Programming methods and events 3-35
can replace the current method with one of the methods previously stored.
When you retrieve a previously stored method, you replace the existing
method conditions with those of the stored method.
The method number displayed on the Home screen is that of the retrieved
method until you make a change. Any parameter change alters the current
conditions so that the original recalled method is no longer in effect, causing
the method number to change to an asterisk.
The operating parameters at the time of system shutdown are restored on
startup. However, any timed events or thresholds associated with the method
are deactivated when power is restored. On startup, you always see an
asterisk inside the method icon on the Home screen.
When the detector is operating under remote control, the remote icon appears.
Programming timed events
You can program up to 50 timed events, to the nearest 0.01 minute. As you
enter timed events, each new event appends to the end of the timed event list.
You can enter a time that is not in sequence with the events entered
previously, and the timed event list is sorted when you press Next. The
detector allows programming of the timed events listed in the following table.
