User's Guide 3
Introduction
The Duet™ scanner from PSC®, shown in Figure 1, delivers high
performance in a small, fixed scanner which can also be used as a
targeted handheld scanner. Its innovative design maximizes produc-
tivity, and minimizes operator stress, strain and fatigue.
The Duet scanner's compact size uses very little counter space. The
product is designed for durability, prolonged life, and low mainte-
nance costs. With three scanning options: fixed, portable, and
targeted handheld, the Duet scanner is versatile and flexible. You
can bring small items to the scanner, or take the scanner to large
bulky items.

presentation and sweep scanning, and the rear scan window for
targeted handheld scanning. Figure 2 shows the Duet scanner used

Operational Overview
The scanner has three operational modes:
• Fixed/Portable Mode
• Targeted Handheld Mode
• Sleep Mode
This section describes the three operational modes while the section
How to Scan, describes how to use the scanner in the Fixed/Portable
and Targeted operational modes.
Fixed/Portable Mode
In the Fixed Mode, the scanner remains fixed in the stand and reads
while a bar code is swept past or presented to the front scan win-
dow. You can also remove the scanner from the stand and present
or sweep the scanner over the bar code using the front scan window
(Portable Mode).
Figure 3 shows the scanner in the Fixed Mode with (1), the item
presented to the scanner, and (2), the Portable Mode where the
scanner is presented to the item.

Targeted Handheld Mode
Remove the scanner from the stand to use it in the Targeted Handheld
Mode. Pressing the trigger switch enables targeted scanning. (See
Figure 4). The Targeted Handheld Mode allows the scanner to read
bar codes selectively. A Pointer Line provides a visual aid for aiming
the single scan line at the bar code. Press the switch once for each bar
code scanned.
This mode is particularly useful for reading a single bar code where
multiple bar codes exist in the same area. The Fixed/Portable Mode
is disabled while the trigger switch is pressed.
