SAFETY SUMMARY
• Read and follow all instructions
• Read all warnings
• Only use the attachments/accessories specified by the manufacturer
• All service must be provided by the manufacturer
WARNING:
This product contains natural rubber latex, which may cause potentially fatal
allergic reactions! If you are allergic to latex, it is important that you strictly
avoid exposure to products that contain it.
WARNING:
Always make sure your firearm is unloaded before you place the scope on the
firearm. Reconfirm that the chamber is empty if you stop the procedure then
resume later. Safe handling rules should be followed at all times.
WARNING:
If a scope is mounted too far to the rear, the eyepiece can injure the shooter’s
brow. Shooting at an uphill angle also increases this hazard because it
shortens the distance between the brow and the rear of the scope. For this
reason, AGM scopes are engineered to provide generous eye relief. Therefore,
when mounting your scope, we recommend positioning it as far forward in the
mounts as possible to take full advantage of this generous eye relief. With hard-
recoiling rifles, serious injury or even death can result from eyepiece impact
with the shooter during the recoil process when discharging the firearm.
Be certain that your installation provides sufficient eye relief for the recoil
generated by your rifle before shooting the firearm.
NOTE: Give special attention to this warning when shooting uphill and/or from
a prone position. These shooting conditions can dramatically reduce eye relief.
PLEASE maintain maximum eye relief when shooting heavy recoiling and/or
magnum firearms. THE USER ASSUMES ALL RESPONSIBILITY AND LIABILITY
FOR HAVING THE AGM SCOPE PROPERLY MOUNTED TO A FIREARM AND
USING THE AGM SCOPE PROPERLY. ALWAYS CHECK THE CONDITION OF
YOUR MOUNTING SYSTEM PRIOR TO USING YOUR FIREARM.
WARNING:
The proper usage of the device is important for safe operation!
Therefore carefully read this manual!
WARNING:
If the device was left in storage for a longer period of time, before use, check
its functionality.
WARNING:
Disassembling of the device is prohibited, except in authorized repair centers.
WARNING:
Please remove the batteries from the battery compartment before connecting
the device to your PC, or it may cause computer damage.

AGM Global Vision6
WARNING:
The external optical surfaces should be clean at all times. Touching the optical
surfaces with bare hands is not recommended.
WARNING:
Sand and sea water can damage the optical coatings!
WARNING:
Do not point the device directly at the sun!
WARNING:
Image performance is dependent on scenery and atmosphere conditions.
Contrast in the same image may vary as a function of the time of day due to the
effect of the sun. For example, at sunset objects will have absorbed different
levels of heat resulting in greater temperature differences and better contrast.
WARNING:
When left in storage for a longer period of time, batteries have to be
removed and stored in polyethylene bags to prevent contact with metal.
(It is recommended to recharge the batteries every two to three months.)
WARNING:
When carrying or transporting the device, put the protective lens cap on!
WARNING:
Condensation can cause fogging of the optical surfaces! Condensation occurs
when the temperature or humidity changes as follows:
– When moving the device from cold to warm place or vice versa;
– In places with high humidity.
When equalizing the temperature of the device with the environmental, the
condensation disappears. Use the towel to remove moisture.
NOTES:
• The detector spectral band provides better visibility through smoke, dust,
rain, smog, etc.
• Infrared radiation does not travel through glass. As a result, the clip-on does
not detect objects if they are behind glass windows or other barriers.
WARNING:
Clean the lens surfaces with the lens tissue or a dry cloth!
LEGAL NOTICE
Before attaching to weapons, check the regional legal regulations in the area
of application. The attachment to a weapon is always the sole responsibility
of the user.
