Battery Replacement and Cross Reference

Battery Cross Reference

If your Ovu-tec fails to light, it is most likely that the batteries need cleaning.
(The normal life-span of the batteries is 2-3 years.)

1. To replace the batteries: Remove lid. (you should see that the top of your unit is black, and lower half is white.)

2. Carefully pull the bottom white casing (where the illuminator button is located) sometimes it’s easier to pull it with a slight twist. (now you should be holding the black unit). On the top you should see the eyepiece of the unit on the bottom you should see two copper tabs with a ‘+’ sign, this is where the batteries go. -Be careful not to lose the cap.

3. To access the batteries. hold the unit with lens facing down, you should be looking at the ‘+’. If you turn that lid counter clockwise you can now remove it and the batteries with a cloth an reinsert them. If this does not work, take the batteries to a Watch Repair Shop they should be able to test then and give you correct replacement size. Batteries are not warrantied.
