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.

 This apparatus shall not be exposed to dripping or splashing, and no

object filled with liquids, such as vases, shall be placed on the apparatus.

16.

 This apparatus has been designed with Class-I construction and

must be connected to a mains socket outlet with a protective earthing
connection (the third grounding prong).

17.

 This apparatus has been equipped with an all-pole, rocker-style AC

mains power switch. This switch is located on the rear panel and should
remain readily accessible to the user.

18.

 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.

19.

 Exposure to extremely high noise levels may cause permanent

hearing loss. Individuals vary considerably in susceptibility to noise-induced
hearing loss, but nearly everyone will lose some hearing if exposed to
sufficiently intense noise for a period of time. The U.S. Government’s
Occupational Safety and Health Administration (OSHA) has specified the
permissible noise level exposures shown in the following chart.

According to OSHA, any exposure in excess of these permissible limits
could result in some hearing loss. To ensure against potentially
dangerous exposure to high sound pressure levels, it is recommended
that all persons exposed to equipment capable of producing high sound
pressure levels use hearing protectors while the equipment is in
operation. Ear plugs or protectors in the ear canals or over the ears must
be worn when operating the equipment in order to prevent permanent
hearing loss if exposure is in excess of the limits set forth here.

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.

6.

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.

particularly at plugs, convenience receptacles, and the point where they
exit from the apparatus.

11.

 Only use attachments/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.
