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.
2. Press the ON/SCAN button to take an image. Use the live video image on the terminal screen as a guide for positioning and
aiming the terminal at the target. You may find it helpful to start by moving the terminal further away and then in closer to the
target. The active screen image will have a slightly degraded appearance compared to the captured image. This is normal.
3. Release the ON/SCAN button to capture the image when the desired image is displayed on the terminal screen. Hold the
Dolphin terminal as still as possible when capturing the image.
Basic steps for acquiring images using the Dolphin 7450 terminal are:
1. Point the display end of the 7450 directly at the target.
2. Pull the Scan Trigger to take the image. Use the live video image on the terminal screen as a guide for positioning and
aiming the terminal at the target. You may find it helpful to start by moving the terminal further away and then in closer to the
target. The active screen image will have a slightly degraded appearance compared to the captured image. This is normal.
3. Release the Scan Trigger to capture the image when the desired image is displayed on the terminal screen. Hold the
Dolphin terminal as still as possible when capturing the image.
The image quality and related file size are determined by the data compression method used by your software application. For
highest quality, take grayscale images. When saved, the image will be saved in JPEG file format. The size of the file depends
on the information content of the image and will be approximately 4-8 K.
