Initializing the File System
The GR-5 supports a removable SDHC memory card to log raw data
files. The memory card must be initialized before its first use.
Initializing the memory card while in the receiver ensures the card is
formatted to the TPS proprietary file system (TPFS). This file system
allows the receiver to create, store, retrieve, delete, and restore raw
data files.
It is also advisable to reinitialize the memory card periodically (e.g.,
quarterly). This erases any data on the card, checks for bad blocks,
and sets the card up afresh.
The user can use TRU or PC-CDU to initialize the file system.
Initializing the File System Using
TRU
1. Connect the receiver to a computer and run TRU. See
“Connecting the Receiver and a Computer” on page 2-21.
2. Click the

icon to open the
File Explorer
screen.
3. On
Files
tab, press and hold the left mouse button on the file line.
4. Click

.
Initializing the file system of a connected receiver will erase all of the
receiver’s data files. A warning message will appear to confirm the
operation.

options in the receiver, such as the following:
