Buzzer
Alerting tones and/or melodies as a signal of an incoming call are generated with a
buzzer that is controlled with a PWM signal by the MAD via UISWITCH. Also key press
and user function response beeps are generated with the buzzer. The buzzer is a SMD
device and is placed on the mother board. Target for SPL is 100dB (A) at 5cm.
