Where can i find a BAIGISH Sakura 10-70X50mm Night Vision Binoculars Scope user guide/manual online?

Dino Direct carries them and has a pretty good description for them but is not complete. If they opearte in the manner I think they do, hold down on the lever to power them- do not pump, just press and hold. Since there is no mention of a battery or cell, this is the usual alternate method to power them.

Otherwise the online information that is most complete is

Binoculars power on, then immediately off NIGHT OWL OPTICS NIGHT VISION BINOCULARS NOXB5

Hello there. Are you pointing your NV binoculars at bright light, if so, please stop. Therefore, if you are not then possibly the iit (image intensifier tube) is bad, or the auto shut-off is also shorted. Night Owl Optics are in El Paso, TX. Call Night Owl up, they won't tell how to fix it. But they will tell where to send it. "It is proporitary" which mean, they are the one to fix it. Sorry, stewbison.

Put new batteries in power does not come on.

Hello, check the battery compartment and see if has been corrupted with leaky battery corrosion.
If it has clean the contact really well. Also, make sure you are using new batteries, and the plority is correct while installing the batteries. A kind of rule of thumb here: if it has a spring, then negative (-) is connected here. Unless it has some else, plugs, etc. stewbison

Does not power up. Put new battery in but nothing happens.

Hello, There could be a number things that go wrong with Famous Trails NV. Little history here.These binoculars, monoculars and some scopes are manufactured in Russia. There could be a malfunctioning switch or switch's, broken wire, faulty controller. Between what can really go wrong with it would be broken wire or image intensifier tube. I think on this model you'll need to remove the front lens, it screw on or off. Once you give it off, there will be ring with three screw.

Remove the screws. Now gently remove the but first remove the eye viewing lens. Be careful here there will be some white wire attached to the switches, IR light, LED will all have wires and the two wire from the battery compartment. Mark the wires and there location on the printed circuit board...all wire location on their boards. Label it very well. Check for broken wires and check the switches. If not broken wires or bad switch then problem would be the green painted tube with a thick black collar around it. To check that you will need 15KV switch DC/AC at 20Khz and about 12ua of current. stewbison

Hello, most of these NV monoculars uses CR123A. It a 3 volt battery about 1/2 size of AA and its girth is a little larger. Aslo, some use two AA batteries. Little information here. Some of these night visison monoculars and binoculars that sealed for water infiltration are epoxy together. stewbison

My night vision scope will not turn on. My LEDs work but you can not see anything in the lens. Yes the cap is off. I tried new batteries. It has very few hours of operating time. Help!

Hello, Welcome to the world of Russian night vision system. That is right, Night Owl Optics Cyclops NOCC3 is manufactured in Russian. The biggest problem with these monocular and binoculars and even scope is that they use cheap 1st generation Russian image tubes and everything else. It would be cost prohibitive to have it fixed, that is, if Night Owl Optics will fix it for you. Hint: Auction it on Ebay as night vision parts. Sorry, GB...stewbison

They do stay on for a while after switch, that is OK. Dim and out of focus may indicate that the output voltage is low. If replacing the battery does not fix it, then the problem may be in the power supply circuit.

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.
