Memory capacity
See Chapter 8 for information about memory capacity. When the amplifier has
approximately an hour of storage left, the green Record button displays a flashing
LED (button X on page 1-5) and an auditory warning sounds.
Clearing the amplifier’s onboard memory
While recording a study, the amplifier records all data collected to its onboard
memory. Data may be erased from this onboard memory only with user intervention.
The data must be erased before starting a new study or to continue an extended study.
If the amplifier’s data has not been cleared after an exam was completed, the
Amplifier Contains Data menu appears when attempting to start a recording. This
prompt shows the size of the exam located on the amplifier, the patient ID under
which it was recorded, and the start/stop time of the recording. There are three options
on this screen, which are detailed below.
Delete Data on Amplifier – This deletes the data on the amplifier and allows you to
start a recording.
Exit and Retrieve Data – This downloads the data to the currently selected Patient.
Choosing this option on a different patient will warn you that the Patient ID’s do not
match.
Cancel – This option cancels the Amplifier Contains Data window. The recorder
will still continue to start, with this amplifier not available. The Amplifier Selection
menu and the Recorder will have to be closed.
