9 Time and Date (not available on XR 2000)
The XR remote display has a precision time clock that compensates for variable

power for this clock.

9.2 Battery / Battery Replacement
The XR displays use a 3 Volt lithium battery. Power is drawn from the battery only when
the unit is disconnected from AC power. If time and date are lost when the unit is
disconnected from AC power, the battery likely needs replacement.
1. Remove the old battery from the J22 terminal on the Controller board by hand.
2. Observe proper battery polarity before inserting new battery.
3. Ensure the battery is seated correctly in the J22 terminal.
CAUTION! Risk of explosion if battery is replaced by an incorrect type. Dispose
of used batteries according to their instructions.
CAUTION! Never use metal objects such as screwdrivers to remove batteries!
This may result in personal injury or damage to the unit.
