Regular Arlo cameral (not Pro)

I have synced 4 of the 5 cameras that I purchased, however the 5th camera will not sync.  The blue led just blinks slowly and never gives either the fast blink to show that it is synced with the base station and it never blinks amber, either.

Have you tried opening and closing the battery door? If it's a hardware problem, you can either swap at the store or open a case with support here.
