How do I increase or decrease the PC volume using the Havit Gamenote KB903L keyboard?

The Havit Gamenote KB903L is a 60% layout keyboard, which means many standard functions are accessed through the Fn key (located on the bottom row, to the right of the right Alt key).

While the provided manual text specifically lists shortcuts for lighting and navigation (like Fn + [{ for brightness), it does not explicitly list a dedicated volume shortcut. However, on most Havit 60% keyboards, media functions are typically mapped to the following combinations:

• Volume Up: Try Fn + S or Fn + F11 (which is Fn + 0 on this model).
• Volume Down: Try Fn + A or Fn + F10 (which is Fn + 9 on this model).
• Mute: Try Fn + F9 (which is Fn + ( on this model).

If these combinations do not work, please check the legends (icons) printed on the side or front of your keycaps, as Havit often prints media icons (like a speaker symbol) on the keys that perform those functions when held with Fn.
