HEAD selector
Selects the playback head of the video signal.
R/P: Playback with the R/P (record/playback)
head.
PLAY: Playback with the PLAY head. VTRs equipped
with the dynamic tracking function can
perform dynamic tracking playback.
In the REC or EDIT REC mode, the R/P head is
selected automatically for recording and edit-recording
regardless of the position of this switch.
This selector functions only on the BVH-2000(02).
On the BVH-2000(OO), the head always operates
at any position.
®
TIME CODE/TIMER selector
This switch selects one of the following three kinds of
tape run time display on the display
®.
TIME CODE: This is used to indicate the SMPTE
time code. The CH3 INPUT switch on
the AE-03 board (refer to 1-6-3.)
should be set to the TC position. The
A-3 SEL switch on the AE-03 board is
used to select an external time code or
internal time code (when the optional
BKH-20 15 circuit board is installed).
The TC/U-BIT switch on the BKH-2015
(TC-14) circuit board is used to change
over the time code or user bit indicator.
Normally this indicates a value read by
the time code reader but when the
TAPE / EE selector
CD
is set to INPUT,
it indicates an input from the time
code generator.
TIMER-I: This is used to indicate the tape run
time by counting the CTL signal on
the tape. It is possible to zero reset at
any position on the tape with the
RESET button
(j).
After reset, the
new tape run time is indicated from
this point.
TIMER-2: This is used to indicate the tape run
time by counting the CTL signal on
the tape. When the tape is threaded,
zero reset of the TIMER-2 cannot be
performed.
The data of the TIME TIMER-1 or TIMER-2
selected by this switch, which is indicated on the display,
can be entered as the preroll point.
• Both TIMER-l and 2 start counting the tape run
time when the machine is in an mode except the
STOP mode. The TIMER-2 zero point is the position
where the operation mode is designated after the
tape has been threaded. For TIMER-I, it is possible
to zero reset any position on the tape.
• When the power is turned OFF with the tape install-
ed, the data of TIMER-1 and 2 is retained for 12
hours by means of a built-in back-up capacitor, so
that the data can be used again within this period.

(1) TIMER-l reset
After the TIME selector has been
set to TIMER-I, by pressing the RESET button at

®
can be reset to zero. For TIMER-2, zero
reset cannot be operated.
TIME CODE reset
After the TIME CODE/TIMER selector is set to
TIME CODE, by setting the TAPE/EE selector
CD
to INPUT, the input from the time code
generator is indicated on the display. The time
code generator is reset to zero by pressing the
RESET button in this state.
When the user bit is displayed, the user bit is reset
to zero.
