• You attempt a data transfer from a TIN73 to a TIN83 with
data other than numerical lists, L1-L6, or user-named
numerical lists, or without using menu item 0:Vars to TI83.
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 TIN82 or TIN83 instead of a
TIN73.
Backing Up Memory
The TIN73 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 CBLàCBR
application (9 2).
To copy (and overwrite) the exact contents of RAM in the
sending TIN73 to the memory of the receiving TIN73, 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.
