IMPORTANT NOTES
In addition to the items listed under “USING THE UNIT SAFELY” on page 28–34, please read
and observe the following:
Power Supply: Use of Batteries
• Do not use this unit on the same power
circuit with any device that will generate
line noise (such as an electric motor or
variable lighting system).
• The AC adaptor will begin to generate
heat after long hours of consecutive use.
This is normal, and is not a cause for con-
cern.
• Batteries should always be installed or re-
placed before connecting any other de-
vices. This way, you can prevent malfunc-
tion and/or damage to speakers or other
devices.
• A battery was installed in the unit before it
left the factory. The life of this battery may
be limited, however, since its primary pur-
pose was to enable testing.
• Before connecting this unit to other de-
vices, turn off the power to all units. This
will help prevent malfunctions and/or
damage to speakers or other devices.
Placement
• Using the unit near power amplifiers (or
other equipment containing large power
transformers) may induce hum. To allevi-
ate the problem, change the orientation of
this unit; or move it farther away from the
source of interference.
