This logo will be quickly followed by a message stating “Initializing SD
Card”. This indicates that the recorder has recognized the card and has
gone through the initial SD card set-up.
(Note: If the 300-4L recorder does not detect the presence of an SD card
once the battery is inserted, the following error message will be
displayed.)
(Note: It is very important that a NEW AAA battery is used for each
individual test in order to minimize the likelihood of missing or incomplete
ECG recording data. To this end, the 300-4L Holter recorder will provide
two different types of warning messages when it detects a low battery.
The first type of warning is for batteries that still have sufficient battery life
for a short Holter recording. You will have the option to continue. The
second warning is for batteries that are detected to be nearly depleted. In
this case, you will not be able to proceed until the battery is replaced with
a new one.)
