SELECTING THE ACTIVE PHONE NUMBER
Every cellular telephone has at least one NAM (Number Assignment Module),
which is used to store its phone number.
Your phone has two NAMs. If you subscribe to two cellular services (for
example, competitive cellular systems in your area or cellular systems in
different cities), each of your phone's NAMs was programmed with a
different phone number at the time of activation.
If your phone is programmed with two different numbers, follow these steps
to select the active number (the number you want to use to make and
receive calls).
1. Press [MENU], then repeatedly press [/\] or [\/] until the phone
displays NAM SELECT.
2. Press [OK]. The phone displays the active phone number.
3. Press [/\] or [\/] to select the other number, then press [OK] to
store your selection.
Notes: You cannot change the active number during a call. If you try to,
the phone displays CALL IN PROGRESS and exits the menu.
If you want to receive calls on both numbers at the same time and
you subscribe to call forwarding through your cellular service
providers, you can set both numbers on your phone to forward to
the other number if not answered. Contact your cellular service
providers for details.
SETTING THE CELLULAR SYSTEM TYPE
Every cellular market area has two cellular service providers. One of the
providers is designated Provider A and the other Provider B. Your phone
is activated to operate based on your cellular service provider's
designation (A or B). If you travel to a city where you do not subscribe
to cellular service, however, you can select any of these system settings
on your phone (based on how you want the phone to operate in that city).
Notes: Using the phone in a city where you do not subscribe to a cellular
service is referred to as roaming. See "Roaming" below .
The designation (A or B) that appears with the setting is based on
the selected phone number's NAM.
Usually it is less expensive to use the same provider type for
cellular service when you are in your home city and when you roam.
To do this, you need to know whether your cellular service provider
is type A or B in your home city and in each city where you plan to
travel.
It is possible for a cellular service provider to be (or have
agreements with) Provider A in some cities and Provider B in
others.
HOME TYPE (A or B) - Use this setting if you are roaming and your home
city cellular service provider is the same
provider type as in the city you have traveled to
(for example, if the company is Provider A in
both cities.)
NON-HOME TYPE (A or B) - Use this setting if you are roaming and your home
city cellular service provider is the opposite
provider type from the city you have traveled to
(for example, the company is Provider A in your
home city and Provider B in the other city).
HOME AREA - Use this setting if you do not want to roam (you
can only use the phone within the area covered by
your home cellular service provider).
BOTH SYSTEMS - Use this setting if you want the phone to use
either Provider A or Provider B. The phone uses
its home type system when possible and the
non-home type system when service is not
available on its home type system.
Follow these steps to set the cellular system type.
1. Press [MENU] [5JKL]. The phone displays the current setting.
2. Repeatedly press [/\] or [\/] until you see the setting you want to
use, then press [OK] to store that setting.
ROAMING
Using the phone in a city where you do not subscribe to a cellular service
is referred to as roaming. When you roam, ROAM turns on steadily if the
phone is using its home type system and flashes when it is using a
cellular system that is different from your home type system (non-home
type system).
In some areas, the cellular system's computer automatically recognizes
roaming telephones. In other areas, you must contact the service provider
before it can recognize your phone. The operator needs to know your
telephone number, your phone's ESN (Electronic Serial Number), and how you
plan to pay for your calls. There is normally an additional charge for
roaming calls.
Note: Your phone's ESN is under the phone's battery. (However, the roaming
cellular service providers can usually automatically determine your
phone's ESN when you call.)
SID SCREENING
If two different cellular market areas are located close to one another, a
call designated for the (A or B) carrier in one market can sometimes be
placed using the A (or B) carrier located in the other market area. This
can result in unwanted roaming and higher charges.
At the time of activation, a code is programmed into your phone that
uniquely identifies your cellular carrier. to prevent unwanted roaming,
your phone's System Identity (SID) screening feature lets you set your
phone to look for your designated carrier's code signal each time you
place a call, so the calls you place use only your carrier.
Notes: If SID screening is set to ON and the phone cannot locate your
designated carrier's code signal, only emergency calls to the
emergency number programmed into your phone can go through. Other
calls will not go through, and the phone will not roam. NO SVC
appears (with NO flashing).
When SID screening is set to OFF, your phone automatically roams
according to the selected cellular system type (see "Setting the
Cellular System Type" above).
Follow these steps to turn SID screening on or off.
1. Press [MENU], then repeatedly press [/\] or [\/] until the phone
displays SID SCREEN.
2. Press [OK]. The phone displays the current setting (SID SCRN ON or SID
SCRN OFF).
Note: If no SID information has been programmed into your phone, the
message NOT ALLOWED appears and the phone exits the menu.
3. Press [/\] or [\/] to select the other setting, then press [OK] to
store your selection.
The phone prompts you for your 4-digit lock code (LOCKCODE?).
4. Enter your lock code, then press [OK].
Note: If you enter the wrong lock code, the phone displays CODE ERROR.
Start again at Step 1 and enter the correct code.
SPECIAL PHONE SERVICES
CALLING LINE ID
If you subscribe to calling line identification service with your cellular
carrier, your phone is preset to automatically display the caller's phone
number (if available) each time it receives a call. If you stored the
caller's phone number with a name in the phone's memory (see Storing a
Number and Name in Memory" in Faxback Doc. # 46087) that stored name
appears.
HINT: To quickly store the displayed caller's number into the first empty
speed-dial memory, display the record then hold down [OK] for about
2 seconds (see "Using Number Quick Store" in Faxback Doc. # 46087).
MESSAGE WAITING
If you subscribe to voice mail service with your cellular carrier, calls
you do not answer are sent to your voice mail. A voice mailbox is
somewhat like an answering machine, because you must call it and enter a
password or personal identification code to listen to your messages. (For
information about using your voice mailbox, contact your cellular
carrier.)
When your phone is turned on and receives voice mail notification from
your cellular carrier, it displays (symbol) to notify you that you have
one or more messages waiting in your mailbox. When you call your mailbox
and listen to your message(s), (symbol) disappears.
HINT: If you subscribe to voice mail service, you can store the number you
call to reach your mailbox in your phone's one-touch dial location
(Memory 1) for easy access. See "Storing a Number and Name in
Memory" in Faxback Doc. # 46087.
OTHER SERVICES
Your cellular service provider might offer other special options that let
you receive or make a second call or conference two calls together using
your phone's [SEND] key.
Contact your cellular carrier for details about these special services or
billing.
