3.
Flip the battery cover open and reveal the two batteries.
4.
Remove the two CR123A batteries with a screwdriver (or a finger) and dispose of them properly.
Note
: Do not remove old batteries from a lockbox until you have a replacement in hand.
Also, do not carry unpackaged batteries in your pocket or purse as metal objects could
cause a short circuit and thereby cause bodily harm or property damage.
5.
Using two, new CR123A batteries, install each battery into their battery cavity with the positive
terminal going in first. The terminals are staggered, so the batteries will be facing different
directions. Refer to the battery cover for proper battery terminal positions.
6.
After putting the new batteries into the lockbox, install the battery cover. There are tabs on the
bottom of the cover that slide under the hooks directly above and behind the battery cavities.
Slide the tabs in under these hooks at an angle and lower the front of the cover down flat.
7.
Re-install the two battery cover screws with the Phillips head screwdriver.
8.
After you replace the batteries, contact Technical Support at 1-877-736-8745, so we can
document you have changed the battery in the
NXT/NXT Wireless
lockbox and make sure it is
working properly before you use the lockbox.
