equipment, guidelines are given in the installation instructions, to
enable you to ensure minimum interaction between different
items of equipment, i.e. ensure optimum Electromagnetic Com-
patibility (EMC).
• Always report any EMC-related problem to your nearest Ray-
theon dealer. We use such information to improve our quality
standards.
• In some installations, it may not be possible to prevent the equip-
ment from being affected by external influences. In general this
will not damage the equipment but it can lead to spurious resetting
action, or momentarily may result in faulty operation.
All Raytheon products are subjected to comprehensive test and
quality assurance programmes prior to packing and shipping.
However, if this unit should develop a fault, please refer to the
following table to identify the most likely cause and the corrective
action required to restore normal operation.
If you still have a problem after referring to the table below, contact
your local dealer, national distributor or Raytheon Product Support
Department for further advice.
Always quote the product serial numbers. The display unit serial
number is printed on the back of the unit, and the scanner serial
number is on the back of the scanner near the gland.
