WARNING: The triangle with the lightning flash symbol displayed on the unit advises the user of dangerous uninsulated
voltage inside the product’s enclosure.
CAUTION: To reduce the risk of electric shock, do not remove the cover. There are no user-serviceable parts inside; it is
recommended that only qualified personnel service this component.
ALERT: The triangle with the exclamation point symbol on the component suggests that the owner refer to important
operating and maintenance instructions in the owner’s manual.
1. OWNER’S MANUAL: Before powering up the equipment, read all safety and operating instructions and follow
them as instructed. Retain the safety and operating instructions for future reference.
2. ATTACHMENTS: Use only those attachments recommended by the unit manufacturer, as others may cause
hazards.
3. ACCESSORIES: Do not place the unit on an unstable cart, stand, tripod, bracket, or table. The unit may fall, causing
injury to a person or damage to the unit. Mount the unit according to the manufacturer’s instructions with the
suggested mounting accessory.
4. WALL OR CEILING MOUNTING: Mount the unit to a wall or ceiling only in the manner recommended by the
manufacturer.
5. WATER AND MOISTURE: Do not use the unit near water (for example, near a swimming pool, bath tub, wash
bowl, kitchen sink, or laundry tub) or in a damp environment (like a basement or outside in the rain).
6. OBJECT AND LIQUID ENTRY: Do not push objects of any kind into the unit through openings as they could
touch dangerous voltage points and short-out parts, possibly resulting in a fire or electric shock. Avoid spilling liquid
of any kind on the unit. If water or any metal object (such as a paper clip, coin, or staple) accidentally falls inside the
unit, disconnect it from the AC power source immediately and contact Cary Audio Design for further instructions.
7. HEAT: Position the unit away from heat sources such as radiators, heat registers, stoves, or other units (including
amplifiers) that produce heat.
8. VENTILATION: Slots and openings in the cabinet create ventilation to protect the component from overheating.
These openings on the top and bottom panels must remain unobstructed. Allow at least six inches (16 cm.) of
clearance above the unit and an opening behind the unit for airflow. Do not place the unit on a bed, sofa, rug, built-in
bookcase, or rack without adequate ventilation.
9. GROUNDING OR POLARIZATION: As a safety feature, the unit may be equipped with a polarized alternating
current line plug in which one blade is wider than the other. This plug will fit into the power outlet only one way. If
you cannot insert the plug fully into the outlet, try reversing the plug. If the plug still will not fit, contact a licensed
electrician to update your obsolete outlet. Do not defeat the safety purpose of the polarized plug.
10. POWER SOURCES: Operate the unit only from the power source indicated on the marking label. If you are unsure
of the type of power supplied to your home, consult your unit dealer or local power company.
11. POWER CORD PROTECTION: Arrange power supply cords so that they do not suffer from foot traffic or
pinching by items placed on or against them. Pay close attention to cords where plugs enter the AC outlet and where
they exit from the unit.
12. LIGHTNING: For added protection during a lightning storm or when the component is idle for long periods of time,
unplug the unit from the wall outlet and disconnect the antenna or cable system. This will help protect the unit from
lightning and power line surge damage.
13. POWER LINES: Do not locate an outside antenna system in the vicinity of overhead power lines or other electric
light or power circuits. When installing an outside antenna system, take extreme care to avoid touching the power
lines or circuits; contact with them could be fatal.
14. OVERLOADING: Do not overload wall outlets, extension cords, or integral convenience receptacles as this
increases the risk of fire or electric shock.

15. REPLACEMENT PARTS: When replacement parts are required, be sure the service technician has used
replacement parts specified by the manufacturer or those having the same characteristics as the original parts.
Unauthorized substitutions may result in fire, electric shock or other hazards.
16. SAFETY CHECK: Upon completion of any service or repairs to the unit, ask the service technician to perform
safety checks to ensure the unit is in proper operating condition.
17. IMPORTANT SAFETY NOTE:
• Before connecting a new product such as the Cary Audio Design MS-1
turn off all other equipment (preferably unplugging them from the AC power source). Many audio components
feature automatic turn-on circuits that may activate during an installation, potentially causing damage to
electronic components or speakers. This type of damage is not covered by product warranties, and Cary Audio
Design specifically disclaims responsibility for any such damage.
• Power Cord: The removable power cord provided with your player was specifically
designed for use with this product, but other AC cords may be used. Consult your dealer
for advice on AC power cords and high quality wire in your system.
• AC Fuse: The fuse is located inside the chassis and is not user serviceable. If the unit does not power up, contact
an authorized service representative.
• Wiring: Cables running inside walls should have the appropriate markings to indicate compliance and listing by
the UL, CSA or other standards required by the UL, CSA, NEC, or your local building code. Questions about
cables inside of walls should be directed to a qualified custom installer, licensed electrician, or low-voltage
contractor.
18. RECORDING COPYRIGHT: Recording of copyrighted material for other than personal use is illegal without
permission of the copyright holder.
19. NOTE TO CATV SYSTEM INSTALLER: This reminder is provided to call the CATV system installer's attention
to article 820-40 of the NEC, ANSI/NFPA 70, which provides guidelines for proper grounding and, in particular,
specifies that the cable ground shall be connected to the grounding system of the building as close to the point of
cable entry as practical.
20. FCC INFORMATION FOR USER:
• CAUTION: Any changes or modifications not expressly approved by Cary
Audio Design could void the user's authority to operate the equipment.
• NOTE: This equipment has been tested and found to comply with the
limits for a Class B digital device pursuant to Part 15 of the FCC Rules.
• These limits are designed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates and can radiate radio frequency energy, and if not installed and used in
accordance with the instructions it may cause harmful interference to radio communications. However, there is
no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from where the receiver is connected.
21. OUTDOOR ANTENNA INSTALLATION/SAFE ANTENNA AND CABLE CONNECTION:
• If an outside antenna or cable system is connected to the
equipment, be sure the antenna or cable system is grounded in
order to provide protection against built-up static charges and
voltage surges. Article 810 of the National Electrical Code,
ANSI/NFPA 70 (in Canada, Part 1 of the Canadian Electrical
Code) provides information regarding proper grounding of the
mast and supporting structure, grounding of the lead-in wire to an
antenna discharge unit, size of grounding conductors, location of
antenna discharge unit, connection to grounding electrodes and
requirements for the grounding electrode.
outside antenna system should be located well away from power lines,
electric light or power circuits and where it will never come into contact with these power sources if it should happen to
fall. When installing an outside antenna, take extreme care to avoid touching power lines, circuits and other power sources
as this could be fatal. Because of the hazards involved, antenna installation should be left to a professional.
