LEARNING THE BASICS
OVERVIEW This section provides instructions on basic features and functions of
the 475 Field Communicator. It also provides information on assembly,
components, starting, entering standby, shutting down, settings,
applications, and maintaining the 475 Field Communicator. The
functionality described in this section is based on system software
version 3.8.
SAFETY MESSAGES Procedures and instructions in this section may require special
precautions to ensure the safety of the personnel performing the
operation. Information that raises potential safety issues is indicated by
a warning symbol ( ). Refer to the safety messages before
performing an operation preceded by this symbol. See the
“Troubleshooting” section for more warning messages.
This equipment has been tested and found to comply with the
limits for a Class A digital device, pursuant to part 15 of the FCC
Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and
can radiate radio frequency energy and, if not installed and used in
accordance with the user’s manual, may cause harmful
interference to radio communications. Operation of this equipment
in a residential area is likely to cause harmful interference in which
case the user will be required to correct the interference at his own
expense.
This device complies with Part 15 of the FCC Rules. Operation is
subject to the following two conditions: (1) this device may not
cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause
undesired operation.
Any modifications made to this device that are not approved by
Emerson Process Management may void the authority granted to
the user by the FCC to operate this equipment.
This Class A digital apparatus complies with Canadian ICES-003.
IMPORTANT NOTICE
You can install or remove the Lithium Ion (Li-Ion) battery (Power
Module) in a hazardous area environment.You cannot charge the
battery in this environment because the power supply/charger
(00375-0003-0005) is not IS-approved.

475 FIELD
COMMUNICATOR
OVERVIEW
The 475 Field Communicator supports HART and FOUNDATION fieldbus
devices, letting you configure, maintain, or troubleshoot devices. When
using the 475 Field Communicator to communicate with devices,
follow all standards and procedures applicable to the location. Failure
to comply may result in equipment damage and/or personal injury. Be
sure to understand and comply with the sections in this manual.
The 475 Field Communicator includes a color LCD touch screen, a
Li-Ion battery (Power Module), a SH3 processor, memory components,
System Card, and integral communication and measurement circuitry.
The Field Communicator also supports multiple languages. See the
readme file included with the Field Communicator Easy Upgrade Utility
or www.fieldcommunicator.com for more information.
Device interoperability The 475 Field Communicator is designed to operate with a wide range
of HART and FOUNDATION fieldbus devices independent of device
manufacturer. Device interoperability is achieved through the
Electronic Device Description Language (EDDL) technology supported
by the HART Communication Foundation and Fieldbus Foundation.
Basic testing is performed on all device descriptions. Each device
manufacturer is asked to certify that they thoroughly tested their
devices with the 475 Field Communicator. If certification is not
received, a warning message displays when you attempt to
communicate with an untested device. New device descriptions are
available from the Field Communicator Easy Upgrade Utility or the
Resource CD or DVD.
WARNING
Learning the basics 11
Working in a hazardous
area
A 475 Field Communicator that meets the Intrinsic Safety requirements
(I/S-approved) can be used in Zone 0 (FM and CSA only), Zone 1, or
Zone 2, for Group IIC, and Class I, Division 1 and Division 2, Groups A,
B, C, and D locations.
An IS-approved 475 Field Communicator may be connected to loops
or segments that are attached to equipment located in Zone 0, Zone 1,
Zone 2, for Group IIC; Zone 20, Zone 21, Zone 22, and Class I,
Division 1 and Division 2, Groups A, B, C, and D locations.
IS-approved 475 Field Communicators are ordered with the KL option
and have an additional label on the back of the 475 that lists the
approvals.
See Appendix B “Product certifications” for more information about IS
approvals and installations.
CAUTION
You can install or remove the Li-Ion battery in a hazardous area
environment. You cannot charge the battery in this environment
because the power supply/charger is not IS-approved.
Battery and
power supply/charger
The 475 Field Communicator is powered by a Li-Ion battery that has a
green, 6-pin connector. The power supply/charger also has a green
connector to match the appropriate connector on the battery. See
Figure 2-1 for the location of the connector.
Prior to using the 475 Field Communicator without the power
supply/charger connected, fully charge the battery.
Guidelines and precautions
Understand and follow the guidelines and precautions below before
using the battery or power supply/charger.
• When transporting a Li-Ion battery, follow all applicable regulations.
• Protect the battery and power supply/charger from moisture, and
respect operating and storage temperature limits. See Appendix A
“Reference data” for more information.
• Do not cover the battery or power supply/charger, subject it to
prolonged periods of direct sunlight, or place it upon or next to
heat-sensitive materials.
• Charge the battery with only the Field Communicator power
supply/charger. The power supply/charger should not be used with
other products. Failure to comply may permanently damage your
475 Field Communicator and will void the IS approval and the
warranty.
• Do not open or modify the battery or power supply/charger. There
are no user-serviceable components or safety elements inside.
Opening or modifying them will void the warranty and could cause
personal harm.

Checking the remaining charge
To view the remaining charge, press the Charge Indicator button on
the lower left side of the battery. See Figure 2-1 for the location of this
button. When you press and release the button, the lights above the
button slowly illuminate to display the charge remaining. Each light
represents 20 percent of the charge. The battery is fully charged when
all of the lights are illuminated.
You can also check the remaining charge from the Settings menu on
the Field Communicator Main Menu. See “Power” on page 25 for more
information.

Charging the battery
Prior to first portable use, fully charge the battery. The battery can be
charged separately or while attached to the 475 Field Communicator.
The 475 Field Communicator is fully operable while the battery is
recharging, and a full charge takes 2-3 hours. An overcharge condition
will not occur if the power supply/charger remains connected.
CAUTION
You can remove and install the Li-Ion battery in a hazardous area
environment. You cannot charge the battery in this environment
because the power supply/charger is not IS-approved.
Learning the basics 13
To charge the battery:
1.Plug the power supply/charger into a power outlet.
2.Plug the green power supply/charger connector into the green
connector on the battery. The flat side of the power supply/charger
connector should face the front of the 475 or the inside of the battery,
if the battery is not attached to the 475. The battery is fully charged
when the light on the power supply/charger is green.
