SAFETY PRECAUTIONS & IMPORTANT NOTES

1.Check that the rear of the product indicates the correct supply voltage for you area.

2. 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 manufacturer’s 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
