Charging the Battery
Before using the TC20 for the first time, charge the internal battery until the green Charging/Notification light
emitting diode (LED) remains lit. To charge the TC20 use a cradle with the appropriate power supply or USB cable
and power supply. For information about the accessories available for the TC20 see Accessories for more
information.
The internal battery charges from fully depleted to 90% in approximately four hours and from fully depleted to
100% in approximately five hours.
NOTE In many cases the 90% charge provides plenty of charge for daily use. A full 100% charge lasts for
approximately 10 hours of use.
Use only Zebra charging accessories and batteries. Charge batteries at room temperature with the TC20
in sleep mode.
Charge batteries in temperatures from 0°C to 40°C (32°F to 104°F). The TC20 or accessory always performs
battery charging in a safe and intelligent manner. At higher temperatures (e.g. approximately +37°C (+98°F)) the
TC20 or accessory may for small periods of time alternately enable and disable battery charging to keep the
battery at acceptable temperatures. The TC20 or accessory indicates when charging is disabled due to abnormal
temperatures via its LED and a notification appears on the display.
To charge the internal battery:
1. Connect the charging accessory to the appropriate power source.
2. Insert the TC20 into a cradle or attach to a USB cable. The TC20 turns on and begins charging. The
Charging/Notification LED blinks amber while charging, then turns solid green when fully charged.

IMPORTANT To determine the integrated scan engine in the device, go to Settings > About phone >
Hardware components > Scanner.
Imaging
The TC20 with an integrated 2D imager has the following features:
• Omnidirectional reading of a variety of barcode symbologies, including the most popular linear, postal,
PDF417, and 2D matrix code types.
• The ability to capture and download images to a host for a variety of imaging applications.
• Advanced intuitive laser aiming cross-hair and dot aiming for easy point-and-shoot operation.
The imager uses imaging technology to take a picture of a barcode, stores the resulting image in its memory, and
executes state-of-the-art software decoding algorithms to extract the barcode data from the image.
Operational Modes
The TC20 with an integrated imager supports two modes of operation, listed below. Activate each mode by
pressing the Scan button.
• Decode Mode: In this mode, the TC20 attempts to locate and decode enabled barcodes within its field of
view. The imager remains in this mode as long as the user holds the scan button, or until it decodes a
barcode.
NOTE To enable Pick List Mode, configure in DataWedge or set in an application using a API command.
• Pick List Mode: This mode allows the user to selectively decode a barcode when more than one barcode
is in the TC20’s field of view. To accomplish this, move the aiming crosshair or dot over the required
82
Data Capture
barcode to decode only this barcode. This feature is ideal for pick lists containing multiple barcodes and
manufacturing or transport labels containing more than one barcode type (either 1D or 2D).
NOTE To enable Basic MultiBarcode Mode, configure in DataWedge or set in an application using a API
command.
• Basic MultiBarcode Mode: In this mode, the TC20 attempts to locate and decode a specific number of
unique barcodes within its field of view. The TC20 remains in this mode as long as the user holds the scan
button, or until it decodes all the barcodes. Available on integrated SE2100 or SE4710 imagers only.
• The TC20 attempts to scan the programmed number of unique barcodes (from 2 through 10).
• If there are duplicate barcodes (same symbology type and data), only one of the duplicate barcodes is
decoded and the remainder are ignored. If the label has two duplicate barcodes plus another two
different barcodes, a maximum of three barcodes will be decoded from that label; one will be ignored
as a duplicate.
• Barcodes can be of multiple symbology types and still be acquired together. For example, if the
specified quantity for a Basic MultiBarcode scan is four, two barcodes can be symbology type Code
128 and the other two can be symbology type Code 39.
• If the specified number of unique barcodes is not initially in view of the TC20, the TC20 will not decode
any data until the device is moved to capture the additional barcode(s) or time out occurs. If the TC20
field of view contains a number of barcodes greater than the specified quantity, the TC20 randomly
decodes barcode(s) until the specified number of unique barcodes is reached. For example, if the
count is set to two and eight barcodes are in the field of view, the TC20 decodes the first two unique
barcodes it sees, returning the data in random order.
• Basic MultiBarcode Mode does not support concatenated barcodes.

Scanning Considerations
Typically, scanning is a simple matter of aim, scan, and decode and a few quick trial efforts master it. However,
consider the following to optimize scanning performance:
• Range: Any scanning device decodes well over a particular working range — minimum and maximum
distances from the barcode. This range varies according to barcode 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 barcodes being
scanned.
• Angle: Scanning angle is important for promoting quick decodes. When laser beams reflect directly back
into the scanner from the barcode, this specular reflection can “blind” the scanner. To avoid this, scan the
barcode 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.
• Hold the TC20 farther away for larger symbols
• Move the TC20 closer for symbols with bars that are close together.
Data Capture
NOTE Scanning procedures depend on the application and TC20 configuration. An application may use different
scanning procedures from the one listed above.

Wireless
This section provides information on the wireless features:
• Wireless Local Area Network (WLAN)
• Bluetooth.
Wireless Local Area Networks
Wireless local area networks (WLANs) allow the TC20 to communicate wirelessly inside a building. Before using
the TC20 on a WLAN, the facility must be set up with the required hardware to run the WLAN (sometimes known
as infrastructure). The infrastructure and the TC20 must both be properly configured to enable this communication.
Refer to the documentation provided with the infrastructure (access points (APs), access ports, switches, Radius
servers, etc.) for instructions on how to set up the infrastructure.
Once the infrastructure is set up to enforce the chosen WLAN security scheme, use the Wireless & networks
settings configure the TC20 to match the security scheme.
The TC20 supports the following WLAN security options:
• Open
• Wireless Equivalent Privacy (WEP).
• Wi-Fi Protected Access (WPA)/WPA2 Personal (PSK).
• Extensible Authentication Protocol (EAP).
The Status bar displays icons that indicate Wi-Fi network availability and Wi-Fi status. See Status Bar for more
information.
NOTE Turn off Wi-Fi when not using it, to extend the life of the battery.

5. Touch .
Bluetooth
Bluetooth-equipped devices can communicate without wires, using frequency-hopping spread spectrum (FHSS)
radio frequency (RF) to transmit and receive data in the 2.4 GHz Industry Scientific and Medical (ISM) band
(802.15.1). Bluetooth wireless technology is specifically designed for short-range (10 meters (32.8 feet))
communication and low power consumption.
Devices with Bluetooth capabilities can exchange information (e.g., files, appointments, and tasks) with other
Bluetooth enabled devices such as printers, access points, and other mobile devices.
The TC20 support Bluetooth Low Energy. Bluetooth Low Energy is targeted at applications in the healthcare,
fitness, security, and home entertainment industries. It provides reduced power consumption and cost while
maintaining standard Bluetooth range.
Adaptive Frequency Hopping
Adaptive Frequency Hopping (AFH) is a method of avoiding fixed frequency interferers, and can be used with
Bluetooth voice. All devices in the piconet (Bluetooth network) must be AFH-capable in order for AFH to work.
There is no AFH when connecting and discovering devices. Avoid making Bluetooth connections and discoveries
during critical 802.11b communications. AFH for Bluetooth consists of four main sections:
Wireless
• Channel Classification - A method of detecting an interference on a channel-by-channel basis, or
pre-defined channel mask.
• Link Management - Coordinates and distributes the AFH information to the rest of the Bluetooth network.
• Hop Sequence Modification - Avoids interference by selectively reducing the number of hopping channels.
• Channel Maintenance - A method for periodically re-evaluating the channels.
When AFH is enabled, the Bluetooth radio “hops around” (instead of through) the 802.11b high-rate channels. AFH
coexistence allows Enterprise devices to operate in any infrastructure.
The Bluetooth radio in this device operates as a Class 2 device power class. The maximum output power is 2.5
mW and the expected range is 10 meters (32.8 ft.). A definition of ranges based on power class is difficult to obtain
due to power and device differences, and whether one measures open space or closed office space.
NOTE It is not recommended to perform Bluetooth wireless technology inquiry when high rate 802.11b operation
is required.
Security
The current Bluetooth specification defines security at the link level. Application-level security is not specified. This
allows application developers to define security mechanisms tailored to their specific need. Link-level security
occurs between devices, not users, while application-level security can be implemented on a per-user basis. The
Bluetooth specification defines security algorithms and procedures required to authenticate devices, and if needed,
encrypt the data flowing on the link between the devices. Device authentication is a mandatory feature of Bluetooth
while link encryption is optional.
Pairing of Bluetooth devices is accomplished by creating an initialization key used to authenticate the devices and
create a link key for them. Entering a common personal identification number (PIN) in the devices being paired
generates the initialization key. The PIN is never sent over the air. By default, the Bluetooth stack responds with no
key when a key is requested (it is up to user to respond to the key request event). Authentication of Bluetooth
devices is based-upon a challenge-response transaction. Bluetooth allows for a PIN or passkey used to create
96
Wireless
other 128-bit keys used for security and encryption. The encryption key is derived from the link key used to
authenticate the pairing devices. Also worthy of note is the limited range and fast frequency hopping of the
Bluetooth radios that makes long-distance eavesdropping difficult.
Recommendations are:
• Perform pairing in a secure environment
• Keep PIN codes private and do not store the PIN codes in the device
• Implement application-level security.
Bluetooth Profiles
The device supports the following Bluetooth services:
• Service Discovery Protocol (SDP) - Handles the search for known and specific services as well as general
services.
• Serial Port Profile (SPP) - Allows use of RFCOMM protocol to emulate serial cable connection between
two Bluetooth peer devices. For example, connecting the device to a printer.
• Object Push Profile (OPP) - Allows the device to push and pull objects to and from a push server.
• Advanced Audio Distribution Profile (A2DP) - Allows the device to stream stereo-quality audio to a wireless
headset or wireless stereo speakers.
• Audio/Video Remote Control Profile (AVRCP) - Allows the device to control A/V equipment to which a user
has access. It may be used in concert with A2DP.
• Personal Area Network (PAN) - Allows the use of Bluetooth Network Encapsulation Protocol to provide L3
networking capabilities over a Bluetooth link. Only PANU role is supported.
• Human Interface Device Profile (HID) - Allows Bluetooth keyboards, pointing devices, gaming devices and
remote monitoring devices to connect to the device.
• Headset Profile (HSP) - Allows a hands-free device, such as a Bluetooth headset, to place and receive
calls on the device.
• Hands-Free Profile (HFP) - Allows car hands-free kits to communicate with the device in the car.
• Phone Book Access Profile (PBAP) - Allows exchange of Phone Book Objects between a car kit and a
mobile device to allow the car kit to display the name of the incoming caller; allow the car kit to download
the phone book so the user can initiate a call from the car display.
• Symbol Serial Interface (SSI) - Allows for communication with Bluetooth Imager.
• File Transfer Profile (FTP) - Provides the capability to browse, manipulate and transfer files in file system
of another system. Uses GOEP as a basis.
• Generic Attribute Profile (GATT) - Provides profile discovery and description services for Bluetooth Low
Energy protocol. It defines how attributes are grouped together into sets to form services.
• HID Over GATT Profile (HOGP) - Defines the procedures and features used by Bluetooth low energy HID
Devices using GATT and Bluetooth HID Hosts using GATT.
• Scan Parameters Profile (ScPP) - Provides devices with information to assist them in managing their
connection idle timeout and advertising parameters to optimize for power consumption and/or
reconnection latency.
