14.1 Head and transport
cleaning
The DA-98 incorporates an internal cleaning
mechanism that not only cleans the rotary head,
but also the tape as it enters the tape path. The pro-
vision of this cleaning mechanism significantly
reduces the need for manual cleaning. If, despite
the internal cleaning mechanism, the
PB CONDI-
TION
indicator (page 2-1) lights, the heads are
dirty and manual cleaning procedures should be
followed.
Use a TEAC HC-8 cleaning tape (recommended)
or a dry cleaning tape specially designed for Hi8
8mm video equipment.
We recommend the following schedule (based on
our experience with the DTRS system) for clean-
ing and maintenance schedules. See 14.1.3,
“Checking head time” below for details of how to
check head usage time.
The above cleaning cycle timings are based on the
assumption that the DA-98 is being operated in a
clean environment. A dusty or smoky atmosphere
will shorten the time between cleaning operations.
14.1.1 To clean the heads and transport
1) Use the cursor keys [25] so that the cursor is by
menu group 9, and then press
ENTER
[27].
If you do not see the screen above, press the
ESCAPE
key [27] until it appears.
2) Within menu group 9, move the cursor so that
it is by

mode to
.
If a tape has already been loaded, it will automati-
cally be ejected.
5) Insert the cleaning tape.
6) The cleaning tape will “play” for about 5
seconds and then be ejected automatically. The
cleaning counter (number of times the heads
have been cleaned) will be incremented by one.
WARNINGS
NEVER use a wet-type cleaning tape, as this will result
in winding problems.
The use of the dry tape will reduce the head life of the
DA-98 by about five hours. Use of manual cleaning is
therefore discouraged.
Every 350 to
400 hours
Perform manual cleaning of heads and
guides as described below. Check the
tape path alignment after cleaning.
This requires proper test and measure-
ment equipment, and should be per-
formed only by qualified service
personnel.
Every 1000
hours (every
third cleaning)
A complete alignment check should be
performed.
NOTE
Most name brand tapes are of very high quality. How-
ever, it is sometimes possible to receive “bad” stock
which exhibits execssive shedding characteristics. If you
receive such tape stock, stop using it immediately, and
follow the cleaning procedure as described below.
