Test Summary

On/Off button allows enabling the test timer. An error message is
displayed and the test timer is not enabled when the provided start
time or stop time is not valid. It is not possible to enable the test timer
while the test is running. When the timer is enabled (On), it is possible
to disable it even when the test is running. This setting is disabled (Off)
by default.
When test timer is enabled, it is possible to manually stop a test case
using the main test case Stop button. However, it is not possible to start
the test case when the Start Time is enabled.
The test timer is automatically disabled either when the user manually
stops the test, or when the given stop time or duration has expired.
Note: When using Visual Guardian Lite for remote control, the timer
configuration values will be based on the PC clock and not on the FTB-8500
Series and FTB-8120NGE/8130NGE. Make sure to consider the time zone
differential if it exists between the PC and the FTB-8500 Series and
FTB-8120NGE/8130NGE.
