Using the Cursor Keys
Use the large round cursor key located in the upper right corner of the BN Unit’s keyboard whenever
you have to perform any operation that requires movement up, down, left, or right.
In addition to actually moving the input cursor, the cursor key is also used to select menu bar menus
and the commands inside of a menu.
In the User’s Guide, we will use black arrows to indicate which part of the cursor key you should press
to move the cursor in a given direction, even though the cursor key itself is not marked with such
arrows.

Screen Scrolling
Appearance of the or indicator on the left side of the display indicates that data runs
off the top or bottom. The following describes how to scroll data.
• Use the and cursor keys to scroll line-by-line.
• Use the and keys to scroll a page, day, or week at a time.
• Note that with most screens, not all of the contents scroll. Only the portion of the screen that has
multiple lines scrolls (such as the DESCRIPTION field of a SCHEDULER item), while other parts
(such as TIME and DATA fields) remain unchaged.
■
Using the Menu Bar
The menu bar provides you with a selection of pull-down menus containing commands that are very
similar to those found in many desktop computer applications.
The availability of the menu bar, the type of pull-down menus it contains, and the contents of the pull-
down menus depend on the mode you are in and the type of operation you are currently performing.
See the Appendix at the back of the User’s Guide for a full list of commands that appear in each menu.

Make backup copies of important data!
Your BN Unit employs flash memory, which makes it possible to store large volumes of data and to
recall data quickly and easily. Data is retained when power is turned off and even when batteries go
dead, but it can be corrupted or lost entirely due to operational mistakes or malfunction. Data contents
can also be corrupted or lost due to strong electrostatic charge, strong impact, or extremes in tem-
perature and humidity. All of this means that you should always keep back-up copies of important data
by transferring it to a personal computer or by writing it down somewhere.
