KEY:
Receiver measurements in wide FM mode. See
Table 2 for narrow mode.
Bars off the graph indicate values under scale.
You'll hear the audio received by the
radio the same way it's received by a
cellular phone. By default, when acti-
vating a Bluetooth audio device, the
speaker and microphone inside the
radio are deactivated.
Pairing a Bluetooth device was
straightforward. The radio can con-
nect only one Bluetooth audio device
at a time, so if your earbud is in your
pocket and connected to your radio,
this could cause confl ict when trying
to connect your Bluetooth to the car's
audio system.
I tried two different setups during my
tests. The fi rst one was a PlayStation
Bluetooth headset borrowed from my
