Note: Moving in and out of the radio coverage area can have varying effects on a network session. At times, you may need to renew your connection by logging in again.
2.7 Checking The Scanner
If your 7530 G2 is equipped with an internal scanner, you can test it to ensure that it is operating properly. Point the scanner window at a bar code that your scanner was designed to decode – for example, a
1D UPC bar code or 2D bar code. Press the SCAN button or the pistol trigger, and check for a valid decode on the hand-held screen.
2.7.1 Scanning Techniques
Note: The scanning techniques described here apply to internal and external scanners.
• Hold the scanner at an angle. Do not hold it perpendicular to the bar code.
• Do not hold the scanner directly over the bar code. In this position, light can reflect back into the scanner’s exit window and prevent a successful decode.
• Scan the entire bar code. If you are using a 1D or 2D scanner, make certain that the scan beam crosses every bar and space on the bar code, including the margins on either end of the symbol.
• If you are using a 2D imaging scanner, make certain the red, oval-shaped framing mark is centered within the bar code you want to scan.
• When using imaging scanners, do not move the scanner while decoding the bar code. Movement blurs the image.
