To achieve maximum volume with the SRS-HG1:
- Fully charge the battery.
- Connect using the Bluetooth® connection rather than using Audio In.
- Maximize volume setting on the music player (e.g., smartphone, MP3 player), as well as on the SRS-HG1.
- Use the SongPal app to set the Equalization setting to OUTDOOR.
- Open the Songpal SETTINGS menu.
- Select SOUND.
- Select EQUALIZER.
- Select OUTDOOR.
NOTE: To maintain maximum volume while using the OUTDOOR equalization, Do NOT press the EXTRABASS button. Doing so will increase the bass but reduce the overall sound level.
