Sony MDR-7506 Service Manual page 10

Mustang Micro easily streams Bluetooth audio, so you can play along in your headphones
or earbuds. The device is discoverable as "Mustang Micro" on smart phones and other
Bluetooth devices.
To activate Bluetooth pairing mode, push the POWER SWITCH (G) to the left, where the
Bluetooth symbol is, and hold it there for two seconds. The POWER SWITCH Bluetooth
position is spring-loaded for momentary contact only, and will return to the center "ON"
position when button is released. In pairing mode, the POWER SWITCH LED will flash blue
for two minutes or until a connection is established.
On successful connection, the LED will turn solid blue for 10 seconds and then extinguish.
To disconnect a Bluetooth device from Mustang Micro, hold the POWER SWITCH in the Bluetooth position for two
seconds and then release it (as when pairing). This will end the Bluetooth connection and return Mustang Micro to
pairing mode with a flashing blue LED; pairing mode will expire within two minutes if no other Bluetooth connection
is made, and the blue LED will extinguish. Alternately, disconnect using the external device.
Mustang Micro automatically pairs with the last connected Bluetooth device if that device is available. Note that MAS-
TER VOLUME (B) controls instrument and overall volume only; the mix between an instrument and a Bluetooth audio
source is determined using the volume control on the external Bluetooth device.
Mustang Micro provides up to six hours of battery-powered operation. Recharge Mustang
Micro using the USB-C jack (H) on the bottom of the unit and the included USB cable.
