I would purchase the forerunner 245 music, but I'm wondering if we can disable the connections (the wifi and the bluetooth) of the watch when we run and don't use it. I don't find the answer in the manual.
Thank you for your help.
On the controls screen (hold down the power button), there should be an option to disconnect from the phone (airplane mode). i don't know if you can specifically turn off wifi, but it's not used unless it's actually needed, like downloading music. If you don't download music, and if you are connected to your phone with BT when you sync an activity then wifi probably never comes on at all.
Just my opinion, I'd suspect the bigger use of BT would be the daily step tracking and notifications. Running would be a pretty small amount of power usage. Probably just the activity sync at the end.
