Resetting the Wearable Terminal
There are two types of resets, warm boot and cold boot. A warm boot restarts the wearable terminal by closing all
running programs.
A cold boot also restarts the wearable terminal, but erases all stored records and entries in RAM. Data saved in
flash memory or a memory card is not lost. In addition it returns formats, preferences and other settings to the
factory default settings.
Perform a warm boot first. This restarts the wearable terminal and saves all stored records and entries. If the
wearable terminal still does not respond, perform a cold boot.

Performing a Warm Boot
Hold down the Power button for approximately five seconds. As soon as the wearable terminal starts to perform a
warm boot release the Power button.

Performing a Cold Boot
A cold boot restarts the wearable terminal and erases all user stored records and entries that are not saved in flash
memory (Application and Platform folders). Never perform a cold boot unless a warm boot does not solve the
problem.
NOTE

Any data previously synchronized with a computer can be restored during the next ActiveSync operation.

To perform a cold boot press and simultaneously hold the 1, 9 and Power button. Do not hold down any other keys
or buttons. The wearable terminal initializes.

Using the Wearable Terminal 2 - 15

Data Capture
Wearable terminals used with an optional wearable laser scanner allow collection of data by scanning one
dimensional bar codes.

Laser Scanning
Wearable terminals with an optional wearable laser scanner have the following features:

• Reading of a variety of bar code symbologies, including the most popular linear, postal, and 1-D code types.
• Advanced intuitive laser aiming for easy point-and-shoot operation.

Scanning Considerations
Typically, scanning is a simple matter of aim, scan/decode and a few quick trial efforts master it. However, two
important considerations can be used to optimize any scanning performance:

• Range
Any scanning device decodes well over a particular working range — minimum and maximum distances from
the bar code. This range varies according to bar code density and scanning device optics.
Scanning within range brings quick and constant decodes; scanning too close or too far away prevents
decodes. Move the scanner closer and further away to find the right working range for the bar codes being
scanned. However, the situation is complicated by the availability of various integrated scanning modules. The
best way to specify the appropriate working range per bar code density is through a chart called a decode zone
for each scan module. A decode zone simply plots working range as a function of minimum element widths of
bar code symbols.

• Angle
Scanning angle is important for promoting quick decodes. When laser beams reflect directly back into the
scanner from the bar code, this specular reflection can “blind” the scanner.
To avoid this, scan the bar code so that the beam does not bounce directly back. But don’t scan at too sharp an
angle; the scanner needs to collect scattered reflections from the scan to make a successful decode. Practice
quickly shows what tolerances to work within.
NOTE

Contact the Symbol Support Center if chronic scanning difficulties develop. Decoding of properly printed bar
codes should be quick and effortless.

Scanning Bar Codes
1.

Ensure that a scan enabled application is loaded on the wearable terminal.

Aim the scan exit window at the bar code.

Press the trigger.

• Ensure the red scan beam covers the entire bar code. The red scan LED lights to indicate that the laser is
on. The green scan LED lights. An audible beep might sound, if the application determines, to indicate the
bar code was decoded successfully.

2 - 16 WT4070/90 Wearable Terminal User Guide

Figure 2-11 Laser Scanner Aiming Pattern

Release the trigger.

Scanning Tips
Optimal scanning distance varies with bar code density and scanner optics.

• Hold the scanner farther away for larger symbols.
• Move the scanner closer for symbols with bars that are close together.
NOTE

Scanning procedures depend on the application and wearable terminal configuration. An application may
use different scanning procedures from the one listed above.

Scan LED Indicator
The LED on the scanner provides a visual indication of the scan status.

Freezer Pouch
The freezer pouch allows the user to use the wearable terminal in a freezer environment on the hip or wrist for use
in voice picking applications. An RS309 or RS409 scanner with an extended cable is required when mounting the
freezer pouch on the hip mount, if scanning is also part of the application.
In order to keep the wearable terminal at a safe operating temperature in a meat or ice cream freezer, the freezer
pouch insulates the wearable terminal to keep the heat generated by the wearable terminal within the pouch. The
pouch is not heated. There are no batteries to worry about or electronics within the pouch.
The freezer pouch can be either hip-mounted or wrist-mounted. For hip-mounting, there is a belt loop on its back
for attached a belt (sold separately). For wrist-mounting, customers can buy either a set of standard-length or
longer-length wrist straps and use them with the pouch. The longer-length wrist straps are recommended for
wrist-mounting over coats. The freezer pouch has openings on each side for wearable scanners and headset
adapters.
While the freezer pouch is designed to allow workers to use the wearable terminal in meat and ice cream freezers,
there are some very important limitations to follow:

• Do not use in environments that are below -30°C (-22°F).
• Do not allow the wearable terminal (with or without the freezer pouch) to remain in the suspend mode in
environments below -20°C (-4°F) for more than 10 minutes. This prevents the wearable terminal from cooling
down to the ambient freezer temperature. The pouch maintains the wearable terminal at a sufficient
temperature while it is in use, but lengthy periods of inactivity brings the wearable terminal below its
operating temperature.

• Do not store wearable terminals in the meat or ice cream freezer. As explained above, this would allow the
wearable terminals to chill to the ambient freezer temperature, which is below their operating temperature.
Furthermore, if batteries were left in wearable terminals stored in the freezer, the batteries themselves could
freeze, which could damage them. At the least, they would not function while frozen.

• Batteries cannot be charged below 0°C (32°F). Motorola cradles and battery chargers have an automatic
shut-off to insure this.

• If using wearable scanners with the wearable terminal in the meat or ice cream freezer for a shift, remember
that the RS309 freezer configuration is the correct scanner to choose, due to its lower operating temperature
range and its desiccant pack to remove condensation.
Slide the wearable terminal into the freezer pouch.

T
TCP/IP. (Transmission Control Protocol/Internet Protocol) A communications protocol used to internetwork dissimilar
systems. This standard is the protocol of the Internet and has become the global standard for communications. TCP
provides transport functions, which ensures that the total amount of bytes sent is received correctly at the other end.
UDP is an alternate transport that does not guarantee delivery. It is widely used for real-time voice and video
transmissions where erroneous packets are not retransmitted. IP provides the routing mechanism. TCP/IP is a routable
protocol, which means that all messages contain not only the address of the destination station, but the address of a
destination network. This allows TCP/IP messages to be sent to multiple networks within an organization or around the
world, hence its use in the worldwide Internet. Every client and server in a TCP/IP network requires an IP address, which
is either permanently assigned or dynamically assigned at startup.
Telnet. A terminal emulation protocol commonly used on the Internet and TCP/IP-based networks. It allows a user at a
terminal or computer to log onto a remote device and run a program.
Terminal. See Wearable Terminal.
Terminal Emulation. A “terminal emulation” emulates a character-based mainframe session on a remote non-mainframe
terminal, including all display features, commands and function keys. The WT4090 Series supports Terminal Emulations
in 3270, 5250 and VT220.
TFTP. (Trivial File Transfer Protocol) A version of the TCP/IP FTP (File Transfer Protocol) protocol that has no directory or
password capability. It is the protocol used for upgrading firmware, downloading software and remote booting of diskless
devices.
Tolerance. Allowable deviation from the nominal bar or space width.
Transmission Control Protocol/Internet Protocol. See TCP/IP.
Transport Layer Security (TLS). TLS is a protocol that ensures privacy between communicating applications and their
users on the Internet. When a server and client communicate, TLS ensures that no third party may eavesdrop or tamper
with any message. TLS is the successor to the Secure Sockets Layer (SSL).
Trivial File Transfer Protocol. See TFTP.

U
UPC. Universal Product Code. A relatively complex numeric symbology. Each character consists of two bars and two
spaces, each of which is any of four widths. The standard symbology for retail food packages in the United States.
UDP. User Datagram Protocol. A protocol within the IP protocol suite that is used in place of TCP when a reliable delivery
is not required. For example, UDP is used for real-time audio and video traffic where lost packets are simply ignored,
because there is no time to retransmit. If UDP is used and a reliable delivery is required, packet sequence checking and
error notification must be written into the applications.

Glossary - 9

U
Visible Laser Diode (VLD). A solid state device which produces visible laser light.

W
Warm Boot. A warm boot restarts the wearable terminal by closing all running programs. All data that is not saved to flash
