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 approximately 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 communications. 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.
