3.3 OPERATING PROCEDURES
3.3.1 OPERATING PROCEDURES
These procedures should be performed under nighttime conditions only.
CAUTION:
Use of the Spark brightly lit conditions may damage the unit’s intensifier tube.
1. Verify that the battery is installed as indicated on the monocular body.
2. Make a visual estimation of the illumination level in the viewing area. The required level of
illumination is less than 1 lx (late twilight sky conditions).
3. Remove the lens cap and place it over the housing of the lens.
4. Turn the function switch ON. The green indicator light (Fig. 3-9, D) indicates that the unit is ready for
operation. After a slight delay, a green glow will appear in the eyepiece of the monocular.
5. Adjust the unit diopter by rotating the ring of the eyepiece.
6. Observe the scene. Rotate the focus ring until the image is clear and sharp.
CAUTION:
Bright sources such as firelight, headlights, searchlights, etc. can damage the Spark. Avoid exposing
the unit to these types of light sources.
3.3.2 IR ILLUMINATOR OPERATIONS
CAUTION:
When operating the device in extremely dark conditions, the light from the unit’s IR illuminator will
be invisible to the unaided eye. However, the light can be detected by other NVDs.
NOTE:
The IR illuminator is designed to provide additional illumination (when needed) while viewing scenes
or targets from a short distance (up to 3m).
