INSTALLING THE FOB BATTERY
The fob uses a commercially available CR2032 coin cell battery.
The battery will normally have to be replaced every 3 to 6
months depending upon how much the fob is used.
The fob case can be pried open using a small flat blade screw-
driver, then snapped back together starting at the battery end
and working back toward the opposite end.
After the battery is replaced, the system does a quick
check by illuminating all the LED indicators. If all of the
LEDs do not illuminate, then either the battery or the
LEDs are not working.
