Safety Summary
Before operating this product, carefully read and study this Operation and Maintenance Manual.
The COT NM-108 BC night vision module is a precision electro-optical instrument and requires
careful handling. To avoid physical danger or equipment damage when using the COT NM-108 BC,
follow all WARNINGS, CAUTIONS and NOTES.
Below you will find definitions of the alerts that appear throughout this Manual:
WARNING — Identifies a clear danger to the person operating the equipment.
CAUTION — Identifies risk of damage to the equipment.
NOTE — Serves to highlight essential procedures, conditions, statements, or conveys important
instructional data to the user.
WARNINGS:
• When installing the equipment on a weapon, be sure the weapon is clear and the safety is on
before proceeding.
• It is recommended that you use an eyecup on the eyepiece of the day scope, allowing for the
eyepiece diameter and eye relief and having side paddle preferably in order to escape detection.
• The light from the infrared illuminator is invisible to the unaided eye. However, the light can be
detected by other night vision devices.
CAUTIONS:
• DO NOT dismantle the equipment.
• Keep the equipment clean. Protect it from moisture, dramatic temperature changes, and electric
shocks.
 DO NOT drop or hit the equipment.
• Protect the equipment from overexposure to light: DO NOT activate the equipment in daylight
with the objective lens cap removed; DO NOT aim the equipment at bright light sources (a fire,
car headlights, lanterns, street lamps, room lights, etc.).
• DO NOT force the equipment controls past their stopping points.
• DO NOT leave the equipment activated during breaks in operation.
• Verify that the equipment is off before installing a battery.
• DO NOT store the equipment with the battery still in it.
• To avoid deformation or damage, remove the light suppressor from the COT NM-108 BC
before placing the equipment in storage.
• Thoroughly clean and dry each item before placing them into the storage case.
NOTES:
• Optical axes of the COT NM-108 BC and day scope should align. It is not recommended for the
distance between the axes to exceed 3 mm. If the difference in the axis heights of the COT NM-
108 BC and day scope above the weapon rail exceeds 3 mm, you will need to replace the day
scope mounting rings or monoblock.
• At operating temperatures below -20 °C, alkaline battery life will be severely reduced. Under
said conditions, the use of lithium battery is recommended.
• The equipment requires some level of ambient light (moonlight, starlight, etc.) to function
correctly.
