Precautions Unpacking
On safety
•Should any solid object or liquid fall into the cabinet,
unplug the unit and have it checked by qualified personnel
before operating it any further.
•Unplug the unit from the wall outlet if it will not be used
for a long time. To disconnect the cord, pull it out by
grasping the plug. Never pull the cord itself.
•The unit is not disconnected from the AC power source
(mains) as long as it is connected to the wall outlet, even if
the unit itself has been turned off
On operation
•When the unit is not used, turn the power off to conserve
energy and to extend the useful life of your unit.
• Because of a safety mechanism, the function buttons will
not operate if the cassette holder is not completely closed, if
there is no cassette in the cassette holder, or if a cassette has
been incorrectly inserted into the cassette holder.
On head cleaning
The head and tape path should be cleaned after every ten
hours of operation. Dirty heads and a dirty tape path may
cause:
— loss of high-frequency response
— loss of sound volume
— sound drop-out
Checking the Supplied Accessories
Make sure that the following supplied accessories are
included with your unit.
