This is a common problem with this mode. If you are sure regarding the battery, then try to reset the rangefinder.You need to push the mode button and power button simultaneously for 30 seconds. This would reset the device.

If problem still persists, revert and we would follow up from there.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

    Thanks for your response!!

    Do you see any error message on the screen?
    Did you play with the settings? ( default settings )

    If you didn't play with the settings, no error message, battery is new - More often it is either a programming problem or an alignment is needed.You need to contact the manufacturer for the same.Unfortunately, this is not a DIY.

    The number is: 1-800-645-6678
    Telephone Support is Available 8am EST to 2am EST 7 days a week.

    I am sorry for the bad news.Your need to send your unit for repair.

    Let me know,if needed further assistance.

As far as I know, you point it at something a distance away and press the power button. They're a very simple device but will likely not work indoors or over very short ranges.

If you're still having problems with it, it should still be under warranty, I would return it to the store immediately. If you have any issues with the store staff, do not leave the device with them and contact Nikon directly for help with warranty. You should never have issues with a product out of the box.

Nikon 440 pro staff range finder wont read distance

I just got mine to work. It was doing the same thing. I guess I re-set it. I figured there had to be some way to re-set it. So I pushed the mode button and the power button simultaneously for 30 second. Then it worked! Wooptidoo :)

there is a silver quarter sized screw out cover on the battery compartment.  It has a slot so you can use a coin or screwdriver to remove the cover.
