Digitize, Inc. 700248-0002 Rev. C 02/16
Specification Subject to Change Without Notice
1-4
The four lines of large text is the first page of the user text information for the last condition.
The condition flashes along the left side of the three lines when it is received. After
ACKnowledgement, the condition stops flashing and remains illuminated. Additional pages
of user text appear in smaller type below the four lines of large text.
*The user can select the order in which the text information is displayed to the Dispatcher by
using the SET 39 menu.
Below the double yellow line is space for a list of the current open conditions. The number
of conditions that appear here is dictated by the number of conditions received and the
amount of lines that appear above the double yellow line. For instance, if there are quite a
few pages of user text messages listed above the double yellow line, fewer open conditions
may be displayed below the double yellow line. When three or more text pages are present,
they may be accessed by depressing the SNGL/MULTI PAGE DISP soft key.
The last part of the display provides the titles to the programmable keys on each particular
System. Their availability is determined by the options installed in each unit.
1.7 MEMORY
Each SYSTEM 3505 is supplied with 150 screens of nonvolatile, nonmagnetic, field
programmable memory for storage of user text information. This memory is located in the
“System” memory module and occupies the first IC socket, (U1) of the first memory
motherboard, which is provided with the System. All memory module data will be
maintained in the event of a complete power failure, including the loss of battery backup.
There are seven empty memory sockets available on the System supplied memory
motherboard. Nonvolatile, nonmagnetic storage may be added to the SYSTEM 3505 by
installing memory modules and additional motherboards. Please refer to Figure
