<Note>
• If the power cover has come off or been removed, do not use
the monitor with the power supply connected to both AC input
and DC input terminals.
• Use a shielded DC cable that is not longer than 2 m. A cable
that is 2 m or longer may cause screen noise.
Before using an external DC power supply, be sure to check
that the rating of the external DC power supply suits the
power requirements of this monitor.
Check the pin arrangements of the DC output terminal of the
external DC power supply and those of the DC IN socket of
this monitor to ensure that a connection will maintain the cor-
rect polarity.
If +12 V is accidentally connected the GND terminal, fire or
injury could result.
