Sony NPA-MQZ1K Multi Battery Adapter Kit - Manual (Page 130)

Remote controls with a Google Assistant/MIC button are connected to the TV using
Bluetooth. Radio interference may occur in the following situations and cause issues
such as poor operation of microphone or remote control because Bluetooth radio
waves use the same frequency as radio waves emitted from microwaves and
wireless LANs.
There are people or obstacles (such as metal objects or walls) between the TV and remote
control.
A microwave is being used nearby
There is a wireless LAN access point nearby
The TV and remote control are unpaired
In these cases, try the following solutions.

Remove obstacles between the TV and remote control
Use the remote control when a microwave is not in use

used to operate other TVs. When checking remote control operation, use with the TV
