Preparing Your Receiver

Notes:

•Be sure you connect the receiver’s right and left positive (+) and negative

(–)terminals to the speaker’s corre- sponding right and left positive (+) and negative (–) terminals.

•Fully insert the speaker wires to ensure a good connection. Leave extra wire at the back of the receiver so you do not disconnect the wires when you move the receiver.

Caution: To prevent a short circuit, twist the end of each conductor to be sure that stray speaker wire strands do not touch other speaker terminals or any other receiver terminals.
