1. SAFETY INSTRUCTIONS

1.

Read Instructions — Read all the safety and operation instructions before

operating the DX8.

2.

Retain Instructions — The safety and operating instructions should be

kept for future reference.

3.

HEED ALL WARNINGS — Follow all warnings on the DX8 and in these

operating instructions.

4.

FOLLOW ALL INSTRUCTIONS — Follow all operating and other

instructions.

5.

Water and Moisture — Do not use the DX8 near water – for example,

near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement,
near a swimming pool, etc.

6.

Ventilation — This DX8 should be situated so that its location or position

does not interfere with its proper ventilation. For example, it should not be
situated on a bed, sofa, rug, or similar surface that may block any
ventilation openings, or placed in a built-in installation such as a bookcase
or cabinet that may impede the flow of air through ventilation openings.

7.

Heat — Locate the DX8 away from heat sources such as radiators, or

other devices which produce heat.

8.

Power Sources — Connect the DX8 to a power supply only of the type

described in these operation instructions or as marked on the rear panel. If
using an external DC power supply or battery pack, be sure the voltage
corresponds to the range indicated on the rear panel, and that it is
connected with the correct polarity.

9.

Power Cord Protection — Route power supply cords so that they are not

likely to be walked upon or pinched by items placed upon or against them,
paying particular attention to cords at plugs, convenience receptacles, and
the point where they exit the DX8.

10.

Object and Liquid Entry — Do not drop objects into or spill liquids into the

inside of the DX8.

11.

Damage Requiring Service — The DX8 should be serviced only by

qualified service personnel when:

A. The power-supply cord or the plug has been damaged; or

B. Objects have fallen, or liquid has spilled into the DX8; or

C. The DX8 has been exposed to rain; or

D. The DX8 does not appear to operate normally or exhibits a marked
     change in performance; or

E. The DX8 has been dropped, or its chassis damaged.

12.

Servicing — The user should not attempt to service the DX8 beyond those

means described in this operating manual. All other servicing should be
referred to the EAW COMMERCIAL Service Department.

13.

To prevent electric shock, do not use this polarized plug with an extension

cord, receptacle or other outlet unless the blades can be fully inserted to
prevent blade exposure.

Pour préevenir les chocs électriques ne pas utiliser cette fiche polariseé
avec un prolongateur, un prise de courant ou une autre sortie de courant,
sauf si les lames peuvent être insérées à fond sans laisser aucune pariie à
découvert.

14.

Grounding or Polarization — Precautions should be taken so that the

grounding or polarization means of the DX8 is not defeated.

15.

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
règlement sur le brouillage radioélectrique édicté par les ministere des
communications du Canada.

   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.

   Le symbole éclair avec point de flèche à l'intérieur d'un triangle équilatéral est 
utilisé pour alerter l'utilisateur de la présence à l'intérieur du coffret de "voltage 
dangereux" non isolé d'ampleur suffisante pour constituer un risque d'éléctrocution.

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

   Le point d'exclamation à l'intérieur d'un triangle équilatéral est employé pour 
alerter les utilisateurs de la présence d'instructions importantes pour le fonction-
nement et l'entretien (service) dans le livret d'instruction accompagnant l'appareil.
