2-1. 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 Message display area on sub LCD
The sub LCD 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 sub
LCD functions as an ordinary time counter.
There is a menu (mode) that contains insufficient information displayed in the message display area
of sub LCD. Since the information displayed on the LCD monitor is easier to operate and check,
usually use a LCD monitor.
