Sanyo PRO-700 User Manual

If the person you are calling has a separate number for
Direct Connect, make sure you dial any asterisks (*) in the
number. If you are saving the number in your Contacts,
choose DC Only for the phone type.

If the person you are calling has a single number for both
voice calls and for Direct Connect, use that 10-digit phone
number to make Direct Connect calls. You do not need to
add any asterisks (*) to the number. If you are saving this
number in your contacts, choose Mobile + DC for the 
phone type.

Check the icon for the highlighted number. 
If it has a 

and 

icon, it is a valid DC number.

– or –
Select a contact and press  . “DC capable”will appear
below the valid Direct Connect number.

Users with a Nextel phone must always add asterisks (*)
between digits to dial Direct Connect numbers. If you use a
single number, make sure to tell your contacts with Nextel
phones to dial the 10-digit number using asterisks (*) in place
of hyphens (for example, 44*5555*111).

One way to easily ensure that your contact has your correct
number is to call them so that they can save your number
from their Call Log. Ask them for their contact information.
Remember you will need all digits of the number to make a
successful call. Also, if they have a Nextel phone or a separate
number for Direct Connect, you will need to enter asterisks (*)
between sets of numbers.
