3.1.9 MOUNTING THE SPARK TO A STANDARD US MIL HELMET/ HEADGEAR
ASSEMBLY
To mount the Spark to a Standard US Mil helmet or headgear assembly, use an optional transfer adapt-
er. Perform the following steps:
1. Push down on the lever (C). Mount the adapter (A) to the Spark rail (B).
2. Align the adapter prism (D) with the helmet/ headgear assembly mount (E). Slide the Spark back-
wards until its alignment boss is in line with the alignment groove on the helmet/ headgear assembly
mount. Push down until the Spark locks into the helmet/ headgear assembly mount.
To dismount the Spark from the helmet/ headgear assembly, push down on the lever (F) and remove
the unit.
Push down on the lever (C) and remove the adapter from the Spark rail.
The transfer adapter can be adjusted for either the right or left eye. In Figure 3-9, the Spark is shown in
the proper position for the left eye. Readjust the adapter for the right eye as follows:
1. Push down on the lever (C). Remove the adapter from the Spark rail.
2. Loosen the nut (G), and turn the adapter around between the two fixing devices. Retighten the nut
(G).
3. Mount the adapter to the other Spark rail located on the opposite side of the unit.
