SOS in case of emergency

Misalnya kamu dalam keadaan darurat, kecelakaan, penodongan, perampokan, dan butuh pertolongan, buatlah nada SOS berkali-kali.
Bisa bunyiin klakson mobil, klakson motor, atau kalau terpaksa bisa juga ketok-ketok di tembok atau di mana terserah.
Biasanya kalau mendengar bunyi SOS, polisi atau orang yang mengerti sandi morse akan mencoba membantu kamu.

Bunyinya seperti ini: (dalam sandi morse)

... --- ... ... --- ...
S O S, S O S

Keterangan:
. adalah nada pendek
- adalah nada panjang
spasi adalah jeda sebentar


Nah kalau pernah denger ringtone defaultnya Nokia, selagi dapat SMS, bunyinya begini:
... -- ...
S M S
