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).
1. To activate the IR illuminator, turn the monocular on. Pull the IR illuminator out and flip the turn-pull
function switch (A) CW from ON to the IR position. A red light will appear in the eyepiece to indicate
that the IR illuminator is operating.
2. Focus the IR light, if necessary, by placing the pivotal focusing lens onto the IR illuminator output
window (C).

3.3.3 OPERATING UNDER CHANGING LIGHT CONDITIONS
If the ambient light level exceeds the limit of 100-300 lx for more than 10 s, the NYX-14 automatic pro-
tective system will shut off the intensifier tube. If a mission must be carried out in changing light condi-
tions, the user can shut down the protective system manually by closing the photoreceiver.
