Quick Tips

  • Use the arrow keys to switch between EXP50 pages if you run out of buttons.

  • To edit or change a button → hold it down again.

  • Labels help you remember what each key does — keep them short (e.g., “HR,” “Mgr,” “VM”).

  • BLF keys light up to show real-time status:

    • 🟢 Green = Available

    • 🔴 Red = On a call

    • ⚪️ Flashing = Ringing

👉 Now you can program, label, and use your EXP50 like a pro!
