Motorola StarTac-6000 Wearable Cellular Telephone
(170-1234/35/36/37)        Troubleshooting            Faxback Doc. # 51445

Q.  I pressed the power button, but nothing happened.  What's wrong with
    my phone?

A.  Check that you have installed a battery and that the battery is
    charged.  See Faxback Doc. # 51437 for more information about
    batteries for the StarTAC phone.

Q.  My battery didn't last as long as I expected.  What can I do to extend
    battery life?

A.  Keep in mind that your battery's "talk-time" and "standby-time" are a
    relative measurement of the battery's capacity.  The more you talk on
    the phone, the less stand-by time you will have and vice versa.

    To get the most from your battery, make sue it is fully charged.  To
    charge the battery to 100% of its capacity, leave it in the charger
    for an extra hour after the charger's light turns green.

    Certain features can demand power from your battery and reduce battery
    life.  If you have selected the Automatic Display of Individual Call
    Timer feature, the display uses battery power to remain active during
    each call.  Turn this feature OFF to conserve battery energy.  (See
    Faxback Doc. # 51440 for more information on this feature.)

    Exposing your battery to extreme temperatures - below -10 degrees C
    (14 degrees F) or above 45 degrees C (113 degrees F) - can shorten
    battery life.  Batteries are especially sensitive to high temperature
    extremes.  As a good rule of thumb, always take your phone with you
    when you leave your car.

Q.  The display says, "Locked."  How do I unlock my phone?

A.  Try entering the last three digits of your cellular number.  If that
    doesn't work, try using the factory preset lock code: 123.  If all
    else fails, call your cellular service provider (the company that
    sends you your monthly cellular bill) for assistance.  (See Faxback
    Doc. # 51441 for more information on your phone's Security Features.)

Q.  I tried to place a call and received a fast busy signal.

A.  This sound means that the cellular system did not process your call.
    For example, the cellular system may be overloaded with call attempts.
    To redial the number, press [SND] before ending your call attempt, or
    press [END] and try to call again later.  (See Faxback Doc. # 51438
    for more information of redialing.)

Q.  I tried to place a call and received an alternating high/low tone.

A.  This sound means your call did not reach the cellular system.  Most
    likely, you dialed the number too soon after turning the phone ON.
    Wait until the red NS light stops blinking before placing a call.

    An alternating tone may also indicate that your phone's signal is
    blocked.  Make sure the antenna is fully extended and move clear of
    any obstructions, like bridges, parking garages, tall buildings, etc.

Q.  My phone started beeping and the display says: "Call 01."  What
    happened?

A.  This sound means that someone tried to call you while you were in an
    area where the cellular signal was weak.  Press [CLR] to clear your
    display, extend your phone's antenna and avoid obstructions like
    tunnels, parking garages and tall buildings whenever possible.

Q.  I am in my home service area but the Roam Indicator is flashing.

A.  If your phone is programmed with more than one telephone number, you
    might not have switched to the number appropriate for your current
    location.  Press [RCL], [# >], [STO] to switch to your other number.
    (See Faxback Doc. # 51442 for more information on multiple phone
    numbers.)

Q.  I tried to read my Voice Mail (or use a paging service, a calling
    card, etc.) but nothing happened.

A.  You have probably turned OFF the Scratchpad tones.  Place your call,
    enter the access numbers when prompted by the recording, then press
    [RCL], [SND].  To avoid this problem in the future, follow the
    directions in Faxback Doc. # 51440 to turn the Scratchpad tones ON.

Q.  I tried to place a calling card call using the internal Phone Book,
    but it didn't work.

A.  You may have turned OFF your Scratchpad tones.  Follow the directions
    in Faxback Doc. # 51440 to turn the Scratchpad tones ON.

    Check that you stored your calling card information in the correct
    order, and make sure the groups of numbers are separated by pauses.
    The easiest way to correct the sequence may be to start from scratch.
    Follow the instructions in Faxback Doc. # 51439, enter your calling
    card information again and store it in the same memory location as
    your previous attempt.

    Also keep in mind that when using your calling card, you must enter
    the number you are calling with the area code, but without the initial
    "1."  Check with your long distance carrier for details on using your
    calling card.

Q.  My phone was stolen.  What should I report and to whom?

A.  Report a stolen phone to the police and to your cellular service
    provider (the company that sends you your monthly cellular service
    bills).
