Pin Name

Function

Beep and traffic information alarm output pin.

I/O Format

q Beep sound

Outputs square wave with frequency of 2.25 kHz and duty

factor of 50 % for about 40 ms.

This time is equal to forward mute time.

Beep sound is issued when:

• Analog key is pressed and tuning operation is started.

Beep and

signal output When it is specified that beep sound is not to be issued

(when BEEP switch of initial setting diode = 0 (open)), no

sound is issued.

q Traffic information alarm

When traffic information station identification signal is

missing for about 3 seconds after SK mute output in TP/SK

or RDS+TP/SK mode of FM band, outputs alarm sound

with frequency of 900 Hz intermittently for about 0.5 second.

If this pin is not used, leave it open.
