from the HDD’s “Audio LEFT” (White) and “Audio RIGHT” (RED) Output ports to the
modulators Left and Right audio ports.

use of F to RCA adaptors may be necessary to make the connection.

source and/or power voltage can damage the HDD. The use of a surge protector and a UPS
is highly recommended. Product warranty does not cover surge or spike damages.
