4 P370/470 Keyless RF Scanners
Consult the P370/P470 Keyless RF Scanners Product Reference Guide for
programming instructions. If you need assistance, contact your local supplier or
the Symbol Support Center.
To scan:
1. Ensure the battery is charged.
2. Ensure the bar code is in the correct scanning range.
3. Aim and press the trigger. When the scanner has read the symbol:
- a beep sounds.
- the LED turns green.
- the red laser turns off.
Aiming
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. Specular
reflection can make decoding difficult.
The scanner can tilt up to 65° forward or back and achieve a successful decode.
Simple practice quickly shows what tolerances to work within.
Scan the Entire Symbol
- The scan beam must cross every bar and space on the symbol (as in the
left bar code below).
- Hold the scanner farther away for larger symbols.
