USING THE R800 RECEIVERS &SPK 800 SPEAKERS

The R800 is a combination FM receiver/amplifier/speaker. The SPK 800 is driven by the
amplifier within the R800. Both are compact, self-contained, and portable. Most rooms will
require just the two speakers, placed in either front corner of the room. For larger rooms,
additional speakers may be added to the rear corners.
MAIN FEATURES OFTHE R800 RECEIVER/SPEAKER
FM/Auxiliary Switch
For normal use with the T31 Transmitter, the FM switch should be ON. When using an aux-
iliary input from a VCR, tape player, preamp, or other source, turn the FM switch OFF.
FM Channel Switch
The selected receiver channel must match the transmitter channel. The SoundFocusSystem is
pre-set to channel 3 (72.9 MHz). Change the receiver channel only if the transmitter channel
has been changed. See page 12 for instructions on changing the transmitter channel.
