Initializing The File System; Initializing The File System Using Tru - Topcon GR-5 Operator's Manual

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 re‐initialize 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 to initialize the file system.

Initializing the File System Using TRU

1. Connect the receiver to a computer and run TRU.
2. Click the File Explorer icon to open the File Explorer screen.
3. On the Files tab, press and hold the right mouse button on the file line.
4. Click Initialize File System.
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.
