, or user-named
numerical lists, or without using menu item

.
Although a transmission error does not occur, these two
conditions may prevent successful transmission:
•
You try to use
Get(
with a calculator instead of a
CBL 2/CBL.
•
You try to use
GetCalc(
with a TI
N
82 or TI
N
83 instead of a
TI
N
73.
Backing Up Memory
The TI
N
73 includes two types of memory: RAM (Random
Access Memory) and F-ROM (Flash Read Only Memory). RAM
includes all lists, programs, variables, and equations. F-ROM
includes software applications, such as the
CBL
à
CBR
application (

).
To copy (and overwrite) the exact contents of RAM in the
sending TI
N
73 to the memory of the receiving TI
N
73, follow
these steps:
1. Set up the receiving unit in receive mode (see page 257).
2. Then, on the sending unit, select
D:Back Up
from the
Link
SEND
menu.
3. Select
1:Transmit
from the
MEMORYBACKUP
menu on the
sending unit to begin transmission. Selecting
2:Quit
returns you to the
Link SEND
menu.
4. As a safety check to prevent accidental loss of memory,
the message
WARNING–BACKUP
is displayed when the
receiving unit receives notice of a backup.
Select
1:Continue
to begin the backup transmission.
Select
2:Quit
to prevent the backup and return to the
Link
SEND
menu.
When the backup is complete, both the sending calculator and
receiving calculator display a
MEMORY BACKUP
confirmation
screen. If a transmission error occurs during a backup, the
receiving unit’s memory is reset.
