Philips Onis 2 - Manual (Page 28)

Your Phone book and emergency number 24
Calling the emergency number
To call an emergency number, press S and the number is dialled automatically.
Note:
1. The S key works only if your handset is charged and your base station is
correctly plugged in.
2. If you have not entered an emergency number, pressing S will be ineffective
as there is no pre-programmed number.
3. On your Oniso o Memo, there is no S key. The only way to store an
emergency number is to store it in your phonebook. To call this emergency
number, follow the procedure “Making a call using the phone book” on page 23.
Tip
You can use the S key to store your most frequently called number.
