LN-EIR850 &
LN-EIR940:
EXTENDED RANGE LED
INFRARED ILLUMINATORS
Thank you for purchasing a quality LUNA product. The model LN-EIR is a very popular
accessory to any standard or digital night vision unit. It provides a much longer effective
viewing distance than the usual stock built-in IR illuminator.
Please refer to the images below to identify the parts of the illuminator:
GLOSSARY:
1 – Beam width adjustment
2 – Mounting Bracket
(LN-EIR850-3 / LN-EIR940-3 shown above
)
3 – Horizontal and Vertical beam adjustments
4 – Battery Compartment Cover
5 – ON/OFF Switch with Variable Power Rheostat
LN-EIR850-2 / LN-EIR940-2
BATTERY INSTALLATION:
To install the battery please unscrew the battery compartment cover (4) by rotating it
counterclockwise. It may be necessary to hold the rubber attachment string with one finger while
unscrewing the battery compartment cover to ease the process. Once the battery compartment is
opened, please insert one 3V Lithium battery, CR123 type as shown on the body of the illuminator
according to (+) and (-) polarity. Replace the battery compartment cover. The IR is now ready for
use. IMPORTANT: USE OF RECHARGEABLE BATTERIES IS PROHIBITED AND WILL VOID ANY
WARRANTY CLAIMS
TURNING THE UNIT ON/OFF:
To turn the illuminator on please rotate the ON/OFF switch (5) clockwise. You will hear a faint clicking
sound indicating the IR is ON. The illuminator has a smooth power adjustment and the further you
rotate the switch clockwise the brighter the beam will become.
IMPORTANT: once you reach the maximum power the rotation will stop. NEVER try to over-rotate
and never apply any force once the ON/OFF switch is at the maximum power level. Trying to force
switch to rotate further at that point may damage it and will void any warranty claims.
To turn the illuminator off, rotate the ON/OFF switch counterclockwise until stop. You will hear again a
faint clicking sound indicating the IR is OFF.
NOTE: if you turn on the IR and its flashing, it means you need to replace the battery.
