When other functions are mapped onto the keys, the LEDs may glow or blink. For example: When the
"extension" function has been mapped onto a key and monitoring of extensions is enabled on both phones, the
LED will:
• blink rapidly when a call is ringing on the extension;
• glow steadily when the extension is busy;
• be off when the extension is not busy
