4-6. DATA COMMUNICATIONS PRECAUTIONS
Note the following precautions whenever you perform data communications.
• A TRANSMIT 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
AC
to clear the error and try again, after setting up the receiving
unit to receive data.
• A RECEIVE 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
AC
to clear the error.
• A TRANSMIT ERROR or RECEIVE ERROR occurs during data communications if the cable becomes
disconnected, if the parameters of the two units do not match, or if any other communications problem
occurs. When this happens, press
AC
to clear the error and correct the problem before trying data
communications again. In this case, any data received before the problem occurred is cleared from the
receiving unit's memory.
• A MEMORY FULL operation occurs if the receiving unit memory becomes full during data communications.
When this happens, press
AC
to clear the error and delete unneeded data from the receiving unit to make
room for the new data, and then try again.
