SERVICE /DISTRIBUTOR ? VERSION icon series 3 Introduction The information presented in this section of the man

9、ual is intended for competent technical personnel to carry out service and product support for the icon series. We assume that the reader is familiar with the related electronic theory and audio terminology, and is able to carry out basic servicing, fault-finding and repair of digital audio equipmen

10、t of this type. Service personnel should also be familiar with audio systems, mains earthing and power requirements, as well as handling precautions. For information on the installation, operation and application of the icon series please refer to the User Guide. Whilst we believe the information in

11、 this manual to be reliable we do not assume responsibility for inaccuracies. We also reserve the right to make changes in the interest of further product development. Service and Technical Support Under normal operating conditions the icon does not require user maintenance or internal calibration.

12、Any service work required should be carried out by qualified technical personnel only. We are able to offer further product support through our world-wide distribution network. To help us provide an efficient service please quote the unit serial number, the date and place of purchase in any communic

13、ation regarding this product. SAFETY WARNING! Mains electricity is dangerous and can kill. Mains voltage is present within the console power supply unit. The internal power supply unit contains no serviceable components and must be replaced as a complete unit if a failure occurs. Do not remove the p

14、ower supply cover with mains electricity connected. To ensure your safety, mains earth is connected to the chassis through the power lead. Do not remove this mains earth connection. To avoid the risk of fire, replace the mains fuse only with the correct value and type as indicated on the power suppl

15、y unit. IMPORTANT STATIC ELECTRICITY PRECAUTIONS Many of the components in the icon are extremely sensitive to static electricity. The following procedures reduce the possibility of damaging components: 1) Before handling any components or touching anything inside the unit, discharge your bodys stat

16、ic electric charge by touching a grounded (earthed) surface. Wear a grounding wrist strap if one is available. 2) Do not remove parts from their antistatic containers or bags until you are ready to install them. When removing circuit boards (PCBs) or ICs from a unit, immediately place them in an ant

17、istatic bag. 3) When handling PCBs, hold them by their edges and avoid touching the circuitry. 4) Do not slide PCBs or ICs over any surface. 5) Avoid having plastic, vinyl and foam in your work area. 6) Limiting your movements during service work reduces static electricity. Replace the battery with

18、an Allen & Heath recommended part. Using a different battery, recharging or disassembling the battery may present a danger due to fire or explosion. Dispose of used batteries promptly according to the manufacturers instructions. Keep all batteries away from children. WARNING: There is danger of expl
