TROUBLESHOOTING

With proper care and handling, your mixer should give you years of trouble-free service. However, if your SSM-1250 is not working properly, follow these sugges- tions to see if you can eliminate the problem. If you cannot, take the mixer to your local RadioShack store for assistance.

Nothing works	Check the AC power connection and make sure the AC
	outlet is “live.”
	Check all the connections to the system (amplifier/
	receiver, input sources, and so on).
	Check the fuse. See “Replacing the Fuse” on Page 21.
No signal from an audio	Make sure the OFF/ON/TALKOVER switch is not set to

	Check the mixer’s and the source’s control settings.
	Check the connection between the mixer and the input
	source.

	the mixer.
