CAUTION

CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK,
DO NOT REMOVE COVER. NO USER-SERVICEABLE PARTS
INSIDE. REFER SERVICING TO QUALIFIED SERVICE
PERSONNEL.

The lightning flash with arrowhead symbol, within an
equilateral triangle, is intended to alert the user to the
presence of uninsulated “dangerous voltage” within the
product’s enclosure that may be of sufficient magnitude
to constitute a risk of electric shock to persons.

The exclamation point within an equilateral triangle is
intended to alert the user to the presence of important
operating and maintenance (servicing) instructions in
the literature accompanying the appliance.

WARNING: TO AVOID FIRE OR ELECTRIC

SHOCK HAZARD, DO NOT EXPOSE THIS

APPARATUS TO WATER, RAIN OR MOISTURE.

Important Safety Information

Important Safety Instructions

1. Read these instructions.

2. Keep these instructions.

3. Heed all warnings.

4. Follow all instructions.

5. Do not use this apparatus near water. Do not expose to

drips or splashes. Do not place any objects filled with
liquids, such as vases, on the apparatus.

6. Clean only with dry cloth.

7. Do not block any ventilation openings. Do not install this

apparatus in a confined space such as a book case or
similar unit. Install only in racks designed for the purpose
and in accordance with manufacturers’ instructions.

8. Do not install near any heat sources such as radiators,
heat registers, stoves, or other apparatus (including
amplifiers) that produce heat.

9. Do not defeat the safety purpose of the polarized or
grounding-type plug. A polarized plug has two blades with
one wider than the other. A grounding-type plug has two
blades and a third grounding prong. The wide blade or the
third prong are provided for your safety. If the provided
plug does not fit into your outlet, consult an electrician for
replacement of the obsolete outlet.

10. Protect the power cord from being walked on or
pinched particularly at plugs, convenience receptacles,
and the point where they exit from the apparatus.

11. Only use attachments and accessories specified by
the manufacturer.

12. Use only with a cart, stand, tripod, bracket, or table
specified by the manufacturer, or sold with the apparatus.
When a cart is used, use caution when moving the
cart/apparatus combination to avoid injury from tip-over.

13. Unplug this apparatus during lightning storms or when
unused for long periods of time.

14. Refer all servicing to qualified service personnel.
Servicing is required when the apparatus has been
damaged in any way, such as power-supply cord or plug
is damaged, liquid has been spilled or objects have fallen
into the apparatus, the apparatus has been exposed to
rain or moisture, does not operate normally, or has been
dropped.

15. Apparatus designed with Class-I construction must be
connected to a mains socket outlet with a protective
earthing connection (the third grounding prong).

16. This apparatus may be equipped with a single-pole,
rocker-style AC mains power switch. If so this switch is
located on the front panel and should remain readily
accessible to the user.

17. The manufacturer reserves the right to change the
technical specification of the product without prior notice.

NOTE — This apparatus does not exceed the Class
A/Class B (whichever is applicable) limits for radio noise
emissions from digital apparatus as set out in the radio
interference regulations of the Canadian Department of
Communications.

.

ATTENTION — Le présent appareil numérique n’émet
pas de bruits radioélectriques dépassant las limites
applicables aux appareils numériques de class A/de class
B (selon le cas) prescrites dans le réglement sur le
brouillage radioélectrique édicté par les ministere des
communications du Canada.

These limits are designed to provide reasonable
protection against harmful interference in a
commercial/residential installation respectively. This
equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in
accordance with the instruction manual, may cause
harmful interference to radio communications. There is
no guarantee that interference will not occur in a particular
installation. If this equipment does cause interference to
radio or television equipment reception, which can be
determined by turning the equipment off and on, the user
is encouraged to try to correct the interference by any
combination of the following measures: (1) Relocate or
reorient the receiving antenna (2) Increase the separation
between the equipment and the receiver (3) Plug the
equipment into an outlet on a circuit different from that to
which the receiver is connected (4) Consult your dealer or
experienced radio/television technician for additional
assistance.

CAUTION — Changes or modifications to this equipment
not expressly approved by the party responsible for
compliance could void the user's authority to operate this
equipment.

Statement of WEEE Policy

PMI Audio Group manufactures many complete
electronic products which are covered by the European
Union’s “Waste Electric and Electronic Equipment”
directive 2002/96/EC (WEEE). This directive seeks to
ensure that waste electric and electronic equipment is
disposed of in an environmentally responsible manner, at
the end of its life cycle. PMI Audio Group takes seriously
its obligations under this directive to take back WEEE­affected products and, from 13th August 2005, will mark
all such products with the crossed-out wheeled bin
symbol.

Business to Business products: PMI Audio Group will
cost-neutrally take back WEEE-affected electric and
electronic equipment in this category, from 1st January

2006. PMI Audio Group will work with disposal and
recycling partners working within the EU. The waste
electric and electronic equipment can then be turned over
to a disposal and recycling companies in the countries
concerned.

Business to Customer products: emerging electric and
electronic equipment will be disposed of by local
authorities' collection systems.

Dual Use products: this equipment will be disposed of by
local authorities' collection systems.

Statement of RoHS Compliance

PMI Audio Group manufactures complete electronic
products which are covered by the European Union’s
“Removal of Hazardous Substances” directive
2002/95/EC (RoHS). This directive seeks to eliminate
toxic substances from the manufacturing process, such
that when equipment is disposed of at the end of its life
cycle, the materials it contains do not contaminate the
environment and pose health risks. Banned substances
are lead, mercury, cadmium, hexavalent chromium,
polybrominated biphenyls (PBB) and poly-brominated
diphenyl ethers (PBDE). Lead is used together with tin in
solder connections to reduce the melting point of solder.
Lead-free solder requires higher soldering temperatures
which in turn places greater thermal stress on
components.

PMI Audio Group takes seriously its obligations under the
RoHS directive and insists that its factories use only
components that are certified RoHS compliant, as well as
lead-free solder. In a very few cases the necessary
components may not yet be available to the world market
but we work continuously to eliminate any such
exceptions at the earliest opportunity. Our printed Circuit
Boards (PCB’s) and all soldered joints have been lead­free since 2005.
