Auto shut OFF at bright light
Each unit has a built-in high light sensor located near the IR illuminator (2, Fig. 1). This sensor shuts the monocular off after about 45 seconds of exposure to light exceeding 10-1lux.
To reset the monocular switch it off and then back on as described in 6.3 and 6.2.
High-light shut-off feature does not mean that the Unit will react to occasional flashes or bright spots. It protects the tube against excessive light exposure only in order to avoid permanent damage.
Auto-gating system
The NVS 14-3AG and NVS 14-3AGBW variants contain, in addition to the systems described above, an auto-gated power supply. This system automatically controls the power supplied to the IIT in changing lighting conditions. This serves not only to protect the IIT from exposure to bright lighting sources, but also to automatically provide the user with the optimal image regardless of prevailing light condition.
