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

CLASS 1 LASER PRODUCT
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 b
y
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.
