EL232 XPCD Limited Warranty

Rice Lake Weighing Systems (RLWS) warrants that all RLWS equipment and systems properly installed by a
Distributor or Original Equipment Manufacturer (OEM) will operate per written specifications as confirmed by
the Distributor/OEM and accepted by RLWS. All systems and components are warranted against defects in
materials and workmanship for one year. 

RLWS warrants that the equipment sold hereunder will conform to the current written specifications authorized
by RLWS. RLWS warrants the equipment against faulty workmanship and defective materials. If any equipment
fails to conform to these warranties, RLWS will, at its option, repair or replace such goods returned within the
warranty period subject to the following conditions:

Upon discovery by Buyer of such nonconformity, RLWS will be given prompt written notice with a
detailed explanation of the alleged deficiencies.

Individual electronic components returned to RLWS for warranty purposes must be packaged to
prevent electrostatic discharge (ESD) damage in shipment. Packaging requirements are listed in a
publication, Protecting Your Components From Static Damage in Shipment, available from RLWS
Equipment Return Department.

Examination of such equipment by RLWS confirms that the nonconformity actually exists, and was
not caused by accident, misuse, neglect, alteration, improper installation, improper repair or
improper testing; RLWS shall be the sole judge of all alleged non-conformities.

Such equipment has not been modified, altered, or changed by any person other than RLWS or its
duly authorized repair agents.

RLWS will have a reasonable time to repair or replace the defective equipment. Buyer is responsible
for shipping charges both ways.

In no event will RLWS be responsible for travel time or on-location repairs, including assembly or
disassembly of equipment, nor will RLWS be liable for the cost of any repairs made by others.
