External Speaker Connections

External speakers may be connected to the monitor to reproduce sound from
VIDEO 1, VIDEO 2, RGB 1 or RGB 2 signal sources.
External speakers may be connected directly to the EXTERNAL SPEAKERS
terminals or indirectly by connecting a stereo system amplifier to the audio
outputs.

1. Strip the ends of the speaker wires.
2. Press down a button below the EXTERNAL SPEAKERS terminals, insert
the speaker wire and release the button to secure a speaker wire connec-
tion:

viewed from the front) positive (+) wire to RIGHT +.
[b] Connect the right speaker negative (-) wire to RIGHT -.
[c] Connect the left speaker negative (-) wire to LEFT -.
[d ]Connect the left speaker positive wire (+) to LEFT +.
3. Set SPEAKER SELECT switch at EXT.
NOTE: The speaker cables must be less than 3m in length.
If non-shielded speakers are used, they must be located a minimum of 4 feet
away from the monitor.
