on the steering wheel. Aftermarket radios that do not have Bluetooth
will not recognize the PTT (Push To Talk) or “On/Off Hook”
commands; however those buttons can be manually programmed
to do other commands in some cases. Please refer to the radio

Note: Not all radios will have all of these commands. Please refer to the
radio owner’s manual or contact the radio vendor directly for specific
commands recognized by that particular radio.
If the next function on the list is not on the steering wheel press the
“Volume Up” button for 1 second, until the LED comes on, then release the
button. This tells the ASWC-1 that the function is not available will move on
to the next function.
*Note (section B): If the ASWC-1 flashes 7 times and you do not have an
Alpine radio connected to it that means that the ASWC-1 did not see any
radio connected. Verify the 3.5mm connector is connected to the SWC
input on the radio.
