INSTALLING THE BATTERY

To install the battery, place it flat against the back of the phone with
the tab facing up and toward the top of the phone.  Then slide the battery
toward the top of the phone until it snaps into place.

To remove the battery, be sure the phone is turned off, then hold down the
tab, slide the battery down and lift it off the phone.

Important Battery Tips

   You must fully charge a new battery at least 24 hours before you first
   use it.  See "Charging the Battery" below.

   Use only the supplied charger and use only batteries recommended for
   this phone.

   A new battery's full performance is achieved only after two or three
   complete charge and discharge cycles.

   When you are not using the charger, disconnect it from power.  Do not
   leave the charger connected for more than a week, since overcharging
   could shorten the battery's life.

   If left unused, a fully charged battery discharges itself in about a
   week.

   When the battery is not in use, store it uncharged in a cool and dark
   place.

   The battery is a sealed unit with no serviceable parts.  Do not try to
   open the case.

   You can purchase additional standard or extended capacity batteries
   through your local RadioShack store.

   A battery can be charged and discharged hundreds of times, but it
   eventually wears out.  When the operating time (talk time and standby
   time) is noticeably shorter then normal, it is time to get a new
   battery.

   Leaving the battery in a hot or cold place, such as in a closed car in
   the summer or winter, reduces the battery's capacity and life.  Always
   try to keep the battery between 59 and 77 degrees F (15 and 25 degrees
   C).  A phone with a battery that is too hot or too cold might not work,
   even when the battery is fully charged, until the battery returns to a
   normal temperature.  Nickel metal hydride (NiMH) batteries are
   particularly limited in temperatures below 14 degrees F (-10 degrees
   C).

   Use the battery only for its intended purpose.

   Never use any charger or battery that is damaged or worn out.

   Do not short-circuit the battery.  Accidental short-circuiting can
   occur when a metal object (coin, paper clip, pen or similar item)
   directly connects the battery's + and - terminals (the metal stripe on
   the back of the battery), such as when you carry a spare battery in
   your pocket or purse.  Short-circuiting the terminals might damage the
   battery or the object connected to it.

   Do not dispose of batteries in a fire!

     Nickel-Cadmium and Nickel-Metal Hydride batteries must be recycled or
     disposed of properly. They must not be disposed of in municipal
     waste.

CHARGING THE BATTERY

Once you install the battery on the phone, follow these steps to charge
the battery using the supplied charger.

1.  Insert the charger's barrel plug into the jack on the bottom of the
    phone.

2.  Connect the charger's AC plug to a standard AC outlet.  The phone
    beeps and its battery charge bar appears and begins to scroll.

    Notes: You can use your phone during charging, but charging takes
           longer.

           For the fastest charging, be sure the phone is turned off, if
           you are not expecting a call.

           If the battery is too hot or cold, charging stops until the
           battery temperature returns to normal.

3.  The battery charge bar stops scrolling when the battery is fully
    charged.  Disconnect the charger from the AC outlet first, then
    disconnect it from the phone.

Using the supplied battery (fully charged), you have about 1 hour, 40
minutes of talk time or 21 hours of standby time.

WHEN TO RECHARGE THE BATTERY

Your phone displays the battery charge bar whenever the phone is on to
keep you informed about the battery's power level.  The higher the bar,
the more power left in the battery.

You can recharge the battery (as described in "Charging the Battery"
above) at any time.  However, when your phone gives you these low-battery
indications, recharge the battery as soon as possible."

   When only a few minutes of talk time remain, the phone sounds a warning
   tone and displays BATTERY LOW at regular intervals.

   When the battery charge level is too low for the phone to operate, the
   phone displays RECHARGE BATTERY and sounds a warning tone.  The phone
   automatically turns off about 10 seconds later.

Note:  The phone does not sound low battery warning tones if silent
       service is set to ON (see "Ring Type" in Faxback Doc. # 46086).

DISCHARGING BATTERIES

Rechargeable batteries last longer and perform better if occasionally
allowed to fully discharge.  You can do this by leaving the phone on until
the phone automatically turns off or you can use the battery discharge
feature of any approved accessory available for your phone.

Do not try to discharge the battery by any other means.
