Operating instructions

4.1 Modes of Operation
CAUTION: The reel motor on the MTR-90III supplies a powerful torque force.
When a tape is threaded on the machine, do not touch the reel or tension
arm. When the machine is in Fast Wind mode, exercise caution to keep hair,
clothing, jewelry, fingers, etc., away from the reel. When the operations are
controlled from the Remote Control, precautionary measures are important.
It is imperative that the swing arms are not pressed directly when a tape is
threaded. To shuttle the tape back and forth slowly, do not attempt to move
the reels by hand. Instead, place the transport in Stop mode and turn the top
of the capstan by hand or press the MTR-90III CUE button and move the
adjacent Cue Wheel.
In the following table, mode names in parenthesis indicate that the MTR-90III
must be in the indicated mode before the designated button is pressed. For
example, to enter Unload mode: (Stop) + UNLOAD means the MTR-90III
must be in Stop mode before the UNLOAD button is pressed.
