terns. Use speaker systems with impedance
ratings of 446 ohms. Before hooking up your
speaker system, be sure to check its impedance,
which should be indicated either on the back of
the speaker, or in the speaker instruction man-

HOOKING UP SPEAKERS

On the rear panel of the RX~840 are two sets
of speaker terminals, A" and a", to which

to terminals "R" of A" (or "3"), and the
speaker leads of the left-hand speaker to ter-
minals L" of A" (or 8"). Make sure that the
"+" speaker lead is connected to the "+" ter-
minal, and the "-" lead to the "-" terminal.
Strip 1.06m (3/8") of the polyvinyl chloride
insulation from the end of each speaker lead.
Twist the exposed strands tightly, and secure
the end with'a touch of solder.

The terminals are the push-insert type. Insert
the end of the lead into the hole while pushing
on the button. Then release the button; the
hole will close and the cord is firmly fixed.
