Chapter 13: Link and the CBLàCBR Application 261 • 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.
