Hi, fello sailors. I have recently been given a pair of Yellow. ITT night mariner 260 Gen 3 night vision binoculars. I don't know how to use them?? the previous owner does not have the manual and can't remeber how to use them either?? So I'm asking the knowlegable bunch out there?? I've worked out that the top single button turns them on but all I get is a red light inside, is this to say the
battery is dead?? there is an oblong middle button for what??? lower down are 2x buttons, one with - the other with + on???? I'm guessing that it's the
battery but I don't realy have a clue?? please help if you can. Thanks.....Paulo........NZ
