When the Inactive Pair, Active Pair or specific 
Wideband service is selected, the Threshold Limits 
screen will be displayed. This screen displays a list 
of measurements performed in the selected Autotest 
and the corresponding pass/fail limits for each 
measurement. 
The limits indicate the values at which the 
measurement result passes (OK), is marginal (Yield 
Sign) or is unacceptable (Stop Sign). The lower limit 
threshold value is shown in the box on the left, the 
upper limit in the box on the right. 
If the test result value passes or is unacceptable, the 
pass/fail result will correspond to the symbol under 
the box (either Stop or OK). If the test result value is 
between the upper or lower limit, the pass/fail result 
will be marginal (Yield Sign).
Use the [Up] and [Down] keys to highlight the 
desired test. Use the [Tab] key to move the cursor 
to the limit value and enter the new value using the 
blue keys. Press the [Setup] key to restore the factory 
default values for the selected test. Press the [Enter] 
key to accept the changes or the [Return] key to 
ignore all changes and return to the Threshold Setup 
screen. If invalid limits are entered, a warning screen 
will be displayed. Press the [Enter] key to return to 
Edit Limits screen and make appropriate changes to 
the limits.
