For example, this function may be used to link individual long-
distance recall numbers to a single recall number which holds
credit card information. The primary recall number(s) would
contain the link information:
Recall #01
(1)
(2)
(3)
(4)
"123456789" + "L" + "99" + SND
(1) This is the phone number to be called via the cellular
system.
(2) This is a linking mark which indicates that the following two
digits represent the recall number to be linked.
(3) This is the number of the memory recall location to be
linked, and therefore treated as DTMF signalling.
(4) This is the Send keypress which causes the phone to
initiate a call.
Note: Once the call is placed a pause is automatically
inserted and the user must press the SND key in order to
output the linked DTMF sequence.
System Selection (Including Roaming)
Each cellular service area can have two cellular service
suppliers called carriers. One carrier is called the 'A' system
and the other carrier is called the '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
automatically 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 (electronic
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 of the first 8
digits preceded by NEC's company code of 229.
