Care

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,

 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.

Troubleshooting

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.

Problem

Possible Solution

The mixer does not work.

Check the AC power connection and make sure the AC outlet is 
“live.”

Check the power connection to the rest of the system (amplifier/
receiver, input sources, and so on).

Check the fuse. See “Replacing the Fuse” on Page 14.

No signal from an audio input 
sources.

Make sure the TALKOVER switch is set to OFF.

Check the mixer’s and the source’s control settings.

Check the connection between the mixer and the input source.

You are getting a hum from the 
PHONO sources.

Make sure the turntable’s ground wire (usually black or green) is 
connected to the GND screw on the back of the mixer.
