keys to
select the required data field and enter data from the keyboard. Thresholds are always entered in the
‘Current’ columns (use ‘ALT’ ‘I’ to enter a negative value). If specific frequencies have been omitted from the

key may be used to skip over these data fields.
Refer to Section 9.5 for details of how to enter patient details and previous data, and then immediately
perform a new test.
