Getting Started

    Make sure the battery is properly installed.

Battery Charge Indication

The vertical bar to the right of the B on the right side of the phone dis-
play shows the battery charge level.  The higher the bar, the more power
left in the battery.

STOP  To Achieve Full Battery Capacity, New Batteries Must Be Charged With
      The Phone Off For at Least 24 Hours Before Initial Use.

Charging a Battery

1.  Install the battery and connect the charger to the base of the phone.

2.  Connect the charger to a standard AC wall outlet.  Segments of the
    battery indicator bar on the right-hand side of the display will start
    scrolling and the charger connected tone is simultaneously emitted.

    You can use the phone during the charging, but the charging will be
    reduced for the duration of the call.

3.  After the segments of the battery indicator bar stop scrolling and the
    bar is entirely displayed, the battery is fully charged.

4.  Disconnect the charger from the power outlet and phone.

    Battery charging times depend on the type of battery and charger used.
    Battery operation times depend greatly on how you use the batteries, as
    well as, on the coverage of the network and network parameters set by
    the cellular service provider.

    If the battery is too hot or cold, the charging may be interrupted
    until the battery reaches its normal operating temperature.

Signal Strength Indication

A cellular phone sends and receives radio signals. As with all radio equip-
ment, the quality of radio reception depends on the strength of the radio
signal in the area where you are operating your phone.

The strength of the cellular signal is shown by the vertical bar to the
left of the S indicator on the left-hand side of the display.  The higher
the bar, the stronger the signal is at the location where you are operating
your phone.

  Where the NO SVC indicator is displayed the phone is outside the cellular
  service area and calls can not be made or received.

  If the signal is poor and you are using the phone in a building, it may
  be beneficial to move near a window for better reception.
