INSTALL THE  
MONITOR  
POWER CORD  
Check first to make sure that the power cord you  
use is the correct type required for your area.  
To connect the tilt/swivel base to the monitor, align  
hooks with the sockets on bottom side of the  
monitor, and gently push the base towards the front  
of the monitor.  
This monitor has a universal power supply that  
allows operation in either 100/120V AC or 220/  
240V AC voltage area. No user-adjustment is re-  
quired.  
The 15-pin D-shell signal connector on the signal  
cable will connect easily to the video adapter  
output on your personal computer. Lock both  
screws on the connector to ensure a firm  
connection.  
First connect the power cord into your monitor’s  
power input socket, and then plug the other end  
into a 3-pin AC outlet. The power cord may be  
connected to either a wall socket or the power out-  
put socket on your PC, depending on the type of  
power cord supplied with your monitor.  
Turn the PC power switch ON. Then turn the  
monitor power switch ON, by pressing the switch  
inward. The green power indicator will light up.  
For units to be used at 120V AC:  
Use a UL Listed Cord Set consisting of a min.  
No. 18 AWG, Type SVT or SJT three-conductor  
a maximum of 15 ft. in length and a parallel blade,  
grounding type attachment plug rated 10A, 125V.  
Allow about 30 seconds for the CRT tube to warm  
up. Data will be displayed on the screen.  
If your display fails to function properly, please  
first refer to the section "Troubleshooting" in this  
manual.  
For units to be used at 240V AC (domestic use):  
Use a UL Listed Cord Set consisting of a min. No.  
18 AWG, Type SVT or SJT three-conductor cord  
a maximum of 15 ft. in length and a tandem blade,  
grounding type attachment plug rated 10A, 250V.  
For units to be used at 220/240V AC (outside of  
U.S.):  
Use a Cord Set consisting of a min. No.18 AWG  
cord and grounding type attachment plug rated  
15A, 250V. The cord set should have the appro-  
priate safety approvals for the country in which  
the equipment will be installed and marked HAR.
