1. To aim, point the display end of the 7400 horizontally at a 45° angle approximately 2 to
9 inches (5 to 20 cm) away from the target. You may have to adjust the angle at which
you hold the Dolphin if there is glare on the screen.

image. This is normal.

on the terminal screen. Hold the Dolphin terminal as still as possible when capturing the

the file depends on the information content of the image and will be approximately
4-8 K.
