Error Messages and
Troubleshooting
If you see the time-of-day on the recorder
screen, the recorder is recording.
Note: If the LCD screen is completely blank,
this means that the recorder is not recording.
An error message will appear when there is a
problem with the recorder. The recorder may
display the following error messages:
Battery LOW:
Battery is running low. When
this message first appears, you will have about 5
days of recording time left on your battery.
Battery FAILURE:
Recording has stopped.
Card Erase ERROR:
An error was found
while attempting to erase the SD Card. This
usually means a defective card.
LEAD LOOSE:
This error will occur when
there is a problem with the patient hook-up. The
problem may be with an electrode, a lead or the
cable that connects the leads to the recorder. The
LEAD LOOSE message will remain on the
screen for about 10 seconds after the problem
has been corrected. This error message can be
turned off in General Settings.
Missing SD Card:
There is no SD Card in the
device. A card is required for Holter recording.
SD Access:
Unable to read the SD Card. This
usually means a defective card.
SD Card is write locked:
Write Lock tab is set
on the SD Card. Unlock Write Lock tab and try
again.
SD Setup Failure:
Failure during write of
patient ID to SD Card. You will need to re-ini-
tialize your card using the LX software.
SD Card Incorrectly erased:
There may be
disallowed files on the SD Card. Remove SD
Card from recorder and use card reader and
Explorer to identify and delete these files. The
only file allowed is flash.dat.
Short recording:
There are some SD Card
types that may draw excessive power, and will
therefore drain the battery prematurely, result-
ing in a short recording. If you purchase cards
from a supplier other than NorthEast Monitor-
ing, it is recommended that you first test the SD
card for a greater amount of time than the
expected use.
Unable to write SD:
An error was found while
attempting to write to the SD Card. This mes-
sage occurs when the card is full. Sometimes
this message will appear when a card is defec-
tive.
Write Timeout error:
This usually means a
defective card.
