25 Channel Cordless Headset Phone
(430-1048)                 Care and Maintenance       Faxback Doc. # 39558


Your Radio Shack 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 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 Radio Shack 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 "Installation," Faxback Doc. # 39555, 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 through your local Radio Shack store.

Install the new battery pack as described below, then charge the battery
pack for about 15 hours before you use it the first time.

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 Radio Shack 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 curt-side collection, drop-off boxes at retailers such as
    your local Radio Shack 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 your 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 Radio Shack 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.
