Reviewing EEG Data
The module continuously stores the last 2- to 24-hours of DSA and trend data.
The number of hours it can store depends on the amount of memory installed.
You can scroll back and forth in half screen increments using the left and right
REVIEW keys. Data is not displayed until you remove your finger from the left and
right arrow keys. If you keep your finger pressed on one of the arrow keys, you
can rapidly scroll to the approximate place in the data. Time and date information
for the position in the data is displayed on the message line, as well as any event
marks placed in the data.
When reviewed data is being displayed, the message REVIEWED is shown in
reverse video on line two of the numeric zone.
Recalled EEG data (Dual Format Off)
You can store and recall snapshots of DSA and trended data. Recalled data is
displayed in the same format as live data.
When dual format is off, recalled EEG data replaces live data for each channel.
When recalled data is being displayed, the message RECALLED is displayed in
reverse video on line two of the numeric zone.
Recalled EEG Data (Dual Format On)
When dual format is on, two data formats (e.g., DSA and analog) are displayed. If
recalled data is requested, the recalled EEG data is displayed in the second zone.
Recalled data is always displayed below the live data. The message RECALLED
tells you that the data in the second zone is recalled data. This can be used to
display baseline data below the live data.
Live Data
Touch the LIVE DATA key to resume displaying live DSA, analog, or trends. This
key provides an easy means to return to live data after displaying reviewed data
or recalled snapshots.

• When DSA & TRENDS are displayed simultaneously in Dual
Format mode, the Review keys scroll through DSA and trend
data.
