PAUSE DIALING
PAUSES - FCN + 9. This function creates pauses while
sending out DTMF signaling tones during conversation
mode. When a manual pause is encountered in the DTMF
string, the phone will pause indefinitely, until the user
presses the SND key.
More than one pause may be placed in a sequence,
seperating several groups of DTMF digits.
For example, this function may be used for calling a paging
system and sending commands, ID numbers (PIN), and/or
numeric messages:
(1)
(2)
(3)
(4)
(5)
“123456789” + “P” + “123456789#” + SND + SND
(1) This is the phone number to be called via the cellular system.
(2) This character indicates a Manual Pause. The user will
wait for the initial prompt from the paging system before
pressing the SND key.
(3) This is a DTMF digit sequence which may represent
the PIN of the called pager.
(4) This is the initial send keypress which causes the phone
to initiate a call using the number up to the first pause mark.
(5) This is the second send keypress, while in conver-
sation mode, which will end the manual pause and start
the sending of DTMF digits.
ROAMING (SYSTEM SELECT)
Each cellular service area can have two cellular service
suppliers called carriers. One carrier is called the ‘non-
wireline’ or ‘A’ system and the other carrier is called the
‘wireline’ or ‘B’ system. Your phone is designed to work
with either or both carriers. The system priority feature
allows you to program your phone for optimum operation
when in your home serving area or when away from your
home area. This is called roaming. When you buy your
phone, you may register (receive a phone number) with
either or both of your local carriers. Contact the office of
your home cellular phone company for information about
the roaming agreements they have with other cellular phone
companies. In some areas, roaming telephones are auto-
matically recognized by the cellular system’s computer. In
other areas, you must contact the cellular phone operator
before it can recognize your phone. The company needs
to know your telephone number, your phone’s ESN (elec-
tronic serial number), and how you plan to pay for your
calls. There is usually an additional charge for roaming calls.
Note: The ESN for your phone is located in the battery
compartment of the phone, and comprises the first
8 digits preceeded by NEC’s company code of 189.
