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!
