Quick Reference
The * key is a special key that can be programmed for custom
specific operations. Ask your system administrator for more
information.
Host Communications
With some terminal types, the Phaser is unable to answer host
terminal polls until the appropriate host type is selected. This may
result in an error message generated by the host computer. Contact
your System Administrator for assistance.
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. This strong light can “blind” the scanner and
make decoding difficult. The area where specular reflection occurs
is known as a “dead zone”.
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.
