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

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;
or
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.

3-6 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.
