STATEMENT OF LIMITED WARRANTY FOR THE 3270 EMULATION
CARDS
(Product)
International Business Machines Corporation (IBM) gives you the fol-
lowing limited warranty for this Product only
if it was was originally
purchased for use and not resale, from IBM, an IBM Authorized
,,,,., Dealer for this Product or an IBM approved Reseller for this Product.
This Statement refers to such a purchase as "Original Purchase."
The Warranty Period is ONE YEAR. It starts on the date of Original
Purchase as shown on the receipt which establishes the proof of Ori-
ginal Purchase.
IBM warrants that on the date of Original Purchase this Product will
conform to IBM's official published specifications. IBM will make
these specifications available to you upon request. During the War-
ranty Period, IBM or an IBM Authorized Dealer will provide warranty
service at no additional charge. You will receive warranty service if
this Product is (1) defective in material or workmanship or (2) other-
wise not in good working order. This warranty service will be either
repair or exchange, as determined by IBM. Warranty service does
not apply to certain Product failures. These failures are those which
result from accident, disaster, misuse, abuse, another product,
non-IBM modification, or service of the Product by other than IBM or
an IBM Authorized Dealer for this Product. Exchange service is not
available to you if the Product you present for exchange is defaced.
' If this Product is a feature, warranty applies only when the feature is
used in a machine for which it was designed. To obtain warranty
service for a feature, you may be required to present the feature with
such a machine.
Before you present this Product for warranty service, remove all pro-
grams, data and removable storage media. Products and parts pro-
vided to you as a result of warranty service may not be new.
However, they will be in good working order. These Products and
parts become your property upon completion of warranty service. At
the same time, the replaced Products or parts become the property of
IBM or the IBM Authorized Dealer.
iii

You may be required to present the proof of Original Purchase to IBM
or an IBM Authorized Dealer when obtaining warranty service. To
obtain service from an IBM Authorized Dealer you should contact the
Dealer. To obtain service from IBM you should contact IBM by calling
1-800-IBM-2569. You may be able to ship this Product to an IBM des-
ignated
location for warranty service. When shipping a Product to
IBM, you are
responsible to insure it or bear the risk of loss or
damage in transit. You are also responsible to prepay shipping .._
charges and to use the original shipping container or equivalent. IBM
will prepay return shipping charges to an IBM-selected carrier, within
the United States and Puerto Rico. In such case IBM will be respon-
sible for risk of loss or damage to the Product while in transit from
IBM. IBM is similarly responsible for the Product while it is in IBM's
possession.
If
this Product was purchased directly from IBM, the Date of Installa-
tion is considered the date of Original Purchase. To obtain warranty
service from IBM you need not present proof of Original Purchase.
However, to
obtain warranty service from an IBM Authorized Dealer
you should contact IBM for proof of Original Purchase.
If you
transfer this Product to another user, warranty service under
the terms and conditions of this Statement is available to that user.
Warranty service is available to that user for the remainder of the
Warranty Period. Therefore, you should transfer the proof of Original
Purchase to that user.
If you have any
question about this limited warranty, contact your IBM
Authorized Dealer or IBM approved Reseller. You may also call IBM """
Direct at 1-800-IBM-2468.
This
limited warranty will apply only to a Product purchased in the
United States
or Puerto Rico and located in the United States or
Puerto Rico.
ALL EXPRESS AND IMPLIED WARRANTIES FOR THIS PRODUCT,
INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND
FITNESS
FOR A PARTICULAR PURPOSE, ARE LIMITED IN DURATION
TO THE WARRANTY PERIOD. NO WARRANTIES, EXPRESS OR
IMPLIED, WILL APPLY AFTER THIS PERIOD.

lasts, so the above limitations may not apply to you.
This
warranty gives you specific legal rights. You may also have
other rights which vary from state to state.

~-----------------
The
following
statement
applies
to
the
IBM
products
covered
in
this
manual,
unless
otherwise
specified
herein.
The
statement
for
other
IBM
products
will
appear
in
their
accompanying
materials.
When a 3270
Card
is
connected
to
an FCC Class A
host
as a
periph-
eral
using
coaxial
cable,
the
following
warning
applies:
Federal Communications Commission (FCC) Statement
Note:
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
instruction
manual,
may
cause
harmful
interfer-
ence
to
radio
communications.
Operation
of
this
equipment
in a
resi-
dential
area
is
likely
to
cause
harmful
interference,
in
which
case
the
user
will
be
required
to
correct
the
interference
at
his
own
expense.
Properly
shielded
and
grounded
cables
and
connectors
must
be
used
in
order
to
meet
FCC
emission
limits.
IBM
is not
responsible
for
any
radio
or
television
interference
caused
by
using
other
than
recom-
mended
cables
and
connectors
or
by
unauthorized
changes
or
modifi-
cations
to
this
equipment.
Unauthorized
changes
or
modifications
could
void
the
user's
authority
to
operate
the
equipment.
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.

When the coaxial attachment to the host is not connected, this equip-
ment complies with the FCC Class B limits and the following warning
applies:
Federal Communications Commission (FCC) Statement
Note:
This equipment has been tested and found to comply with the
_ limits for a Class B digital device, pursuant to Part 15 of the FCC
Rules.
These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equip-
ment generates, uses and can radiate radio frequency energy and, if
not installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or tele-
vision reception, which can be determined by turning the equipment
off and on, the user is encouraged to try to correct the interference by
one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.
• Consult an authorized IBM dealer or service representative for
help.
Properly shielded and grounded cables and connectors must be used
in order to meet FCC emission limits. Proper cables and connectors
are available from authorized IBM dealers. IBM is not responsible
, for any radio or television interference caused by using other than
recommended cables and connectors or by unauthorized changes or
modifications to this equipment. Unauthorized changes or modifica-
tions could void the user's authority to operate the equipment.
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.

cards, but older level diagnostic programs may not work with
these cards.

Signal Cable Considerations
When a 3270
Card
is
attached
to
a host
system,
consider
the
fol-
lowing
practices
for
installing
signal
cable:
•
Installation
Cable
runs
(indoor
and
outdoor)
Types
of
signal
cables
and
specifications
(coaxial
and
twisted-pair)
Signal
cable
and
power
line
separation
Cable
labeling
and
testing
•
Cable
accessories.
Outdoor
runs
require
additional
installation
guidelines,
including
lightning
protection.
For
more
information,
refer
to
the
signal
cable
publications
listed
in
