The lighting flash with the arrowhead within an equilateral triangle is intended to alert the user or service agent to the presence of dangerous voltages within the product enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. 3. The exclamation point within an equilateral triangle is intended to alert the user or service agent to the presence of important operating and maintenance (Servicing) instructions in the literature accompanying the appliance. 4. This product complies with EEC Low Voltage (73/23/EEC) and Electromagnetic Compatibility (89/336/EEC) Directives when used and serviced in accordance with this manual. For continued compliance all components marked safety and EMC critical must only be replaced by Cambridge Audio approved parts. 5. Any unauthorised design alterations or additions will void the manufacturers warranty; furthermore the manufacturer cannot accept responsibility for personal injury or property damage resulting therefrom. 6. When servicing, care should be taken to observe the original routing and dressing of the leads and it should be confirmed that they have been returned to normal after re-assembly. Notes on chip component replacement Never reuse a component that has been removed from a PCB Notice that the minus side of a tantalum capacitor may be damaged by heat COPYRIGHT NOTICE.

LASER SAFETY PRECAUTIONS Caution: These labels may be attached to the unit on the rear and inside to inform that it contains a laser component. Use of controls or adjustments, or performance of procedures other than those specified within the service or instruction manual may result in hazardous radiation exposure. WARNING! WARNING! 1. Service should only be performed by qualified personnel. 2. This equipment has been designed and manufactured to meet international safety standards; it is the legal responsibility of the repairer to ensure that these safety standards are maintained. 3. Any repairs must be made in accordance with the relevant safety standards. 4. It is essential that safety and EMC critical components are replaced with Cambridge Audio approved parts only. CLASS 1 LASER PRODUCTNOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electrostatic breakdown because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic breakdown and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care. NOTES ON LASER DIODE EMISSION CHECK The laser beam on this model is concerated so as to be focused on the disc reflective surface bythe objective lens in the optical pick-up block. Therefore, when checking the laser diode emission, observe from more than 30cm away from the objective lens. 1261551649318191020137211111422217CDRAWING NOTES:-REVISIONS NOTES:-DATEEDITORREVTHIRD ANGLEPROJECTIONBAABCD123E-MAIL simon.freethaudiopartnershipFINISH:MATERIAL:REVISIONS & DATEE-MAIL nickaudiopartnership1:5SCALE:E-MAIL grahameaudiopartnershipFAX: 0207 940 22331DO NOT SCALE FROM DRAWINGDWG.
