Maintain Optimum Carry Phone Performance

When using the unit in your vehicle, secure the carry phone by running the
standard lap belt through the handle.

Do not carry the unit by the antenna or drop the unit directly on the
antenna.

Using the elastic loop provided, secure the antenna vertical, whether the
unit is carried or lying flat.

Checking Performance

Once the mobile telephone has been installed, its performance should be
checked using the following procedure.  Refer to Faxback Doc. # 46615 for
instructions on how to turn on, unlock, and place calls.

Step 1       Place a call from the mobile and confirm proper operation.
             Use both the handset and the optional hands-free during this
             call if the phone is so equipped.

Step 2       Have a call placed to the mobile and confirm proper operation
             Use both the handset and the optional hands-free during this
             call if the phone is so equipped.

Step 3       If you experience difficulty placing and receiving calls,
             check the voltage standing wave ratio (VSWR) using the
             following method.  Measure the power output of the radio with
             the radio connected to the vehicle antenna through a
             directional watt meter.  Measure the forward power and
             reflected power with the watt meter and compute the VSWR as
             follows:

             Voltage Standing Wave Ratio = 1+R/1-R Where R = (square root
             of [reflected power] divided by [forward power]).

             The VSWR should be less than 2:1.  If the VSWR is greater
             than 2, check the antenna and its cable connector.

Checking Auxiliary Alert Feature

Step 1       Prepare the unit to receive test calls by enabling the
             auxiliary alert feature.  Place a test call to the mobile.

Step 2       Verify the alert device has been activated by the incoming
             call and then answer the call.

Step 3       With the auxiliary alert feature enabled, place a second test
             call to the mobile.  Do not answer the call.  Verify that
             after approximately 20 seconds (5-6 rings), the alert device
             has been deactivated and that the handset displays CALL after
             being enabled.

Before Calling for Service

After installation, programming, and performance checkout, your cellular
telephone is ready for operation. If you experience operating difficulties
check the following before making a call for service.

Have you read your User Manual?

Everything you need to know to operate your cellular telephone is in your
User Manual.  Take the time to read it and become familiar with all the
features of your telephone before calling for service.  Note that not all
of the features discussed below are included in all telephone models.

If your telephone is equipped with digital hands-free, do you hear
excessive feedback noise during a hands-free call?

Because of audio variations in the cellular system, excessive feedback
noise or howling may sometimes be heard when a full duplex (if your
telephone is so equipped) hands-free call is placed or received.  If this
occurs, decrease the speaker volume using the volume control on the
handset.  Also, verify that the microphone was not installed in an area of
the vehicle that is subject to high background noise (above 85 dB SPL).
More information about hands-free operation can be found in your User
Manual.

Have you unlocked your unit?

Your cellular telephone is operative when locked.  This state is indicated
by loc'd in the display.  To unlock the telephone, enter your three-digit
unlock code.  Loc'd will disappear.

Does the red No SVC message continue to display?

This may indicate that you are outside of the service area, or in a
marginal reception area.  Marginal reception may also be indicated by the
fast busy or alternating high-low sound when attempting to place a call.

Have you programmed a unique operating mode into the unit?

Constant flashing of the Roam indicator or illumination of the No SVC
indicator while in your home service area may indicate an undesired roam
characteristic choice has been selected.  See 'Selectable system
Registration' or 'Roaming', in the User Manual.  [ ] or a message in the
display after the unit has been turned on also indicates that non-standard
settings have been programmed into the unit.
