Correcting the input time code using the
instant chase lock function
This unit cannot read a time code input at less than
1/16 times normal speed. Thus, the time code of the
precise start point found by the master unit may differ
from that displayed on the unit. In such a case, the
unit cannot calculate the correct chase offset value.
This instant chase lock function allows the unit to
correct the input time code. When you want to make a
correction, follow the procedure below.
Note
Perform the following operation when "EXT TIME
CODE" flashes in the DISPLAY key menu display
area. This indicates that the time code is not input
because the connected VTR has stopped or is in still
mode.
1
Press the DISPLAY key and set the display to
"EXT TIME CODE."
2
Press the MENU key.
The "H" digits flash. Every time you press the
MENU key, the selected (flashing) character is
shifted one position to the right.
3
To set the value of the flashing digit, turn the
search dial while holding down the DATA key.
Repeat step 2 and 3 to set the remaining digits.
4
Press the SET key to store the time code.
All digits flash.
The unit performs the instant chase lock using this
set time code.

To clear the set value
Press the RESET key while holding down the DATA
key. The set value is cleared and the input time code is
displayed in the time code indication area.
Selecting the chase modes
This unit has the following three kinds of chase modes.
Using the setup menu, you can choose one of them.
• "on-1"(ON-1): In this mode, the unit always runs in
chase mode. However, when the time code on the
tape is not synchronized with the input time code
or when the time code is missed, the unit plays
back at variable speed within +/–0.2% after
locking.
• "on-2"(ON-2): In this mode, the unit always runs in
chase mode. Once it has synchronized with the
external time code, however, the unit enters
normal playback mode. Select this mode to
record after chase synchronization while
rechasing.
• "OFF": The unit releases chase synchronization
once it has synchronized with the external time
code, then enters normal playback mode.
See section 7-3 "Dial Menu Operations" (page 7-5).
Selecting the timing of sound output when
chasing
You can select the timing of sound output for chase
synchronization from the following using "cHASE-Au
(CHASE AUDIO)" of the setup menu:
• When the unit enters the playback mode. (With this
setting, you can hear the sound in variable-speed
playback.) Factory set at this position.
• When the unit locks to the incoming external time
code. (With this setting, you cannot hear the sound in
variable-speed playback.)
See section 7-3 "Dial Menu Operations" (page 7-5).
