3 Start playback on the Walkman connected to the transmitter.
e music of the Walkman is played back on the headset.
Tip
You can control the volume on the headset. You can also fast-forward or fast-
rewind while playing back (page 16).
Notes
Depending on your Walkman, when it is in Sleep status, you may need to keep
pressing the play button in order to start playback.
Even if you control the volume on the Walkman, sound from the headset will not
change. If the Bluetooth receiving device is supported by AVRCP (Vol +/–), you
can control its volume.
When this transmitter establishes the Bluetooth connection with the Walkman,
AVLS (Automatic Volume Limiter System) is deactivated and beep sounds are
not emitted.
If the transmitter and the headset become out of range and the Bluetooth
connection terminates, repeat the procedure from step 1. Note, however, that if
the transmitter and the headset come into connectable range again within about
10 minutes, the Bluetooth connection will be reestablished automatically.
To listen to an FM broadcast received by a Walkman with a built-in FM tuner
through the headset, make sure to connect the Walkman’s headphones, as its
cord works as an antenna, otherwise FM signals cannot be received.
If the recording level of audio data on the Walkman is too high, the output
sound quality from the headset, may not meet the user customized settings, e.g.,
“Equalizer” etc.
Playback through a Bluetooth connection may cause noise, sound break, or
playback speed change depending on the location and the usage (page 27).
About the MODE switch on transmitter
You can select the sound quality or wireless communication stability preferentially.
MODE 1: Sound quality takes priority.
MODE 2: Reception stability takes priority.
Notes
When you set the MODE switch to MODE 1, and experience sound breaks, set
to MODE 2.
Sound break may occur depending on your Bluetooth receiving device when
switching between MODE 1 and 2.
