1.5 Different Models
The three Argus models may require different steps to replace similar boards or components. A separate
description is given for each model when necessary.
Models 3000 and 5000 look the same from the outside. Inside they are very similar, but the 5000 has
an additional board for its database. (The 3000's database is located in a set of ROM chips on the CPU
board.) The 5000 needs more circuitry because of its ability to interface with other equipment. This
takes up room on the CPU board. The 5000's database is also larger, and more chips are required to
store the database.
The 7000 can almost be thought of as a 5000 turned on its side. The top and bottom panels of the 7000
are similar to the right and left panels of the 5000. One major difference in the design of the two units
is the positioning of the database board. The 7000's database board is exchanged from the front of the
unit, and can be replaced without removing the 7000 from the aircraft. To remove the database board
in the 5000, you must first remove the unit from the aircraft and then remove the right side panel to get
to the board. Another difference is the transfer board in the 7000, which interfaces the database board
to the CPU board.
Both the 5000 and 7000 contain a lithium battery, which energizes the internal clock when the unit is off.
The 3000 does not have this battery, since it does not display time.
