ET-548 25-Channel Cordless Headset Telephone
(430-1048A)                Care and Maintenance       Faxback Doc. # 51345

Your RadioShack ET-548 25-Channel Cordless Headset Telephone is an example
of superior design and craftsmanship.  The following suggestions will help
you care for your phone so you can enjoy it for years.

  Keep the phone dry.  If it gets wet, wipe it dry immediately.  Liquids
  might contain minerals that can corrode the electronic circuits.

  Use and store the phone only in normal temperature environments.
  Temperature extremes can shorten the life of electronic devices, damage
  batteries, and distort or melt plastic parts.

  Handle the phone gently and carefully.  Dropping it can damage circuit
  boards and cases and can cause the phone to work improperly.

  Keep the phone away from dust and dirt, which can cause premature wear
  of parts.

  Wipe the phone with a damp cloth occasionally to keep it looking new.
  Do not use harsh chemicals, cleaning solvents, or strong detergents to
  clean your phone.

Modifying or tampering with the phone's internal components can cause a
malfunction and might invalidate its warranty and void your FCC
authorization to operate it.  If your phone is not performing as it
should, take it to your local RadioShack store for assistance.  If the
trouble is harming the phone lines, the telephone company might ask you to
disconnect your phone until you have resolved the problem.

Replacing The Battery Pack

If you follow the instructions in "Connecting and Charging the Battery
Pack" in Faxback Doc. # 51342, the battery pack should last about a year.
If the battery pack does not hold a charge for more than 2 hours after an
overnight charge, replace the battery pack with a new 3.6 volt, 300
milliamp battery pack with a connector that fits the connector pins in the
battery pack compartment.  You can order a replacement battery pack (RSU
10450971) through your local RadioShack store.

Install the new battery pack as described below, then charge the battery
pack for about 15 hours before you use if the first time (see "Connecting
and Charging the Battery Pack" in Faxback Doc. # 51342.)

1.  Use a Phillips screwdriver to remove the screw on the battery
    compartment cover on the remote keypad, then remove the cover.

2.  Gently pull on the battery connector to disconnect it, then remove the
    battery pack.

3.  Slide the battery pack's connector onto the connector pins inside the
    battery compartment and put the battery pack into the compartment.

4.  Replace the cover and secure it with the screw.

CAUTIONS:  You must use a replacement battery pack of the required size
           and type.

           Be careful not to short the battery pack by touching it with
           conducting materials, such as rings, bracelets, and keys.  The
           battery pack or conductor might overheat and burn.

           Do not dispose of the battery pack in a fire because it might
           explode.

           Do not open or mutilate the battery pack.

Notes:  If you have trouble replacing the battery pack, take the phone to
        your local RadioShack store for assistance.

        To avoid losing numbers stored in memory, try to install and begin
        charging the new battery pack within 2 minutes of removing the old
        one.

IMPORTANT:  Your telephone contains a rechargeable nickel cadmium battery
            pack.  At the end of the battery pack's useful life, it must
            be recycled or disposed of properly.  Contact your local,
            county, or state hazardous waste management authorities for
            information on recycling or disposal programs in your area.
            Some options that might be available are: municipal curb-side
            collection, drop-off boxes at retailers such as your local
            RadioShack store, recycling collection centers, and mail-back
            programs.

The FCC Wants You to Know

In the unlikely event that your phone causes problems on the phone line,
the phone company can temporarily discontinue your service.  If this
happens, the phone company attempts to notify you in advance.  If advance
notice is not practical, the phone company notifies you as soon as
possible and advises you of your right to file a complaint with the FCC.

Also, the phone company can make changes to its lines, equipment,
operations, or procedures that could affect the operation of this
telephone.  The telephone company notifies you of these changes in
advance, so you can take the necessary steps to prevent interruption of
your telephone service.

your phone might cause TV or radio interference even when it is operating
properly.  To determine whether you phone is causing the interference,
turn off your phone.  If the interference goes away, your phone is causing
the interference.  Try to eliminate the interference by:

  Moving your phone away from the receiver.

  Connecting your phone to an AC outlet that is on a different electrical
  circuit from the receiver.

  Contacting your local RadioShack store for help.

Lightning

Your telephone has built-in lightning protection to reduce the risk of
damage from surges in telephone line and power line current.  This
lightning protection meets or exceeds FCC requirements.  However,
lightning striking the telephone or power lines can damage your telephone.

Lightning damage is not common.  Nevertheless, if you live in an area that
has severe electrical storms, we suggest that you unplug your phone during
storms to reduce the possibility of damage.
