Hi,
As per this thread:
viewtopic.php?f=4&t=4403&p=12866&sid=88 ... c73#p12866
I'm having trouble with battery life on one of my HR92s.

I notice there is a mini-USB socket tucked under a small snap in cap. Presumably this is for manufacturing programming. Has anyone tried attaching to it for debuging?

AFAIK the port is only used for the window open contact.

I didn't know you could do that! Looks like it's Honeywell parts HCS30 & ACS90.
Thanks for your time.
