USER MANUAL
Perform the following procedures for weapon-mounted operation:
1. Verify that the batteries are installed (Paragraph 2.2.2).
2. Attach the weapon mount to the monocular (Paragraph 2.2.10), steps 1 and 2.
3. Mount the monocular, with the adapter, to the M16/M4 receiver rail (Paragraph 2.2.10, steps 3
and 4).
4. Rotate the diopter adjustment for the clearest view of the image intensifier screen.
5. While viewing an object, focus the objective lens (Figure 2-1) until the image becomes sharp and
clear.
2.3.5 IR SOURCE OPERATIONS
WARNING:
The IR source is intended for use in extreme darkness and will be invisible to the naked eye.
However, its light can be detected by other night vision devices.
NOTE:
The built-in IR source is intended for use at close distances (up to 3 meters) when additional
illumination is needed.
1. Pull the power switch knob out and rotate it clockwise to the IR position. With the monocular
held to the eye, confirm that a red light appears in the eyepiece. This indicates that the IR source
is operating.
2. For brief IR operation, turn the power switch clockwise (without pulling) past the ON position.
Confirm that a red light appears in the eyepiece.
2.3.6 OPERATION WITH A COMPASS
WARNING:
The light emitted by the compass can be seen by others using night vision devices.
CAUTION:
If you use the compass on a head/helmet mount with the magnet installed, your compass
readings will be inaccurate. Only the magnet on the metal mount can be removed without causing
damage to the equipment (Paragraph 2.2.12).
NOTE:
• The compass reading is magnetic North, not true North.
• The compass reading is within 2° of correct absolute magnetic bearing. Compass readings
with the mounted monocular (head/helmet mount) can be up to 15° off from the correct,
absolute magnetic bearing. This occurs mostly in the East (90°) to West (270°) direction, and
less in the North (360°) to South (180°). If the compass is inadvertently magnetized, this could
cause an additional 15° error.
• The objective lens focus can be fine-tuned after installation, but in order to obtain an accurate
reading, the compass must be vertical (e.g., the compass image must be level).
