4-1. Overview of Maintenance Mode
Buttons and Switches for Operation
The main buttons and switches related to the operation of maintenance mode are as follows: The ordinary
functions of these buttons and switches and how to use them are described below.
1 Time data display area
The time data display area displays the menu (mode) No., menu title, selection item, status, or data.
The menu (mode) No. or selection item block blinks while the menu (mode) or selection item is
specified (not including the servo menu in the TAPE maintenance mode). For manual adjustment,
the data block blinks. In the state where the tape operation (PB, REC, F FWD, and REW) can be
performed, the time data display area functions as an ordinary time counter.
