Scan The Entire Symbol; Hold At An Angle - Symbol P370 Keyless Reference Manual

Scan the Entire Symbol

• Your scan beam must cross every bar and space on the symbol.
• The larger the symbol, the farther away you should hold the scanner.
• Hold the scanner closer for symbols with bars that are close together.
• A short, Hi tone beep indicates a good decode.

Hold at an Angle

Do not hold the scanner directly over the bar code. Laser light reflecting directly back into
the scanner from the bar code is known as specular reflection. This specular reflection can
make decoding difficult.
You can tilt the scanner up to 65° forward or back and achieve a successful decode. Simple
practice quickly shows what tolerances to work within.
