The Sentinel GS night vision riflescope is intended for observation and
shooting at dusk or during nighttime hours. It is a passive starlight device, and
in most conditions does not require an artificial or IR light source. The
Sentinel GS is a universal night vision scope, which is ideal for night
observation and hunting.
USING THE RIFLESCOPE
The Sentinel GS was designed to provide many years of reliable service. To
ensure longevity and performance, it is necessary to follow all procedures
and guidelines outlined in this manual.
Warning:
The Sentinel GS is not recommended for use with cartridges producing recoil
rating higher than 3700 joules or calibers in excess of 7.62/.308. Manufacturer's
warranty will be voided if damage is caused by caliber cartridges greater than
7.62/.308, hand made cartridges or shooting from a smooth-bore barrel.
Do not remove the lens cap in a lit area if the scope has been activated or if
the eyepiece is emitting a green glow.
The riflescope features bright light protection system which prevents
the screen of the tube from burn-through in case of rapid change of
illumination level. If a bright object (such as flashlight, headlights, lamp
etc.) appears in the field of view or if the unit is switched on without the caps
on the lenses, the riflescope switches off, the image grows darker. After the
unit returns to its normal mode, green and uniform image will be restored.
Normal operation restores automatically within a second unless the unit
was switched off manually.
Do not remove the objective lens cover in a lit area immediately after
using the scope. It will stay activated for 20 minutes after the unit has been
turned off.
The scope has an IPX4 water resistance rating. It is water resistant and
can be used in inclement weather conditions.
Do not attempt to repair or disassemble the scope!
Clean the scope's optical surfaces only if necessary, and use caution.
Remove dust and sand by blowing air across the optic surface, then apply
lens cleaning fluid for multi layered optics onto a soft cloth or tissue and
wipe carefully. Do not pour any fluid, including alcohol, onto the lenses
directly.
The scope can be used in temperatures ranging from -30 С to +40 С.
However, when it is brought indoors from cold temperatures, wait 3-4
hours before using the unit.
Consult a qualified gunsmith if there is difficulty attaching the scope firmly
to a rifle or if there is uncertainty about the right type of mount. The
weapon mount can be deformed or destroyed by shooting with a
riflescope that is not mounted correctly.
Regular maintenance of the scope will help keep the device free from
malfunctions and untimely wearing of parts and connectors.
Failure to observe these warnings will void the manufacturer's warranty.
