Acurite only broadcasts on C channel

My Acurite 5n1 is stuck broadcasting on channel C after a battery change. This occurs no matter which position the inner switch is set to, C is all I get. Home Assistant no longer detects the device as well. All my other MQTT sensors are operating as expected.

Appreciate any help, thanks!
