Adjusting the Ear-piece Volume
The volume of the ear-piece can be controlled by scrolling /\ \/ during a
call when the display is clear. Press /\ to increase and \/ to decrease
the volume level.
Note: These keys act as scrolling keys for the memory and the menu
functions when not in a call.
Last Number Redial
The last five numbers you called or attempted to call are stored in the
phone's memory location 0 (LO-L4). This stack of the five last dialed
numbers remains in the phone's memory when the phone is switched off.
To redial a last dialed number:

phone directory, first press ABC and then start scrolling by using
/\ \/. The location number is displayed in the upper right corner of
the display (LO-L4).
If the stack of the last dialed numbers is empty, the message LOCATION
EMPTY will be displayed.
3. To make a call to a displayed number or name, press SEND.
See also Dialed Calls Memory Location below.
Speed Dialing
Speed dialing is a handy way to call frequently-used phone numbers stored
in the phone directory locations. (To store phone numbers, see Storing
Names and Phone Numbers below.)
1. Enter the number of the memory location containing the desired phone
number.
2. Press SEND.
The phone recalls the phone number from the specified memory location,
displays it briefly, and then dials it.
If the memory location is empty, the message LOCATION EMPTY will be
displayed.
1 Touch Dialing
If the menu function 1 TOUCH DIALING (Menu 9) is set to on (1 TOUCH ON),
you can make a one-touch dialing call to the number (e.g., your voice-mail
number) stored in phone directory location 1 by pressing and holding the 1
key.
To store the number in the phone directory location 1, see Storing Names
and Phone Numbers below.
9 Key Emergency Dialing
If the menu function Emergency Key 9 is set to on (EMERG. 9 ON), you can
make an emergency call to the emergency number programmed into your phone
by pressing and holding the 9wxyz key.
The phone dials the emergency number programmed into your phone and
displays the message EMERG. CALL TRY.
Note: Official emergency numbers vary by location (e.g., 911 or another
official emergency number). However, only one emergency number is
programmed into your phone to be dialed automatically by one-touch
emergency dialing, which may not be the proper number in all circum-
stances.
Note: The 9 key Emergency Dialing does not operate when the Keyguard
feature is activated.
However, an emergency call can be made without deactivating the
keyguard by entering the whole emergency number programmed into
your phone and then pressing SEND.
To make an emergency call when the keyguard is activated:
1. Enter the emergency number programmed into your phone and press SEND.
The emergency number is displayed only after you have entered the last
digit of the number.
The phone dials the emergency number programmed into your phone and
displays the message EMERG. CALL TRY.
Keyguard
The phone's keypad may be locked to prevent unintended key presses from
being made when the phone is in a pocket or a bag.
No security code is required to activate or deactivate the keyguard feature.
To activate the keyguard:
1. Press MENU and then *. You can also activate the keyguard by pressing
and holding END (e.g., when ending a call).
The message KEYGUARD ACTIVE remains on the display until the keyguard is
deactivated.
When you press a key, the phone prompts you to press the MENU key.
To deactivate the keyguard:
1. Press MENU (at PRESS MENU prompt) and * (at NOW PRESS * prompt).
The message KEYGUARD OFF is briefly displayed indicating that the keyguard
has been deactivated.
When the keyguard is activated:
To answer a call, press SEND. During the call the keypad remains
unlocked and the phone can be operated in the normal way.
To end a call, press END. After the call is ended, the keyguard
automatically becomes active again.
The phone can not be switched off before the keyguard is deactivated.
Note: When the keyguard is activated, calls may be possible to the emer-
gency number programmed into your phone (e.g., or another official
emergency number). However, one-touch emergency dialing ('the 9
key') does not operate.
Calling Card Call
When making a long distance call, the call charges can be directed to a
a selected long distance phone company if the card number is sent to the
network during the call setup.
Before making an automatic calling card call, you have to activate one of
the calling card options from the menu function CALLING CARD.
To make an automatic calling card call:
1. Enter the area code and phone number and press and hold SEND for more
than one second.
The message CARD CALL remains on the display until the access number
has been sent to the network. The phone asks you to wait for a tone
(WAIT FOR PROMPT).
2. After the tone, press SEND.
The phone now sends the phone number to the network and the message
CARD CALL remains on the display until the transmission is completed.
The phone prompts you to wait for another tone.
3. After the tone, press SEND once again.
The phone now sends the card number to the network and the message
CARD CALL remains on the display until the transmission is completed
and the phone returns to the normal call mode.
Note: This procedure may not apply to all calling card options pro-
grammed into your phone. Please contact your local service
provider or the appropriate long distance phone company for
further information.
4. Using Phone Directory
Standard Memory Locations
Your phone has 40 alpha-numeric phone directory locations. Memory locations
1-20 (short) can hold phone numbers of up to 16 digits and names of up to
16 characters. Memory locations 21-40 (long) can hold numbers of up to 32
digits and names of up to 16 characters.
Note: If you try to store a digit string greater than 16 characters in a
short memory location (locations 1-20), the message DIGITS MAX = 16
is briefly displayed and the phone exits the store function. The
string you tried to store will reappear on the display and you can
store it in a long memory location.
Dialed Calls Memory Location
Memory location 0 is reserved for the stack of the five last dialed numbers.
The phone automatically stores the five last dialed numbers in the memory
location 0 (LO-L4). Whenever a new call is made, the last dialed number is
stored in the location LO, and the other numbers in the stack are moved for-
ward by one location so that the number in the location L4 is overwritten
after the sixth call is dialed.
A phone number cannot be stored twice in the stack. When dialing a num-
ber that already exists in the stack, the dialed number is moved to the
top of the stack (i.e., it is stored in the location LO).
1. To view the stack of the five last dialed numbers press SEND (with the
display clear) once. Use /\ \/ to scroll the last dialed numbers.
To view the associated names, if the dialed calls were made from the
phone directory, first press ABC and then start scrolling by using /\
\/. The dialed calls location number is displayed in the upper right
corner of the display.
If the stack is empty, the message LOCATION EMPTY is displayed.
2. To make a call to the displayed number or name, press SEND.
To erase the stack, erase the memory location 0 (LO-L4) as described in
Erasing a Memory Location below.
Notepad Memory Location
In addition to the standard phone directory locations, your phone has one
short term memory location, where a phone number can temporarily be stored,
e.g., during a call. This location is automatically cleared when the phone
is switched off.
To store a number in the notepad memory:
1. Press STO.
The phone prompts you to enter the name to be stored (NAME?).
2. Enter the name (as described in Entering Names below) and press STO (or
just press STO if you do not want to store a name).
The phone prompts you to enter the phone number (NUMBER?).
3. Enter the area code and the phone number and press STO.
OR instead of the steps 1 to 3 above, enter the area code and the phone
number and name to be stored and then press STO.
The phone suggests the first empty memory location if available (STORE
TO 5?).
4. Press # and then STO.
The phone will store the number (and name) in the notepad memory location.
Any number previously stored in the notepad memory will be overwritten.
To recall the number from notepad memory:
1. Press RCL first, then enter # as the location number and confirm by
pressing STO (or press # first and then RCL).
If the location is empty, the message LOCATION EMPTY will be displayed.
2. To call the number, press SEND.
To store the number (and name) from the notepad memory location in a memory
location, recall it, then store it as described in Storing Names and Phone
Numbers below.
