Please confirm the monitor model. Provide a link if possible.
I wanted to look at the monitor's specifications and its User Guide/Manual but my searches did not come up with a matching model number.
Tried some variations as well: e.g. "zero" vs "oh", "5" vs "S".
Key component is that the monitor have either built-in Bluetooth or a port for a Bluetooth receiver.
And it may be that a port is physically present but established only for future use; meaning no circuitry actually in place for the model at hand.
