To access the radio signal icon:

• Tap on the radio icon in the taskbar to display the radio qual-

ity dialog box.

Note: Moving in and out of the radio coverage area can have vary-

ing 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 pis-

tol 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.

• Hold the scanner farther away for larger bar codes.
