SAFETY PRECAUTIONS & IMPORTANT NOTES
1. Check that the rear of the product indicates the correct supply voltage for
your 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

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.
CLASS 1 LASER PRODUCT
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 Azur approved parts only.
NOTES 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 by
the 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.
