BATTERY INSTALLATION AND REPLACEMENT
The sensor is powered from a single CR2450 Lithium / Manganese Dioxide (Li/MnO2) baery.
Under normal operaon, the internal baery should last for between 1.5 to 2 years using the default
reporng interval of 5 minutes.
If a sensor fails to broadcast, one of the LEDs no longer lights when pressing the push buon, or the
sensor appears to connually reset, the baery should be replaced.

CR2450 baeries from other manufacturers may be used, however it should be noted that their
capacity may be lower and/or the internal impedance of the baery may be higher, both of which will
result in a reduced runme of the baery compared to those in the above table.
