RISK OF ELECTRIC SHOCK

DO NOT OPEN

TO PREVENT ELECTRIC SHOCK, MATCH

WIDE BLADE OF PLUG TO WIDE SLOT,

FULLY INSERT.

POUR ÉVITER LES CHOCS ÉLECTRIQUES,

INTRODUIRE LA LAME LA PLUS LARGE DE

LA FICHE DANS LA BORNE CORRE-

SPONDANTE DE LA PRISE ET POUSSER

JUSQU' AU FOND.

CAUTION:

ATTENTION:

The exclamation point within an equilateral

triangle is intended to alert the user to the

presence of important operating and mainte-

nance (servicing) instructions in the literature

accompanying the appliance.

The lightening 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 en-

closure that may be of sufficient magnitude to

constitute a risk of electric shock to persons.

“WARNING”

“TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO

NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE.”

CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK,

DO NOT REMOVE COVER (OR BACK).

NO USER-SERVICEABLE PARTS INSIDE.

REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.

1. Read instructions - All the safety and operating instructions

should be read before the appliance is operated.

2. Retain instructions - The safety and operating instructions

should be retained for future reference.

3. Heed warnings - All warnings on the appliance and in the

operating instructions should be adhered to.

4. Follow instructions - All operating and use instructions

should be followed.

5. Water and Moisture - The appliance should not be used near

water - for example, near a bathtub, washbowl, kitchen sink,

laundry tub, in a wet basement, or near a swimming pool,

and the like.

6. Carts and Stands - The appliance should be used only with a

cart or stand that is recommended by the manufacturer.

An appliance and cart combination should be moved with

care. Quick stops, excessive force, and uneven surfaces

may cause the appliance and cart combination to overturn.

7. Wall or Ceiling Mounting - The appliance should be mounted

to a wall or ceiling only as recommended by the manufac-

turer.

8. Ventilation - The appliance should be situated so that its lo-

cation or position does not interfere with its proper ventila-

tion. For example, the appliance should not be situated on a

bed, sofa, rug, or similar surface that may block the ventila-

tion openings; or, placed in a built-in installation, such as a

bookcase or cabinet that may impede the flow of air through

the ventilation openings.

9. Heat - The appliance should be situated away from heat

sources such as radiators, heat registers, stoves, or other ap-

pliances (including amplifiers) that produce heat.

10. Power Sources - The appliance should be connected to a

power supply only of the type described in the operating in-

structions or as marked on the appliance.

11. Grounding or Polarization - The precautions that should be

taken so that the grounding or polarization means of an appli-

ance is not defeated.

12. Power Cord Protection - Power supply cords should be routed

so that they are not likely to be walked on or pinched by items

placed upon or against them, paying particular attention to

cords at plugs, convenience receptacles, and the point where

they exit from the appliance.

13. Cleaning - The appliance should be cleaned only as recom-

mended by the manufacturer.

14. Nonuse Periods - The power cord of the appliance should be

unplugged from the outlet when left unused for a long period

of time.

15. Object and Liquid Entry - Care should be taken so that objects

do not fall and liquids are not spilled into the enclosure

through openings.

16. Damage requiring Service - The appliance should be serviced

by qualified service personnel when:

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

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

appliance; or

C. The appliance has been exposed to rain; or

D. The appliance does not appear to operate normally or

exhibits a marked changed in performance; or

E. The appliance has been dropped, or the enclosure dam-

aged.

17 Servicing - The user should not attempt to service the appli-

ance beyond that described in the operating instructions. All

other servicing should be referred to qualified service personnel.

3-2 Battery Check

While holding down the EXIT key and ENTER key together, press the EFFECT PARAMETER key.

· The LCD Display will show the voltage of the memory backup battery inside theVM04 for

a second, and then return to the Normal Mix mode.

· If the voltage falls below 2.2V, the message “BattEmpty” will appear when powering ON.

· If the message “BattEmpty” is displayed, please replace the battery with the new one. For

exchanging procedure, please refer to the page 7.

3-6 Memory Clear

While holding down the EXIT key and ENTER key together, press the SCENE STORE key

· Pressing the ENTER key would clear the memory and the message “ClearMem!”

appear. All the setup will be initialized.

· Pressing the key other than ENTER returns to the Normal Mix mode display (The

Scene No. 00 is displayed.) and the memory will not be initialized.

· Pressing the RESET SW would also clear the memory and the message “ClearMem!”

appear.

Gain Table

The value appears in the LCD display corresponds

to the gain in dB as shown below.

REPLACING THE BATTERY

If the voltage of the inside memory backup battery falls below 2.2V,

the message “BattEmpty” will appear when powering ON.

CAUTION

· Replacing the battery with the new one would basically

initialize the backup data.

· In order to retain the backup data, please replace the

battery while powering on.
