Holter Recording: Power Loss Protection Feature
T
he Holter signal is now ready to be ana-
lyzed.
Note: For a DR300, instead of removing
the SD card, you could choose to
wirelessly transmit the recording using a
paired Bluetooth adapter. Refer to the
DR300 Gateway and Socket Technical
Manual, NEMM046, for information on
how to set up and run the wireless feature.
If you are using the USB Bluetooth
adapter, there can be only one paired
adapter in a given location, such as an
office.
Power Loss
Protection Feature
In Holter recording mode, as of software ver-
sion 4.41, if the battery is removed and rein-
serted within 12 hours, the recording will
continue. (As of firmware version 1.09, restart
time is up to 60 minutes, but for firmware ver-
sions 1.08 and earlier, it is only up to 10 min-
utes.)
When the battery is reinserted during the
allowed time, the LCD returns to the time-of-
day and continues to record the patient’s Holter
signal. When the patient’s recording is ana-
lyzed, the signal recorded while the batteries
were not in place appears as continuous high-
frequency artifact in all channels.
If the battery is left out for more than 12 hours,
recording cannot be restarted. Instead, you will
have to use the recording as is, or you will have
to re-initiate the recording after erasing the
memory on the SD Card.
Note: If the SD Card has been removed and
you wish to restart the recorder without a card
in order to update settings, you will need to
press the following buttons in this exact order
during the 15 second countdown: ENTER,
down arrow, up arrow, EVENT.
