REPLACING THE BATTERY
The Frame Controller is fitted with a 3V Lithium battery type CR2032. This battery is used to power non-
volatile memory of some of the frame controller's parameters while power is removed from the frame.
Before attempting to change the battery remove power from the 7800FC card.
