
           plug it into the cigarette lighter socket.  Always unplug the DC
           adapter from the cigarette lighter socket before you unplug it
           from the Concertmate-680.

1.  Set MODE to POWER OFF.

2.  Connect the adapter's blue-tipped barrel plug to the adapter's cord,
    matching TIP to negative (-).

3.  Set the adapter's voltage switch to 9 volts.

4.  Insert the adapter's barrel plug into the Concertmate-680's DC 9V jack.

5.  Plug the other end of the adapter into the vehicle's cigarette-lighter
    socket.
