Use the Computer as a Two-Way Radio
Use the Push To Talk (PTT) feature with an audio application, such as
iTalkie™, to communicate with other computers over the 802.11 radio
network. For more information about the iTalkie application, go to
www.tabletmedia.com/iTalkie.html.
• After you install an audio application, press and hold the PTT key
to talk to another computer.
How to Read Bar Codes
The computer has an internal imager that can read 1D and 2D bar
code symbologies, composite symbologies, and postal codes:
• The CK3R computer has an EA31 area imager.
• The CK3X computer has either an EA30 area imager, an EX25
near-far range area imager, or an 5603ER(extended range) area
imager.
You can also connect the computer to these external scanners:
• Cordless scanners, such as the SF51, SG20, and SR61, using
Bluetooth communications
• Tethered scanners, such as the SG10, SG20, SR30, and the SR61,
using a CK3 RS-232 adapter (Model AA21)
Read Bar Codes with the Imager
All of the imagers support omni-directional scanning and include an
aiming beam to help you correctly frame bar codes.
Before you start reading bar codes, use Intermec Settings to:
• enable only the bar code symbologies that you need.
• choose the predefined imager mode that best suits your
environment.
