5.3.6.2 Log Retrieval
All previous therapeutic delivery logs can be retrieved and saved
onto a USB Key or deleted from internal memory. The interface
consists of a series of chronological sub-folders from which the
user is allowed to double-tap on the touch screen to descend
through the hierarchy. The standard naming sequence is Year,
Month, Day, followed by special folders with the time of day.
These time folder icons show a hand underneath, meaning they
contain all files generated from a single vaccine delivery. The “ ”
folders allow the user to return to the previous level of hierarchy.
Special time folders display basic information on the right hand
side of the screen when selected. Identification numbers, time
of day, and status completion indicators help the user find the
correct vaccine delivery run to download.
When selected by a single tap on the touch screen icon, any
level of hierarchy can be saved to a USB Key inserted in the front
panel by pressing the SAVE button. The hierarchy structure will
be maintained and copied to the USB Key. The DELETE button
is also available to remove the hierarchy from internal memory.
This delete is permanent and the lost files cannot be recovered.
A maximum of 20,000 delivery logs can be stored on the internal
system memory.
DEPENDING ON THE NUMBER OF FILES TO BE DELETED, THIS
PROCESS CAN BE SLOW.
