I've searched for information about the normal operation of the Ice Tube clock but I can't find it anywhere, so I'm asking here.
What is expected to happen if I unplug the power adapter for a short while and then restore power? I'm not sure if my clock is working right and want to check.
For me, when I restore power to the clock the display starts blinking and the seconds advance two at a time. The clock also seems to lose several minutes of time while unplugged but it doesn't reset completely. I've checked the backup battery and it reads 3.17 V, which I think is good.
When power is present all the functions of the clock work as expected and it keeps good time.
Before I start trying to diagnose problems, can someone tell me how a properly working clock should behave on loss of power?
