Reviewing Alarms

The SAM 935 can store over 250 alarm events. Each stored alarm consists of a spectrum and all of the
information necessary to analyze the spectrum. Stored alarms can be viewed by using the

and

arrow

keys:

Review stored alarms by pressing the

or

arrow keys from the main Surveillance monitoring screen:

• From the main display, press the

(left) arrow key to display the previous (most recent) alarm.

• From the main display, press the

(right) arrow key to display the first stored (oldest) alarm.

Once you are in review mode, the

and

arrow keys move from alarm to alarm in a circular fashion as

shown in this example below:

• At any time in the review process, pressing the R

ETURN

(F2) key will bring you back to the main

monitoring screen.

• Press P

RN

S

EL

(F3) to print the selected stored alarm through the serial port. An example of this

printout is shown on page 59, Section 7.1.

• Press MCA (F4) to enter the Manual mode of operation; see Section 5.4 for more information.

A Memory Full message will appear on screen if the stored alarms approach the memory capacity. When
memory is full, the earliest alarms will be discarded to make room for the most recent alarms being stored.
If you see the Memory Full message, you can download the stored alarms to a remote computer, if
desired, and then

Clear Stored Alarms in the Utilities menu.
