Overwrite mode and insert mode
• Pressing

mode (default); and insert mode. A rectangular cursor indicates preexisting
data will be overwritten as you make entries, while a triangular cursor
indicates that an entry will be inserted at the cursor.
• In the overwrite mode, data under the cursor will be overwritten by the
number you enter. To insert a number in the insert mode, move the cursor
to the place immediately after where you wish to insert, then make the
desired entry.
• The mode set will be retained until
@ O
is pressed or a RESET
operation is performed.
