ˆCare

To enjoy your mixer for a long time:

•Keep the mixer dry. If it gets wet, wipe it dry immediately.

•Use and store the mixer only in normal temperature environments.

•Handle the mixer gently and carefully. Do not drop it.

•Keep the mixer away from dust and dirt.

•Wipe the mixer with a damp cloth occa- sionally to keep it looking new.

Modifying or tampering with the mixer’s inter- nal components can cause a malfunction and might invalidate its warranty. If your mix- er is not performing as it should, take it to your local RadioShack store for assistance.

REPLACING THE FUSE

Your mixer requires a 250-volt, 0.5-amp fuse to protect it from power surges and short cir- cuits. If the mixer suddenly turns off or will not turn on, the fuse could be blown. Replace the fuse with a 0.5-amp, 250volt, fast-acting, 11/4 x 1/4 inch fuse (not supplied).

Follow these steps to replace the fuse.

1.Using a Phillips screwdriver, unscrew the fuse compartment cap on the back of the mixer.

2.Remove the old fuse and replace it with an identical fuse.

Caution: Never use a fuse of a different type or rating.

3.Replace the fuse compartment cap.

ˆTroubleshooting

We do not expect you to have any problems with your mixer, but if you have a problem, this in- formation might help. If the problem persists, take the mixer to your local RadioShack store for assistance.
