1.0  WARRANTY INFORMAT I O N  

Patton Electronics warrants all Model 1045 components to be

free from defects, and will—at our option—repair or replace the product
should it fail within one year from the first date of shipment.

This warranty is limited to defects in workmanship or materials, and

does not cover customer damage, abuse or unauthorized modification.
If this product fails or does not perform as warranted, your sole
recourse shall be repair or replacement as described above.  Under no
condition shall Patton Electronics be liable for any damages incurred
by the use of this product.  These damages include, but are not limited
to, the following:  lost profits, lost savings and incidental or
consequential damages arising from the use of or inability to use this
product.  Patton Electronics specifically disclaims all other warranties,
expressed or implied, and the installation or use of this product shall be
deemed an acceptance of these terms by the user. 

1.1  RADIO AND TV INTERFERENCE

The Model 1045 generates and uses radio frequency energy, and if

not installed and used properly—that is, in strict accordance with the
manufacturer's instructions—may cause interference to radio and
television reception.  The Model 1045 has been tested and found to
comply with the limits for a Class A computing device in accordance
with the specifications in Subpart J of Part 15 of FCC rules, which are
designed to provide reasonable protection from such interference in a
commercial installation.  However, there is no guarantee that
interference will not occur in a particular installation.  If the Model 1045
does cause interference to radio or television reception, which can be
determined by disconnecting the unit, the user is encouraged to try to
correct the interference by one or more of the following measures:
moving the computing equipment away from the receiver, re-orienting
the receiving antenna and/or plugging the receiving equipment into a
different AC outlet (such that the computing equipment and receiver are
on different branches).

1.2  SERVICE

All warranty and non-warranty repairs must be returned freight

prepaid and insured to Patton Electronics.  All returns must have a
Return Materials Authorization number on the outside of the shipping
container.  This number may be obtained from Patton Electronics
Technical Service at (301) 975-1007.  

Packages received without an

RMA number will not be accepted.

Patton Electronics' technical staff is also available to answer any

questions that might arise concerning the installation or use of your
Model 1045.  Technical Service hours:  8AM to 5PM EST, Monday
through Friday.

2.2  DESCRIPTION

The Model 1045 high speed short range modem supports

synchronous and asynchronous data rates of 32, 56 and 64 Kbps.
Synchronous transmit clock options are internal, external and receive
loopback clock.  Deriving power from a 7.5V wall-mount transformer,
the Model 1045 supports distances to 6 miles over unconditioned
twisted pair.

The Model 1045 incorporates two V.54 test modes (local analog

loop and remote digital loop), which can be activated via the RS-232 or
V.35 interface or by a tiny, externally accessible switch.  Additionally, a
built-in V.52 BER test generator outputs 511 and 511E bit patterns
which can also be controlled by a switch on the case.  Five easy-to-
read LED indicators monitor power, transmit data, carrier detect, test
mode and test pattern.  For protection against ground loops and
transient surges, the Model 1045 incorporates both isolation
transformers and Silicon Avalanche Diode surge suppressors.

Housed in a miniature ABS plastic case, the Model 1045 comes

equipped with a female DB-25 connector and a choice of twisted pair
interfaces (RJ-11 jack or RJ-45 jack).  The Model 1045 is available in
an RS-232/V.24 version and a CCITT V.35 version.
