This section contains the information required to plan the physical placement of the HSD-440 
terminals. 

The Outline and Installation diagrams, shown in Figure 3-7 and Figure 3-8, illustrate the 
physical and mechanical specifications of the HSD-440 terminal.

In typical aircraft installations, the HSD-440 terminal assembly fits into standard ARINC, 
8-MCU mounting trays. Specialized trays that meet the requirements for installations of the 
HSD-440 terminals on Helicopters are also available from EMS SATCOM. 

All HSD-440 terminal ARINC installation trays are included in the Installation Kits. Table 3-1 
describes the HSD-440 terminal Installation Kits available from EMS SATCOM.

When selecting a location for the HSD-440 terminal, allow for adequate spacing for the 
installation while providing reasonable access for servicing. Leave a minimum gap of 0.5 
inches between LRUs.

The SCM holds SIM cards that contain data for the operation of SBB services.

To remove the SCM:

 1. Remove the two screws from the front panel of the HSD-440 terminal.

 2. Remove the SCM from the HSD-440 terminal, as shown in Figure 3-1.

To install the SCM:

 1. Insert the SCM into the slot on the front panel of the HSD-440 terminal.

 2. Tighten the two screws on the SCM.
