8. Manufacturers
Servicing and Warranty
Arrangements.
Each instrument has been carefully inspected
and calibrated prior to despatch from our
factory in order to ensure its rigid conformity
with the requirements of our specification.
All technical information relating to
individual instruments is filed under the
instrument's serial number. It is important,
therefore to always quote this number in any
correspondence with the manufacturers. The
serial number is located on the back of the
instrument.
The manufacturers undertake to rectify
any defect in the instrument that is directly
attributable to faulty design or assembly and
which becomes apparent during the first 12
months from the date of the initial calibration.
Many of the specified components used in the
instrument are subject to separate warranties
by their actual manufacturers and in all cases
benefit of these undertakings will be passed
on to the user. However, CEL's liability is
limited to items of their own manufacture and
they do not accept liability for any loss
resulting from the operation or interpretation of
the results of this equipment.
In the event of a malfunction developing
the instrument should be carefully packed and
returned to either the manufacturer's agent in
the territory or, in the case of domestic sales,
to our UK factory, along with a detailed
description of the fault. The necessary repairs
will be undertaken and the instrument
returned as soon as possible. After the
warranty has expired, except on approved
accounts, service work is undertaken against
quotations and all packing and transit costs are
charged extra. In the case of sales in the UK,
service contracts are available on request.
9. CEL-160
Post-Production
Software Amendment
Important changes to the "Select Frequency
Analyzer" program are incorporated in your
CEL-160 Graphic Recorder when it is fitted
with version 9 software.
These changes will affect those
applications where external frequency
analyzers are used in conjunction with the
CEL-160.
The changes apply to all production
units despatched from the factory from 1 st
March 1988 onwards. The date of despatch is
recorded in the handbook. Instruments which
are returned to our Service Department for
software upgrades will also be subject to
these software changes.
The software version fitted to all
CEL-160 Graphic Recorders can be identified
from the label on the instrument base, close to
the instrument serial number label. The final
two digits define the software issue fitted and
so these instructions apply to all instruments
for which the final code digits are "09".
Now turn to page 8 of the handbook and
consult the list of frequency analysers
contained in the section on key pad "F - Select
Frequency Analyzer Type". The list contained in
the handbook is valid for all software issues
prior to version 09. In version 09 it is replaced
by the table in Figure 11.
