following sections:
• Understanding the Lights
• Understanding the Beeps
• Scanning Bar Codes

Chapter 2 — Scanning with the SG20T
Understanding the Lights
The SG20T uses the Intermec Ready-to-Work™ light and Status light
to communicate information about your scanner.
Intermec Ready-to-Work Indicator
The Intermec-Ready-to-Work indicator™ (blue LED) indicates that
the scanner is ready to scan bar codes. This light stays on all the time
when the scanner is ready to work however your scanner will also flash
status information using green and red lights. See the Status Light
information in the next section.
Blue Intermec Ready-to-Work Indicator
Light State What it Means
Off Scanner is not ready to scan bar codes.
On The SG20T is ready to scan bar codes.
Note: By default the Intermec Ready-to-Work light is enabled however
you can disable the light if desired. You can also change the color. See
EasySet version 5. 6. 5. 1. for more information.

SG20T Tethered Scanner User’s Guide 11
Chapter 2 — Scanning with the SG20T
Understanding the Beeps
The SG20T also beeps to give you audio feedback when performing
some functions. For example, you hear a beep each time you scan a
valid bar code.
Default SG20T Beep Descriptions

Scanning Bar Codes
For the SG20THP and SG20THPHC do not look directly into the
window area or at a reflection of the laser framing beam while
scanning. Long-term exposure to the laser framing beam can
damage your vision.
The SG20T contains either a 1D imager (SG20T1D), a 2D imager
(SG20T2D or SG20T2DHC) or high performance 2D imager
(SG20THP or SG20THC) to scan bar code data. The type of scan
engine you are using and the type of bar code you are decoding
determines the way you scan the bar code.
When you unpack the SG20T, these bar code symbologies are enabled:
• Code 39
• Code 128 / GS1-128
• EAN/UPC
• PDF417 (all models except SG20T1D)
• DataMatrix (all models except SG20T1D)
12 SG20T Tethered Scanner User’s Guide
Chapter 2 — Scanning with the SG20T
If you are using bar code labels that are encoded in a different
symbology, you need to enable the symbology on your SG20T. Use
EasySet version 5.6.5.1 or later to enable and disable symbologies for
your scanner.
To scan with a 1D imager
1 Point the SG20T at the bar code label and hold the SG20T at a
slight angle 15 to 25 cm (6 to 10 in) from the label.
2 Pull the trigger, and direct the red beam so that it falls across all
bars in the bar code label.
Use this test bar code:
Code 39 Test Bar Code
*123456*
*123456*
Tip: Depending on your screen resolution, you can scan bar codes
displayed on your computer screen.
By default, when the SG20T successfully reads a bar code label, the
SG20T beeps one time, the status light briefly turns green, and the
scanner beam turns off.

2 Pull the trigger and use the laser framing or aiming beam to
position the imager over the bar code or area to capture.
Example: SG20THP Laser Framing
When bar code labels are printed close to each other, try to frame or
aim only the bar code you want to read, to avoid reading the wrong bar
code.
14 SG20T Tethered Scanner User’s Guide
By default, when the SG20T successfully reads a bar code label, the
SG20T beeps one time, the status light briefly turns green, and the
scanner lighting turns off.
3 Release the trigger.
Hands-Free Scanning
The SG20T is a handheld scanner however you can scan items
without having to hold your scanner in your hand. To do hands-free
scanning, you will need to change the triggering mode to Autostand.
To activate, see
Autostand Triggering Mode
Autostand mode is different depending on the scanner model. This
section explains the difference between:
• Autostand for all models except SG20T1D
• Autostand for SG20T1D
Autostand For All Models Except SG20T1D
Autostand is a mix of Level and Presentation triggering modes. When
in Level mode you simply pull the trigger to scan a bar code (hand
held scanning). After a period of inactivity the scanner switches to
Presentation mode (configurable timeout). In this mode the scanner
turns on automatically when it detects movement in front of the
scanner window. This allows you to use your scanner for hands-free
scanning. To return to Level mode pull the trigger.
Chapter 2 — Scanning with the SG20T
“Hands-Free Scanning” on page 29.
Autostand For SG20T1D
When using the 1D model Autostand is a mix of Level and Flashing
triggering modes. When in Level mode you simply pull the trigger to
scan a bar code (handheld scanning). After a period of inactivity the
scanner switches to Flashing mode (configurable timeout). When the
scanner is flashing you can present a bar code in front of the scanner
window and it will be scanned. To return to Level mode pull the
trigger.
