Cleaning the Cabinet
Clean the cabinet, panels and controls with
a soft cloth slightly moistened with a mild
detergent solution. Do not use any type of
abrasive and, scouring powder or solvent
such as alcohol or benzine.
Cleaning the Head

contamination of the head.
To make the best possible recording and
playback, we recommend cleaning the
head periodically, using the DT-10CL
cleaning cassette (not supplied).

Notes on the cleaning cassette
• The cleaning cassette cannot be used
for recording and  playback.
• Do not clean the head with the cleaning
cassette more than five times over a
short period.
Cleaning the head continuously for a too
long period of time may cause wear to
the head.
• Do not rewind the cleaning cassette
each time you use it.  When the cleaning
cassette tape is taken up completely,
rewind it to the beginning and re-use it.
The cleaning cassette can be used two
hundred times, with 10 seconds of
cleaning each time.
