Transferring files directly from a CompactFlash card
Data is stored in the internal flash memory. To transfer files between the receiver and
your office computer, connect the receiver to the office computer and use the Data
Transfer utility to transfer files.
When you use the Data Transfer utility to transfer data files from the receiver, the Data
Transfer utility converts the raw receiver data (.T01) files you select into the Trimble
DAT file format.
You can convert receiver data files by using a Windows Explorer extension which is
installed on your computer when you install the Data Transfer utility.
Deleting files in the receiver
You can delete files stored in the receiver at any time. Do one of the following:
• Press E  for 30 seconds after the receiver is turned on. (When you use this
method, all data is deleted.)
