When the indicator beads turn pink, the silica gel is saturated and needs to be reactivated. To reactivate the beads, place the entire unit (do not disassemble) in the oven at 325 Fahrenheit for at least 3 hours. Let the unit cool enough to handle, then return to the safe. Note: the indicating beads will gradually turn blue once reactivated.
