Mechanical Layout and Interfaces
The reference code of the Extension Cards includes a letter that defines their compatibility
either with “A” slots, “B” slots or both:
•
FL
A
xxxx - designates cards that fit into “A” slots
•
FL
B
xxxx - designates cards that fit into “B” slots
•
FL
X
xxxx - designates cards that fit into both “A” and “B” slots
In addition to the card reference, each type of extension card bears a visual compatibility
symbol on its front panel. The visual symbols are shown in the table below:
●●○○
2 first slots only (A)
●●●●
In any slot (X)
○○●●
2 last slots only (B)
4.5.2. SIM-Card Insertion
A SIM-card obtained from a wireless phone provider is necessary to communicate through
the 3G GSM Extension Card. It should be inserted before inserting the Extension Card in the
Base Unit because there is no external access to the SIM-card holder.
The SIM-card holder is located at the components side of the Extension Card. Carefully slide
the SIM-card in the holder as shown in the picture below. Make sure the card is fully inserted
against its arrest, otherwise it could damage both the drawer and the SIM-card when the
Extension Card will be inserted in the Base Unit. Note the position of the cutoff (1) of the SIM-
card.
