Operating instructions

4.3 Auto Locator Operation
The OTARI CB-148 Auto Locator is designed specifically for the MTR-90III. It
uses a microcomputer for sophisticated, precision control of tape motion
without overshoot. The tape time memory stores up to 10 cue points (11 if
search zero is also considered) which can be directly memorized by pressing
only one button instead of being keyed in and can be directly recalled
instantly by pressing another button. And there is an independent digital
built in stop-watch. Each memory and readout can accommodate times of
up to 9H59M59S. In addition to special Auto Locator functions such as
Search, Search Zero, Zero Set, Shuttle and Auto Rewind (described in
subsequent paragraphs), there is a duplicate set of tape transport control
buttons like those on the Remote Control Unit and transport. The CB-148
Auto Locator should be installed as detailed in § 2.3 and § 2.4. The front
panel features of the Auto Locator are briefly described in § 3.3.
4.3.1 Entering Locate Times
The Locate Time readout displays the tape time to be located when the
SEARCH, SHUTTLE or AUTO REWIND buttons are pressed. There are 3 ways
to enter Locate times:
❑ Locate times can be entered directly from the 10-Key pad. Negative
locate times can be entered with the +/- button.
❑ Locate times can be recalled from stored tape locations or cues (see
§ 4.3.3).
❑ Locate time can be "copied" from the Tape Time readout by pressing the
SHIFT RIGHT button.
NOTE: It is impossible to enter a locate time with a numeral of 6 or higher in
the tens digit for minutes or seconds.
4.3.2 Storing Cue Points
There are two ways to store cue points into the Auto Locator memory. Both
methods store the tape time displayed on the Locate Time readout and not
the time on the Tape Time readout.
❑ Storing with the STORE 0-9 Buttons (Direct Store): The tape time can
be directly stored in memory without using the 10-Key Pad. Up to ten
memories can be stored just by pressing a button with an dark indicator.
1. To store a given cue, display the desired cue point time in the Locate
Time readout (refer to § 4.3.1).
2. Press a STORE 0-9 button with an dark indicator. The number pressed
(0 through 9) becomes the "address" where the Locate Time is stored. If
an indicator is illuminated, a tape location has already been stored in that
memory and that STORE 0-9 button is inoperable.
3. To store a second cue, repeat Steps 1 and 2 using a different address.
The same address or the address of a memory with a tape location
stored cannot be used.
NOTE: To use this method when an address already has a tape time stored,
the memory must first be erased before proceeding.
