Power Supply
• Do not connect this unit to same electrical outlet
that is being used by an electrical appliance that
is controlled by an inverter or a motor (such as a
refrigerator, washing machine, microwave oven, or
air conditioner). Depending on the way in which
the electrical appliance is used, power supply noise
may cause this unit to malfunction or may produce
audible noise. If it is not practical to use a separate
electrical outlet, connect a power supply noise lter
between this unit and the electrical outlet.
• The AC adaptor will begin to generate heat after long
hours of consecutive use. This is normal, and is not a
cause for concern.
• To prevent malfunction and equipment failure,
always make sure to turn o the power on all your
equipment before you make any connections.
• When using the optional AC adaptor, the DUO-
CAPTURE EX will automatically be switched o after
10 consecutive hours of no communication with the
computer. After the power is automatically switched
o, turn the power o and then on if you want to use
the DUO-CAPTURE EX again.
Power Supply: Use of Batteries
• When installing or replacing batteries, always turn
this unit o and disconnect any other devices you
may have connected. This way, you can prevent
malfunction and damage.
• The life of the supplied batteries may be limited,
since its primary purpose was to enable testing.
• When operating this unit using batteries, please use
alkaline batteries or rechargeable Ni-MH batteries.
• This unit will not operate using batteries or bus
power unless the AC adaptor is disconnected.
• Even if batteries are installed, the unit will turn o
if you connect or disconnect the power cord from
the AC outlet while the unit is turned on, or if you
connect or disconnect the AC adaptor from the unit.
You must turn o the power before you connect or
disconnect the power cord or AC adaptor.
Placement
• Using the unit near power ampliers (or other
equipment containing large power transformers)
may induce hum. To alleviate the problem, change
the orientation of this unit; or move it farther away
from the source of interference.
• This device may interfere with radio and television
reception. Do not use this device in the vicinity of
such receivers.
• Noise may be produced if wireless communications
devices, such as cell phones, are operated in the
vicinity of this unit. Such noise could occur when
receiving or initiating a call, or while conversing.
Should you experience such problems, you should
relocate such wireless devices so they are at a greater
distance from this unit, or switch them o.
• Do not expose the unit to direct sunlight, place
it near devices that radiate heat, leave it inside
an enclosed vehicle, or otherwise subject it to
temperature extremes. Excessive heat can deform or
discolor the unit.
• When moved from one location to another where
the temperature and/or humidity is very dierent,
water droplets (condensation) may form inside
the unit. Damage or malfunction may result if you
attempt to use the unit in this condition. Therefore,
before using the unit, you must allow it to stand for
several hours, until the condensation has completely
evaporated.
• Depending on the material and temperature of the
surface on which you place the unit, its rubber feet
may discolor or mar the surface.
You can place a piece of felt or cloth under the
rubber feet to prevent this from happening. If you
do so, please make sure that the unit will not slip or
move accidentally.

Also, avoid the use of insecticides, perfumes, alcohol,
nail polish, spray cans, etc., near the unit. Swiftly wipe
