A deck standby mode has been added as a user-optional transport load condition. Place the
M20 in Deck Standby by pressing the Peak Mode and Stop buttons simultaneously. In this
mode, the cassette remains loaded in the transport and the tape is completely withdrawn
into the cassette. When the tape is withdrawn, the drum is turned off and drum hours do
not accumulate. The counter display will indicate “DECK STANDBY” until it is refreshed
by another operation; however, the transport will remain in standby. Pressing any
transport control button (Rew, FFwd, Stop, Play, Rec, Loc, Loc 0,) will first rethread the
tape, then perform the selected transport operation.

Deferred Eject has been added. Pressing Eject when a locate is in progress will defer the
Eject action until the locate is complete. Pressing Eject twice before the locate is completed,
will abort the locate and result in an immediate tape eject.

ID
The M20's RS422 device ID is now a BVW-75 instead of a BVU-950. Many Sony 9-pin
editor/controllers will identify the M20 as this standard Betacam SP videotape recorder.
Changing the ID to the BVW-75 specifically improves performance with AVID’s Media
Composer Version 7.1.

Sample rate can no longer be changed when the tape is in Play or Record. This guarantees
the output of MTC at the proper frequency for the selected sample rate.
