IMPORTANT NOTES

In addition to the items listed under “USING THE UNIT SAFELY” on p. 25, please read

and observe the following:

Power Supply: Use of Batteries

•Do not use this unit on the same power cir-

cuit 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 concern.

•The use of an AC adaptor is recommended

as the unit’s power consumption is relative-

ly high. Should you prefer to use batteries,

please use the alkaline type.

•Batteries should always be installed or re-

placed before connecting any other devices.

This way, you can prevent malfunction

and/or damage to speakers or other devic-

es.

•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 devices,

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 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
