Using The Battery

WARNING:  A detached battery could cause property damage, injury, or burns
          if a metal object (such as a pen spring, beaded chain, or piece
          of jewelry) contacts the battery' terminals and causes a short
          circuit.  Be careful when placing a charged battery inside a
          coat pocket, purse, or other container that might contain metal
          objects.

CAUTION:  Batteries must be recycled or disposed of properly.  (You can
          put them in the battery recycling box at your local RadioShack
          store.)  They must not be disposed of in municipal waste.

Installing The Battery

1.  Place the battery flat against the back of the phone and align the top
    of the battery below the raised arrows.

2.  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 press the 
latch at the top of the battery and slide the battery toward the bottom of 
the phone until is stops.  Then lift the battery off the phone.

Note:  If you have an extra charged battery and the currently installed
       battery becomes low during a call, you can change the battery
       without ending the call or losing the connection.  See "Replacing a
       Battery During a Call", below.

Charging The Battery

The nickel metal hydride battery supplied with your telephone is shipped 
in a discharged state to extend the battery's life.  It must be fully 
charged before you can use your phone.

We recommend that you charge a new battery overnight, but no longer than 
24 hours, using the AC charger supplied with your phone.  Recharging time 
varies based on the type of battery and the amount of charge left in the 
battery.  See "Recommended Recharging Times", below.

Follow these steps toe charge the supplied (or any approved) battery using 
the charger supplied with your phone.

1.  Install the battery on the phone.

2.  Remove the charging jack cover on the bottom of the phone and insert
    the charger's flat plug into the charging jack.

    Note:  The plug fits into the jack only one way.  If you have
           difficulty inserting the plug, turn it over and try again.  Do
           not force it.

3.  Plug the charger's power cord into a standard AC outlet.  The battery
    charge indicator appears.

 Notes:  You can use the phone while it is charging, but charging takes
         longer.

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

4.  When the battery is fully charged, disconnect the charger from the AC
    outlet.  Then press in the clips on the sides of the plug and pull it
    away from the phone to disconnect the charger.  Replace the charging
    jack cover.

    NiMH High Capacity (supplied)      5-1/4
    NiCd Extra Capacity                5-1/2

Checking Battery Power

The phone displays a graduated set of up to three battery level indicators 
(short, medium and long battery symbols) when it is turned on.  The more 
indicators that appear, the higher the battery's current charge level.

To see a more detailed indication of the battery's charge level at any 
time, press [FCN] [4 GHI].  The battery strength meter appears on the 
display for about 5 seconds.  Read this meter in the same way.

When battery power becomes low, the phone displays Lo bAt and sounds a 
warning tone every few seconds.  When power becomes too low for the phone 
to operate, it automatically turns off.  Recharge the battery as soon as 
possible.

Note:  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.

Replacing A Battery During A Call

If you have an extra charged battery and the currently installed battery 
becomes low during a call, follow these steps to change the battery 
without ending the call or losing the connection.

1.  Tell the other party on the line what you plan to do (tell them, for
    example, that they will hear some noise as you remove the battery and
    you will call back if for any reason you lose the connection).

2.  Remove the battery, and within 3 seconds, install the fresh battery.
    Your call is still on the line.

    Note:  If you do not complete Step 2 within 3 seconds, the call
           disconnects.

Important Battery Tips

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

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

  When you are not using the charger, disconnect it from power.  Do not
  leave the battery connected to the charger and AC power for more than 24
  hours, since overcharging could shorten the battery's life.

  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.

  For the best results, be sure the battery is at or near room temperature
  when you charge it.

  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 than normal, get a new battery and recycle
  or properly dispose of the old one.

  Do not dispose of batteries in a fire.

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