You cannot send the following types of screens to a computer.
• The screen that appears while a data communication operation is in progress.
•A screen that appears while a calculation is in progress.
• The screen that appears following the reset operation.
• The low battery message.
• The flashing cursor is not included in the screen image that is sent from the
unit.
• If you send a screen shot of any of the screens that appear during the data
send operation, you will not be able to then use the sent screen to proceed with
the data send operation. You must exit the data send operation that produced
the screen you sent and restart the send operation before you can send addi-
tional data.
•You cannot use 6mm wide tape to print a screen shot of a graph.
7. Data Communications Precautions
Note the following precautions whenever you perform data communications.
•An error occurs whenever you try to send data to a receiving unit that is not yet
standing by to receive data. When this happens, press A to clear the error and
try again, after setting up the receiving unit to receive data.
•An error occurs whenever the receiving unit does not receive any data approxi-
mately six minutes after it is set up to receive data. When this happens, press A
to clear the error.
•An error occurs during data communications if the cable becomes disconnected,
the parameters of the two units do not match, or if any other communications
problem occurs. When this happens, press A to clear the error, then correct the
problem before trying data communications again. If data communications are
interrupted by the A key operation or an error, any data successfully received
up to the interruption will be in the memory of the receiving unit.
•An error occurs if the receiving unit memory becomes full during data communi-
cations. When this happens, press A to clear the error and delete unneeded
data from the receiving unit to make room for the new data, and then try again.
•To send picture (graph) memory data, the receiving unit need 1-kbytes of memory
for use as a work area in addition to the data being received.
