3.1.4 The EXIT Control Key
The EXIT key behaves as follows:
While editing a menu item’s value, pressing the EXIT key exits the editor and restores
the pointer to the menu item. Note that all values changed during editing are actually
changed, exiting does not undo those changes. Press the EXIT key, while pointing to
any item in a menu, to return to the next higher menu. Press the EXIT key while the
Top Menu is displayed to exit the Menu mode.
3.1.5 The CALL Control Key
Pressing CALL causes the I/O port slot to extend and open the I/O port door. Fully in-
serting a cartridge causes the I/O port slot to retract and close the I/O port door.
Pressing CALL a second time will also retract the I/O port slot and close the door.
3.1.6 The (Daisy) Key and I/O Port Operation
When the Operating Display is visible, the (Daisy) key can be used together with
the (UP), (DOWN), or MENU key to perform any one of three special functions:
+ MENU: Operates the I/O port (same as pressing the CALL control key).
+ : Executes the PARK HIGH command.
This command moves the carriage to the top of its range of motion in the TLS.
+ : Executes the PARK LOW command.
This command moves the carriage to the bottom of its range of motion in the TLS.
