Battery Notes  
Dispose of old batteries promptly and properly.  
Do not burn or bury batteries.  
A sudden high output from the mixer could damage audio  
devices connected to the mixer and could damage your  
hearing, especially if you use headphones.  
If you connect an audio device and a microphone so they  
are output to the same channel, the signals from both  
devices are mixed and controlled by the mixer.  
Use only a fresh battery of the required size and recommended  
type.  
If you do not plan to use the mixer for more than a week,  
remove the battery. It can leak chemicals that can damage  
electronic parts.  
Presetting Audio Devices  
Make sure you power off the devices before you connect  
them to the mixer.  
Output  
To play the mixers output through your speaker system (at  
parties, dances, conferences, etc.), use an audio patch cord  
(not supplied) to connect the mixers OUTPUT L and R jacks  
to your receiver or amplifiers line input jacks.  
To record the mixers output, use an audio patch cord (not  
supplied) to connect the mixers OUTPUT L and R jacks to  
your recording devices line input jacks.
