My TAP Controller is forgetting the date and time between reboots. Is there a battery on the controller board that needs to be replaced?

Your controller forgetting time and date between reboots is indication that you need to replace your clock battery.

Yes, there is a coin cell battery on the back of the controller circuit board. The controller will accept either CR1220 or CR1225. You can also purchase a replacement TAP Clock Battery on our online store.
