Date Time does not stay

[smesterj]

Hi guys, everything working fine except the date and time does not stay after I power off the transmitter, before I install the board I bought a new battery and placed in, though that will keep the clock running all time.

It should.. are you sure the battery is good? Did you measure the voltage?

Or installed upside down? The lettering on the battery should face "out"

Battery was dry, new one solved it.
Date and time good now, Thanks!!!!
