Hello, it could a bad switch. Have you tryed hold down on the switch and see that works. If so, then the switch is faulty. You know that this NewCon Optik CON STARGATE-M is Russian manufactured by Optik one of the six or seven Russian companies manufacturing these NV devises. GB...stewbison
It could be on the top with a small hatch door that holds two AA batteries. Also, there could be a screw in cap on the back that could hold one or two CR123A 3 volt batties.
Unless it has finger crip lever on the top, this piezo electric plunger. The plunger needs to be activated about twenty plus times to build some current for the storage capacitors that will charge a small batteries. stewbison
Yes, First, when you take the lens off you binocular make sure you are in a very clean room. All you have to do is unscrew them. Use a good lens clean that is anti-static. If you don't every piece of lent, dusty bugs, flaky shin, etc. will be attached to those lens. stewbison
Hello there, alway check the battery. It can be check with a DMM for voltage but the battery needs to have a load on it. Hook up a couple flashlight bulbs across the + and - terminals. Then check the voltage across the battery with the load (bulbs). If the voltage across the battery is about 2.6v on a 3 volt battery with the load it's OK. Example: The same with your car battery that has a 12 volt system.---put a DMM across the terminals and it show approx 12 volts. Try starting the vehicle and if the voltage dropes below 10 volt while trying to start the auto, then the battery is or needs to charge. or it's bad Example, to check you vehicle to see on DMM if it is really charging. Start the vehicle and let it run, then check the voltage across the 12 volt battery. It should be 13.8 volts. This will indicate that the charging system of the vehicle is work. stewbison
Yes, some time the IR
illuminate is encased in a small tube. Just unscrew the cover on the IR and see
if you can remove it from the. Also sometime IR illuminator is in the back with
a couple screws holding it in place. I will also tell it could get to be
complicated. Just take you time and you will succeed in your endeavors.
It's not a problem with your NV monocular. These spots will occur on any image
intensifier tube. EXAMPLE: Military standard states that if more than one black
spot appears on the tube, then this image tube is rejected for use by the US
Military Now like you NewCon Optik DN 140M it manufactured in Russia and they
quality control doesn't even match the US Military Standards. On scale 1 to 10;
US Military rating for the image tube would be 10+ while the Russian maybe 2+
and I said maybe. Another thing to remember here is that no two image
intensifier tubes are the same. It just like finger prints on people not two are
the same. It normally. stewbison
there should be a beveled lock ring on the eyepiece.look at it closely...there should be numbers or letters on it...now turn the eyepiece in half way....hold the eyepiece with one hand and wrap a piece of rubber cord around the the bottom of the eyepiece that has the numers or letters on it and twist ,,,it should come apart...the eyepice is actually two pieces the problem is sometimes you will have to apply a little heat to break the seal do not use pliers or it will damage them ..if i can talk you through it i will.. give me a call at 5088330650......www.reichinstruments.com
Check the HV to the tube and see if you can see any discolouration or spots on the tube - they often indicate tube failure. Many binoculars use the one power supply for both tubes as the current demand is very low. Often, one tube operation indicates tube failure, but a wire or connection could be at fault.
