If the UPDATE button doesn't light up on your SRS-HG1 Bluetooth® speaker when the LINK indicator is on, check the following:
- Make sure the speaker is connected to the power outlet with a USB AC adapter.
Note: The software update isn't available if the speaker uses the built-in battery.
- Check the speaker's software version from the settings of the Music Center (SongPal) app.
Note: The UPDATE indicator doesn't light up if the system software has the latest version.
