Installation and Wiring
• Only connect the GX/GP to a monitor
after turning both the GX/GP and the
monitor off.
• Do not short the VIDEO OUT con-
nector or apply external voltage to it.
Doing so may damage the GX/GP.
Connecting to a Monitor
1. Turn off the GX/GP and the monitor.
2. Connect the GX/GP and the monitor using an RGB
cable.
3. Turn on the GX/GP and the monitor. The GX/GP
screen appears on the monitor.
Note
• When the GX/GP is turned on, the VIDEO OUT
connector constantly transmits VGA signals.
• The monitor display may flicker if you place the GX/
GP or some other device close to it.
• Depending on the type of monitor, parts of the GX/GP
display may be cut off.
