Problems with JL Audio fathom Subwoofer

I just purchased 2 used Fathom F113's to run in my 2 channel system. I am having a problem on one of them. When I power it down or it goes to standby the ARO settings are getting erased? Is there a battery that could be dead in it that holds the memory settings? Having to leave it on all the time to keep the setting! 
In all seriousness, why wouldn’t you contact JL directly? Much faster answer that way.
