CT-502 Handheld Flip-Style Cellular Telephone
(170-1111)                 Operation                  Faxback Doc. # 45996

Turning The Phone ON/OFF

To turn on the phone, flip down the cover then press PWR.  The phone
performs a short self test and sounds a tone or vibrates (see "Changing
the Alert Type" in Faxback Doc. # 45997), then the signal strength meter
appears (see "Signal Strength/Service Area") and the keypad backlight
turns on for about 16 seconds.  The phone is ready to use when the green
power/lock indicator begins to flash.

Notes:  The keypad backlight turns on for about 16 seconds every time you
        press a key, then it turns off and the display goes blank to
        conserve battery power.

        To turn off the phone, press PWR again.  The display goes blank and
        the green on/lock indicator turns off.

Signal Strength/Service Area

Each time you turn on the phone, clear the display, or make a call, the
signal strength meter appears on the display to indicate the strength of
the cellular signal currently being received.  The more bars that appear
on the meter, the stronger the signal.

Notes:  If few or no bars appear (meaning the signal strength is weak) and
        you want to make or receive a call, move the phone to a different
        location so the signal strength increases.

        You can disable the signal strength meter so it does not appear.
        See "Turning the Signal Strength Meter Off/On" in Faxback Doc.
        # 45997.

If the NoSvc indicator (above the display) turns on, the phone is outside
the cellular service area and you cannot make or receive calls until you
reach an area with service your phone can use.

Making a Call

1.  Extend the antenna, flip open the cover, and be sure the phone is on
    (the green power/lock indicator is flashing).

2.  Press the number keys to enter the phone number you want to dial
    (including the area code, if necessary).  The numbers appear on the
    display as you press them.

    Notes: If you make a mistake, repeatedly press CLR to delete one 
           digit at a time, or hold down CLR to delete all digits.

           The phone can display up to 7 characters at once. If you enter
           (or display a message containing) more than 7 characters, the 
           characters automatically scroll off the left side of the 
           display.  Press RCL at any time to recall the overflow 
           characters.  See "A Number Longer than Seven Digits" below.

3.  Press SND to dial the phone number.  The InUse indicator flashes and
    the phone briefly displays Dialing then the number called, then the
    signal strength meter.

4.  To end the call, press END.

Note:  Closing the cover does not end or disconnect the call.

System Busy Message

in addition to the normal busy signal you hear when a number you call is
busy, your phone sounds tones and displays a message to indicate other
situations when it cannot complete a call

Tone        Display Shows      Description

Fast Busy   SND to Redial      The cellular system is busy.

High/low    SND to Redial      The cellular system could not complete the
                               call.

When either of these conditions occur, you can press SND again to redial
the number immediately (see "Using Automatic Redial" below), or press END
then dial the number again.

Answering a Call

When the phone receives an incoming call, it rings or vibrates (depending
on the alert setting - see "Changing the Alert Type" in Faxback Doc. #
45997) and Call flashes on the display.  To answer the call, press SND.  
To end the call, press END.

Notes:  Your phone can receive calls even if the antenna is not
        extended.  For optimum performance or if the signal strength
        becomes weak, however, extend the antenna.

        To set your phone so you can answer a call by pressing keys
        other than just SND, see "Using Multiple Key Answer" in Faxback 
        Doc. # 45997.

        If you subscribe to calling line ID service through your cellular
        carrier, you can view the calling party's phone number on the 
        phone's display.  See "Viewing/Recalling Messages" in Faxback Doc.
        # 46000.

        If your phone receives a call but the signal strength is too weak
        to support it, Call appears as usual, but you hear the phone sound
        a series of beeps (rather than ringing or vibrating).  The caller 
        hears the standard "not in service" message.  If this happens, 
        press CLR to clear Call from the display.

Missed Call Message

If your phone is on and receives a call, but you do not answer it, Call
appears on the display for about 15 seconds after the calling party hangs
up.  The next time you press any key (except CLR, END, or PWR),  Call
reappears for about 15 seconds to notify you that you missed a call.

To clear Call from the display, press CLR or END.

Adjusting The Volume

Adjusting the Earpiece Volume

To increase or decrease the earpiece volume during a call, repeatedly
press the top (increase) or bottom (decrease) volume button on the side of
the phone.  Each time you press the button, the volume meter appears on
the display for about 8 seconds.  The more bars that appear on the meter,
the higher the earpiece volume.

Adjusting the Keytone and Ringer Volumes

To increase or decrease the phone's keytone volume, when the phone is not
in use, repeatedly press the top (increase) or bottom (decrease) volume
button on the side of the phone.  Each time you press the button, the
phone rings once and displays the volume meter for about 8 seconds.  The
more bars that appear on the meter, the higher the ringer volume sounds.

To increase or decrease the phone's ringer volume, when the phone is not
in use, press FCN then repeatedly press the top or bottom volume button.

Using Mute

To turn off the phone's microphone during a call so the other party on the
phone cannot hear you (so you can talk privately with someone else in the
room for example), press FCN key and MNO 6.  Mute appears.

To turn the microphone on again, press FCN and MNO 6 again so Mute
disappears.

HINT:  To help you remember which key to use, note that "M" (for mute)
       appears on the MNO 6 key.

Note:  Pressing END to end a call also turns the microphone back on.

Making Emergency Calls

Your phone is preprogrammed to let you dial your local emergency number
(such as 911) at the press of a single button, even if the phone is locked
(see "Locking Your Phone" in Faxback Doc. # 45999).  Before you can use 
this feature, however, you must first program the emergency number you 
want to use in memory location 01 of your phone, See "Storing Speed Dial 
Numbers" in Faxback Doc. # 45998.

To place an emergency call once you have stored the emergency number,
simply hold down 1 for about 1 second.  Emergency appears and the phone
dials the emergency number.

Important Notes:  If one-touch dialing is turned off (see "Turning One
                  Touch Dialing Off/On" in Faxback Doc. # 45997, you 
                  cannot make emergency calls using the 1 key.

                  When you make an emergency call, give your name and
                  cellular phone number, as well as the location of the
                  incident.  Remember that your phone might be the only
                  means of communication at the accident scene.  Do not
                  end the call until you are advised you may do so.

                  Emergency does not appear if the emergency display
                  function is turned off (see "Turning the Emergency 
                  display Off/On" in Faxback Doc. # 45997).

Redialing Numbers

Using Last Ten Number Redial

Your phone constantly stores the last 10 phone numbers you called.  To
recall and redial one of those 10 numbers, follow these steps.

1.  Press RCL, OPER 0, OPER 0. L0' (location 0) and the most recent number
    called flash on the display.

2.  To scroll through the last 10 numbers called (L0', L1' and so on),
    repeatedly press # -> to scroll forward or <- * to scroll backward.

3.  To redial a displayed number, press SND.

    To exit without redialing a number and clear the display, hold down
    CLR for about 1 second.

Using Automatic Redial

To automatically redial a number when you get the cellular system busy
signal (when Snd to Redial appears), press SND so Redial appears.  The
phone automatically redials the number at regular intervals for up to
4 minutes or until the call goes through.

If the call goes through, the phone rings once (or vibrates, depending on
the alert setting) to alert you.  Simply begin your conversation as usual
when the other party answers.

If the call cannot be completed within 4 minutes (and Snd to Redial
appears again), you can press SND again to repeat the redial cycle or END
to end the call.

Displaying Numbers

Your Phone Number

To display your phone number at any time (even while a call is
in progress), simply press RCL # ->.

Notes:  If you have two phone numbers programmed into your phone (see
        "Selecting the Active Phone Number" in Faxback Doc. # 46000),
        pressing RCL # -> displays the currently active phone number.

        Unless you selected the silent scratchpad function (see "Using
        Silent Scratchpad" in Faxback Doc. #45997), the other party on
        the line hears tones if you press these or any other keys on
        your phone during a call.

A Number Longer than Seven Digits

You can enter and dial phone numbers of up to 32 digits; however, the
phone can display only 7 digits at once.

To review the overflow digits of a number 8-10 digits long, press RCL
once.  Or, if the number is longer than 10 digits, press RCL twice.  The
phone displays the overflow digits (first to last), up to 7 digits at a
time.
