Replace backup battery CR2032 in a K3

Steef PA2A
Hi,

has anyone already changed the CR2032 backup battery in a K3? Under the
carton cover the battery has started to oxydize but the Voltage is still
3.06 Volts after twelve years. I guess an external 3 Volts source should
be applied to save all settings during the replacement.

The battery supports the real time clock only.  You won’t lose any other settings if you replace it.

Don’t get too excited. I’m told it only keeps the clock running. All settings are in non-volatile  memory.

Grant,

thanks! I did not know that, or had already forgotten this twelve years
after assembling the rig. I was also thinking that a backup and restore
of the settings would be sufficient. I am going to replace it soon.
