Edit filter
The edit filter function enables the user to specify the particular parameters that are used to display data
records.
In general, the filter function enables the user to retrieve record(s) according to specific search requirements.
The database fields, which facilitate a filter search, are as follows:-
Patient number
Surname
Forename
Position
Department
Company
Test date before
Test date after
The user can select any of the above database fields with the use of the
and
keys and the apply filter
key and then edit the specified filter such that only the record(s) within the internal database which match
the search criteria are identified.
For example
to select all the patient records identified with surname “Smith”, with the filter keys shown on
the database page, use the
and
keys until the required database field (surname) is displayed adjacent
to the test date heading. Press
‘Apply filter’ followed by ‘Edit filter’. The database field and the filter required
parameter should now be displayed at the top of the screen. Enter/amend the parameter within the brackets
so that that the parameter matches the requirement, i.e. SMITH. Press
the ‘OK’ softkey. The records within
the internal database that are identified as Smith would now be listed.
10.4.5
Apply filter
The Apply filter function allows the user to specify which database field is to be used as the filter. To select a
database field use the
and
keys until the required field is displayed adjacent to the test date on the
database display and press the
‘Apply filter’ softkey. The selected filter field will now be displayed at the top
of the display.
10.4.6
Remove filter
This function enables the user to clear the filter and list all records within the internal database.
10.4.7
Import/ Export
This function allows the transfer of test records between the internal database and an external computer via
a USB memory device.
For enhanced security it is possible to encrypt the data. A user-selectable 16-digit password is used for this
encryption, and this same password must be used to decrypt the data on the computer or to import encrypted
data into the audiometer. Thus a note must be made of the user-selectable password which should be stored
securely.
If the user-selectable password is lost then the data will no longer be accessible. But it is, of course,
possible to import or export data without encryption.
Refer to Appendix 1 for more details of software that may be used on a computer to encrypt or decrypt data
files.
The following controls are used for the import/export functions.
