Remove the battery and install the new one.   Be sure polarity is correct.

As to installing  the tuner into your Orion II, radio power off, remove the battery from the tuner to be installed, install the tuner in the Orion II, install the battery in the tuner.  Be sure polarity is correct and the connectors are correctly and fully inserted.

Hi folks,

I have just short question regarding the CR2032/2025 battery replacement in the 
AT566K internal antenna tuner in O2...
Can I simply remove the old one and replace with new cell or should I bypass 
the power pins with 3V PSU at first in order to not disconnecting the supply 
voltage from the tuner board?

The similar question I have when I will be installing this tuner into my O2...
Should I install it with battery in or should I remove the battery during the 
installation please?

(it is a bit contradicting to the first point, hihi)

Thanks for hints,

73 - Petr, OK1RP
