Basic functions
If you make a call using the handset and place it in the charger cradle, the hands-free operation
feature is automatically activated.
Do not hold the handset up to your ear in handsfree mode or when the ringer is ringing as the
volume can be very loud.
Acknowledging an appointment/alarm clock
You are notified of an appointment or alarm clock by the specified ringer and the LED flashing red
for approx. 45 sec. The display shows the corresponding text. You can acknowledge the signalling
with Esc.
