Battery Insertion
The Smart® IsoDry® Nitro-Watch™ uses a CR2032 coin cell battery to keep time while power to the system is off. The
battery needs to be added to the circuit board before system start up. If no battery is present the system will not keep
time when the system is powered off and the system time will need to be set again when the system is turned on.
Follow the steps below to install the battery:
1.
Unfasten the screws on both sides of the Nitro-Watch™ Controller to remove the cover.
2.
Remove the cover to expose the circuit board.
3.
Insert the battery into the battery holder.
4.
Reattach and secure the cover over the circuit board.
5.
Begin System Configuration process.
