Caring for your REX PRO
This chapter is designed to help ensure you and your REX PRO have
a long and happy life together.
Installing new
batteries
The REX PRO card is powered by two CR2025, 3-volt batteries,
which can last for up to six months of average use.
To remove the old batteries and install new batteries:
1
Turn over the REX PRO card.
2
Insert the tip of a paper clip into the small hole on one of the
battery compartment doors.
3
Gently press the battery compartment door towards its hinge and
then push outward to open the door.
4
You may need to tilt the REX PRO card so that the battery slides
out.
5
Insert a new battery, with the positive (+) side facing the front of
the REX PRO card.
NOTE
If you see a message, “Battery is low,” it is important to
replace the batteries promptly; if they lose all power, all the
information in your REX card may be lost.
