Automatic Brightness Control System
The unit is fitted with an Automatic Brightness Control System. The Automatic Brightness Control Sys-
tem maintains the IIT screen’s brightness level, even when faced with inconsistent light conditions.
Bright light cut-off system
The Discovery bi-ocular is designed to operate under only limited amounts of bright light when the
front lens cap is removed. A Bright light cut-off system protects the image intensifier tube (IIT) from
damage, and prevents the reduction of photocathode sensitivity when the device is turned on in ex-
cessively lit environments.
The protective system uses a light sensor to analyze the illuminance level of the surrounding environ-
ment. In the event that the maximum light level is exceeded for more than 10 seconds, the image
intensifier will automatically shut off. As soon as the illuminance drops to an acceptable level, the IIT
will turn back on.
NOTE:
Do not point the bi-ocular at bright light sources. Neither the Bright Light Cut-off System nor
the Automatic Brightness Control System will protect the IIT photocathode from damage if the
unit is exposed to bright light sources, such as fire, car headlights, lanterns, etc.
Automatic Shut-off System
The Automatic Shut-off System will automatically turn off the bi-ocular when it goes unused (the con-
trols remain untouched) for more than 60 minutes.
Low Battery Indicator
A red light will flash in the field of view to alert you that the Discovery’s battery needs to be replaced.
STANDARD COMPONENTS AND OPTIONAL EqUIPMENT
1) Armasight Discovery Bi-ocular
Night vision bi-ocular with 3x, 5x or 8x magnification.
2) Objective Lens Cap
The objective lens cap is designed to protect the objective lens from physical damage, as well as allow
for the testing of the device’s operation in daylight.
3) Eye Cups
The rubber eye cups are designed to protect the eyepieces and to provide comfort of use for the user.
4) Light Sensor Cap
Putting the cap on the light sensor disables the sensor and gives the use the option of operating or
testing the unit under brighter light conditions. As a protective measure, normal positioning should
leave the sensor exposed and operational.
