Module positions
Module positions are numbered 1 to 24 as shown below:
The Indigo 4 frame showing slot numbers (and left hand retaining brackets removed)
Before fitting or removing signal modules, one or more retaining brackets may need to be
removed. Retaining brackets prevent the modules from being inadvertently removed or
from coming out during transit. They may also prove useful in OB vehicles when
travelling over rough ground.
Inserting modules
To insert a module proceed as follows:
Remove the two screws holding the bracket adjacent to the slot intended for the
module and keep both the screws and bracket in a safe place
Insert the module into the appropriate guides and push it fully home
Refit the retaining brackets if required

Removing modules
To remove signal modules simply pull on the handle and withdraw them from the frame,
with the retaining brackets removed.
All Crystal Vision cards can be inserted and removed whilst the frame is powered without
damage.
