304a

• When installing or replacing batteries, always turn 

off the power on this unit and disconnect any other 
devices you may have connected. This way, you can 
prevent malfunction and/or damage to speakers or 
other devices.

306b

• Batteries are supplied with the unit. The life of these 

batteries may be limited, however, since their 
primary purpose was to enable testing.

307

• Before connecting this unit to other devices, turn off 

the power to all units. This will help prevent 
malfunctions and/or damage to speakers or other 
devices.

302

• The AC adaptor will begin to generate heat after long 

hours of consecutive use. This is normal, and is not 
a cause for concern.

301

• Do not connect this unit to same electrical outlet that 

is being used by an electrical appliance that is 
controlled by an inverter (such as a refrigerator, 
washing machine, microwave oven, or air condi-
tioner), or that contains a motor. 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 filter between this unit and the electrical outlet.

303a

• The use of an AC adaptor is recommended as the 

unit’s power consumption is relatively high. Should 
you prefer to use batteries, please use the alkaline 
type.

351

• Using the unit near power amplifiers (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.

352a

• This device may interfere with radio and television 

reception. Do not use this device in the vicinity of 
such receivers.

352b

• 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 off.

354a

• 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 temper-
ature extremes. Excessive heat can deform or 
discolor the unit.

355b

• When moved from one location to another where the 

temperature and/or humidity is very different, 
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.

360

• 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.

401a

• For everyday cleaning wipe the unit with a soft, dry 

cloth or one that has been slightly dampened with 
water. To remove stubborn dirt, use a cloth impreg-
nated with a mild, non-abrasive detergent. After-
wards, be sure to wipe the unit thoroughly with 
a soft, dry cloth.

402

• Never use benzine, thinners, alcohol or solvents of 

any kind, to avoid the possibility of discoloration 
and/or deformation.

553

• Use a reasonable amount of care when using the 

unit’s buttons, sliders, or other controls; and when 
using its jacks and connectors. Rough handling can 
lead to malfunctions.

556

• When connecting / disconnecting all cables, grasp 

the connector itself—never pull on the cable. This 
way you will avoid causing shorts, or damage to the 
cable’s internal elements.

558a

• To avoid disturbing your neighbors, try to keep the 

unit’s volume at reasonable levels. You may prefer to 
use headphones, so you do not need to be concerned 
about those around you (especially when it is late at 
night).

559a

• When you need to transport the unit, package it in 

the box (including padding) that it came in, if 
possible. Otherwise, you will need to use equivalent 
packaging materials.

562

• Some connection cables contain resistors. Do not use 

cables that incorporate resistors for connecting to this 
unit. The use of such cables can cause the sound level 
to be extremely low, or impossible to hear. For infor-
mation on cable specifications, contact the manufac-
turer of the cable.
