Polar 115 Plus

Hello,

I want to replace the battery on Polar 115 Plus. Is there any risk of losing all programs or parapeters?
Should I just turn off the main voltage, remove the board and replace the battery or is it better to do it under the voltage ?

Thanks you in advance.

 

Hello
There is always a risk to lose the programs. To be on the safe side, I recommend to apply 3.6V to battery connection on CP module (observe the polarization) and then the replace the battery. And of course you should take out the module.

 

Okay thank you for your help. I will do that.

 

No sir dont replace the battery under the voltage
You must do it very quickly if you If you delay more than 20 minutes there is a risk of losing the program
