Troubleshooting
if not a single satellite is received during this time, then
your raw data file will be empty.
2. If the problem is not yet resolved , go to step 2.
Step 2. Is the
Currently Selected
Memory Usable?
The receiver logs raw data to the internal memory
(recommended) or to a USB stick. With the default settings,
the selected memory is the internal memory. Changing the
storage medium can only be made through $PASH,MEM or
using FAST Survey. You can determine which memory is
currently selected by reading the memory screens. The “*”
symbol indicates the currently selected storage medium.
If the USB stick is the currently selected memory, there is no
USB stick connected and you are using the receiver without
FAST Survey, then the receiver won’t start data logging when
you press the Log button.
1. If you are using the receiver alone and the currently
selected memory is the USB stick, do one of the following:
• Connect a USB stick to the receiver through the USB
device cable provided and press the Log button again.
• Restore the default settings (by pressing the
Log+Power buttons simultaneously) in order to
make the internal memory the active memory. Press
the Log button again.
If neither of these two actions resolves your problem, go to
step 3.
2. If you are using FAST Survey to control the receiver , select
the
Survey
menu. Tap on the
Log Raw GPS
button and then
on the
File Manager
button. Select the memory where you
want the raw data file to be created (Internal Mem or USB
Mem Stick). Come back to the previous screen and tap on
the
Start File
button. If the problem is not yet resolved, go
to step 3.
Step 3. Is the
Currently Used
Memory Full?
Data logging will stop automatically or won’t start if the
storage medium used (internal memory or USB stick) is full.
On the General Status screen, read the remaining percentage
of free memory (second line, last number in the line).
1. If “0%” is displayed , then the memory used is full. Do one
of the following:
• Change the storage medium
• Using $PASHS,FIL,D or FAST Survey, empty the
memory or delete the files you don’t need anymore.
