Operating instructions

SECTION 9 Exploded Views and Parts Lists: This section of the manual
contains assembly drawings of the machine "exploded" to show internal parts
and hardware, and the order of assembly. Each exploded view is keyed to an
accompanying parts list showing Otari part numbers and descriptions for all
mechanical components.
1.2.2 Conventions Within This Manual
PCB Assemblies: The term PCB Assembly is used in this manual to refer to
a printed circuit board which has components (resistors, connectors, etc.)
mounted on it. The term PCB or Printed Circuit Board when used alone
refers to the "bare" printed circuit board without components. The term PCB
is rarely used outside of the electrical and mechanical parts lists. When a
PCB Assembly is referred to in the text, the name or function of that PCB
Assembly will usually be given in ALL CAPITAL letters.
ALL UPPER CASE: Generally, this manual uses all upper case type to
describe a switch or control when that item is similarly labeled on the
machine (e.g., the PLAY button).
First Letter: Where a switch or button is not Upper Case labeled or the
reference is unclear, only the first letter of the item is capitalized (e.g., the
Cue Wheel near the CUE button). Machine status or operating modes are
described with an upper case first letter (e.g., you press the PLAY button to
place the machine in Play mode).
( ), [ ] - Normal parentheses ( ) are used for examples and parenthetic
comments. Square brackets [ ] are used to refer to certain illustrations.
When used in text, the square brackets are either references to the same
figure as noted in that sub-section (e.g., [3], meaning the part labeled "3" in
the figure noted) or are preceded by the figure number (e.g., Fig. 2-1, [3],
meaning "3" in Figure 2-1).
Although this manual is intended for 1" 8CH, 2" 16CH and 2" 24CH
operations, the following description deals only with 2" 24CH operation.
Please note that all explanations apply to 1" 8CH and 2" 16CH as well, even if
remarks to that effect cannot be found.
We encourage you to read this manual carefully now, and to again review it
after you have had a while to become familiar with the MTR-90III. The more
you know about your machine, the more you can benefit from its many
versatile features.
