To retry the download, press the 1 and ENT keys; to abort it, press the 2 and ENT keys.
To return to the SYSTEM MESSAGE transfer menu, press the C key.
While the downloading operation is in progress, the screen shown at
left is displayed indicating the file name and the number of received
records/the total number of records.
To abort the downloading operation, press the C key. The screen will
switch back to the SYSTEM MESSAGE transfer menu.
Upon completion of downloading, the BHT displays the screen shown
at left and beeps once.
Press the C key to return to the SYSTEM MESSAGE transfer menu.
When the BHT downloads the system message file, it creates a
temporary file named "_B80MSG.FN3" in the user area. If the
user area is insufficient for creating the temporary file, therefore,
an error will result.
The created temporary file will be automatically deleted after
completion of downloading.

downloaded.
Solution
Press the 2 key to return to the SYSTEM MENU, then delete
unnecessary files in the memory. (Refer to Subsection 2.5.3, [ 7 ].)
