Turning on your phone.

Of course, before you can use your Sprint PCS Phone you'll need to turn it
on.  Start by checking to see that the charged battery is installed or
that you have an external power source (the rapid cigarette lighter
adapter or the hands-free car kit).  Then, simply press [PWR] until the
red light flashes briefly and the greeting screen is displayed.  Now
you're ready to make a call.

Turning off the phone is just as simple.  Press [PWR] for two seconds.
The display will be blank when the power is off.

Phone calls:  How to make and receive them.

Whenever you make a call, follow these simple steps:

1.  First, check to see that your Sprint PCS Phone is turned on and that
    you are in a Sprint PCS Service Area.  If you see the display icons on
    the screen, that means the power is on.  Unless you see NOSVC on the
    display screen, you are in a Sprint PCS Service Area or another
    provider's service area.

2.  Enter the number you're calling.

3.  Press [TALK].

4.  When you're finished with your call, just press [END] or close the
    flip to disconnect.

Speed dialing

Speed Dial allows quick access to numbers stored in the internal phone
book.  Memory locations 1 through 9 are for one-touch dialing: just press
and hold the corresponding number key and the phone will dial
automatically.  For locations 10 through 99, enter the first digit of the
memory location, then press and hold the second digit.  (For detailed
information about storing numbers in memory, refer to Faxback Doc.
# 48401.)

Correcting a mistake.

If you make a mistake while entering a phone number, press [CLR] to erase
the number one digit at a time.  To delete the entire number at once,
press [CLR] and hold it down for at least one second.

Remembering your phone number.

You probably don't call your own Sprint PCS Phone Number very often, so
you may forget it.  If you do, here's an easy way to find it: Turn your
phone on and your number will be displaced briefly.

If you miss it, press [MENU], press [5] to select "Display" and then press
[2] to display your number.

Answering calls.

When your phone rings, simply open the flip to answer.  If the flip is
open when the phone rings, just press [TALK].  To disconnect when you're
through, press [END] or close the flip.  You can customize your options for
answering calls using the Any Key Answer feature on the Setup menu.
(Press [MENU] and [8] to select the Setup menu, then press [2] to access
Any Key Answer.)  This allows you to press any key, except [PWR], [END] or
the volume keys, to answer a call when the flip is open.

To turn off your phone's ringer without disconnecting the incoming call,
press the volume key or press [END] when the flip is open.

Your phone's red light will flash continuously until the call is ended or
forwarded to your voicemail.

Using Caller ID.

This feature tells you who is calling by displaying the caller's number
when the phone rings.  If the caller's name and number are stored in your
internal phone book, the caller's name will be displayed, too.  If you
call someone who also has Caller ID, your Sprint PCS Phone Number will be
displayed on their phone.

To block your Sprint PCS Phone Number from being displayed for a
particular outgoing call, just follow these steps:

1.  Press [/\*] [6] [7].

2.  Dial the outgoing phone number and press TALK.

To block your Sprint PCS Phone Number from being displayed on all of your
outgoing calls, call Sprint PCS Customer Care by pressing [/\*] [2] [TALK]
(in Southern California, press [/\*] [6] [1] [1] [TALK]).  Once you have
permanently blocked your number, you can release the block for a
particular call.  To do that, follow these steps:

1.  Press [/\*] [8] [2].

2.  Dial the phone number and press [TALK].

Responding to Call Waiting

When you're in the middle of a call, you will be alerted to other incoming
calls with a short beep and a "CALL WAIT" message.  With Caller ID, the
phone number and name (if stored in your phone book) of the caller are
also displayed.  If you don't answer the call within ten seconds, you will
be reminded of the incoming call with a second beep.  To put the first
call on hold and answer the second call, press TALK.  Press [TALK] again
to switch back to the first call.

If you don't want to be interrupted during a particular call, you can
temporarily disable Call Waiting.  Just press [/\*] 7 0 before dialing the
number.  Once you end that call, Call Waiting will be reactivated
automatically.  If you don't want to be interrupted during any of your
calls, press [/\*] [2] [TALK] (in Southern California, press
[/\*] [6] [1] [1] [TALK]) to call Sprint PCS Customer Care and have Call
Waiting deactivated.

Redialing calls.

To redial the last number you called from your Sprint PCS Phone, press
[TALK] [TALK].  To redial any of your last nine outgoing calls, display
the outgoing call log by pressing [TALK], use the arrow keys to select the
number and then press TALK again.  The most recent call is displayed
first.

Setting up Three-Way Calling

Three-Way Calling lets you talk with two people at the same time.  Simply
dial the first number and press [TALK].  When you have connected, press
[TALK] to put the first party on hold.  Dial the second number and press
[TALK].  When the second party answers, press [TALK] again to begin your
Three-Way Call.  When you use this feature, you will be charged normal
airtime rates for both calls.

Using Call Forwarding.

With Call Forwarding, all of your incoming calls can be forwarded to
another phone number -- even if your Sprint PCS Phone is turned off.  You
can continue to place calls from your Sprint PCS Phone when Call
Forwarding is activated.  To activate Call Forwarding, follow these steps:

1.  Press [/\*] [7] [2].

2.  Enter the ten-digit phone number (area code + phone number) of the
    forward-to phone number.

3.  Then press [TALK].  You will hear a confirmation tone.

To deactivate Call Forwarding, press [/\*] [7] [2] [0] [TALK].

Saving or editing your own emergency numbers.

You can save up to three emergency phone numbers on your Sprint PCS Phone,
in addition to 911.  To save those numbers, follow the steps below.

1.  Press [MENU].

2.  Press [6] to select "Security."

3.  The phone prompts, "Lock Code:"  Enter your four-digit lock code
    (unless you've changed it, this code is typically the last four digits
    of your Sprint PCS Phone Number).  Once you've successfully entered
    your lock code, the phone displays the Security menu.

4.  Press [4] to select "Emergency#."  The phone displays your emergency
    numbers.  (If no emergency numbers have been saved, "Empty" is
    displayed in each slot.)

5.  Select an emergency number slot by pressing the appropriate number.

6.  Enter the ten-digit emergency number (area code + phone number) to be
    saved in that slot and press [OK].

7.  The phone displays the number and "Saved" to confirm that the number
    was stored correctly.  The phone then redisplays the list of emergency
    numbers so you can make additional changes.

8.  When you have finished storing numbers, press [END] or press and hold
    [CLR] to exit and return to the standby display.

Dialing 911 or other emergency numbers

You can call 911, your stored emergency numbers or Sprint PCS Customer
Care even when your phone is locked.  (For information on locking your
phone, see Faxback Doc. # 48402.)

1.  Dial 911, one of three emergency numbers stored in your phone or press
    [/\*] [2] (in Southern California, press [/\*] [6] [1] [1]).  You must
    dial your emergency numbers exactly as you have stored them.

2.  Press [TALK].

Note:  You cannot dial your three emergency numbers when your Sprint PCS
       Account has been restricted for credit purposes.  You can call 911,
       however.
