This publication provides maintenance and operating instructions for the
MS-2000(M) Distress Marker Light.
1. Purpose
The light is designed and intended to provide aircrew and other
personnel with a high-intensity visual distress marker signal for use in
the event of unscheduled abandonment of aircraft in isolated regions
and other emergency and/or special operational mission situations.
2. General Characteristics
. The MS-2000(M) Distress Marker Light is a lightweight, compact,
battery operated, portable unit that is designed to be used as a multifunctional light during emergency and/or clandestine special mission
situations. The light is designed to attract attention, to assist in location
and to facilitate personnel rescue operations in both overt and covert
operations.
. The light system consists of a main body case containing the
electronics, lamp, batteries and the flashguard (FG) shield containing
one infrared (IR) and one blue filter. The flashguard also has raised
battery polarity indicators to assist in non-visual battery replacement.
The case is fabricated of high impact, cut resistant thermoplastic
material and designed to insure watertight integrity of the main body
case. The light utilizes a xenon strobe lamp, is powered by two AA
batteries and is actuated by a magnetic reed switch. The light is
designed for one-handed operation and may be operated by either hand
or attached to any object.
. The flashguard shield contains both an IR and blue filter which are used
as safeguards in hostile territories so as to prevent possible signaling
confusion (i.e., small arms ground fire) between the signaler and
observer. The IR filter provides omni-directional transmission of IR
wavelengths. The blue filter is used for line-of-sight (directional) light
transmissions. The IR filter is designed for use during clandestine
operations.
. Electrical power for the MS-2000(M) is provided by two 1.5V, AA,
alkaline batteries located in the base of the main body case. A retained
battery door is provided with an "O" ring seal to insure its watertight
integrity. Additionally, electrical power is controlled by a magnetic reed
switch located on the side of the main body case. This switch also
insures waterproof integrity of the main body case.
