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.

3.3Problem Solving

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.
