Marking Events
An event can be identified on the DSA or Trend displays by placing an event label
on the display at the point where the event occurs. Up to 52 event labels
(a-z; A-Z) can be placed on the DSA and Trend displays. The event label is stored
and displayed with the DSA and all Trend displays in all four channels.
After touching the MARK EVENT key, touch the YES key to place an event label.
Touch the NO key to cancel marking an event. Touching either key returns you to
the main menu.
The next event label to be placed is displayed above the YES/NO keys on the
message line. The message appears as follows:
MARK EVENT ‘X’
‘X’ is a letter a-z; A-Z. If the event label is ‘Z,’ the message Z is the last event mark
that can be placed is displayed and the Mark Event key will appear dotted after Z
is placed.
Storing DSA/Trend Snapshots
From the Main menu, touch the ARCHIVE key, touch the STORE SNAPSHOT
key then touch the STORE key.
The following messages are displayed on the message line:
SNAPSHOT = UU (ZZ Snapshots Available)
UU is the snapshot number (1 to 44) and ZZ is the number (0 to 44) of snapshots
that can still be stored.
The number of snapshots that can be stored depends on the amount of memory
in the EEG module. The base module can store 11 four-channel or
22 two-channel snapshots. If the module has sufficient memory, then up to 44
snapshots (four-channel) can be stored.
