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.
WARNING: Speakers that are installed next to the monitor must be
shielded against electromagnetic radiation which can cause color distortion
in the CRT and is not covered under the warranty.
If non-shielded speakers are used, they must be located a minimum of 4 feet
away from the monitor.
CAUTION: Unplug the monitor and all connected components before con-
necting external speakers. Use only speakers with 8-ohm impedance and a
power output rating of 5 watts or more.
