Read This Before Installation

Each device that you connect to the phone line draws power from the phone
line.  We refer to this power draw as the device's ringer equivalence
number, or REN.  The REN is shown on the bottom of the base.

If you are using more than one phone or other device on the line, add up
all the RENs.  If the total is more than five, your phones might not ring.
In rural areas, a total REN of three might impair ringer operation.
If ringer operation is impaired, remove a device from the line.

FCC Statement

This telephone complies with Part 68 of FCC Rules.  You must, upon request, provide the FCC Registration Number and the REN to your phone company.  These numbers are shown on the bottom of the base.

Note:  You must not connect your phone to any of the following:

   coin-operated systems

Installing The Handset's Antenna

Insert the antenna into the hole at the top of the handset, then rotate
the antenna clockwise until it is secure.

Selecting a Location

You can place the phone on a desk top or table, or mount it on a wall.
Select a location that is:

   Near an AC outlet

   Near a telephone line jack

   Out of the way of normal activities

   Away from electrical machinery, electrical appliances, metal walls or
   filing cabinets, wireless intercoms, alarms, and room monitors

   Away from other cordless phones

The base's location affects the handset's range.  If you have a choice of
several locations, try each to see which provides the best performance.

CAUTION:  The supplied RadioShack adapter was designed specifically for
          your ET-551.  Use only the supplied adapter.

Notes:

   Your telephone connects directly to a modular telephone line jack.  If
   your phone line jack is not a modular jack, you can update the wiring
   yourself, using jacks and adapters available at your local RadioShack
   store.  Or, you can let the phone company update the wiring for you.

   The USOC number of the jack to be installed is RJ11C (RJ11W if you want
   to mount it on a wall plate).

Placing the Base on a Desk Top

Follow these steps when you place the base on a desk, shelf, or table.

1.  Plug on end of the supplied long modular cord into the LINE jack on 
    the back of the base.

2.  Insert the supplied power adapter's barrel plug into the DC 12V jack 
    on the back of the base.

3.  Route the adapter's cord through the strain relief slot on top of the
    base.

4.  Plug the adapter into a standard AC outlet.

5.  Plug the modular cord's other end into a modular phone line jack.

6.  Fully extend the base's antenna and place it in a vertical position.

Mounting the Base on a Wall Plate

1.  Plug one end of the supplied short modular cord into the LINE jack on
    the back of the base.

2.  Insert the supplied power adapter's barrel plug into the DC 12V jack on
    the back of the base.

3.  Route the modular cord through the groove on the bottom of the base and
    the adapter cord through the strain relief slot on top of the base.

4.  Plug the adapter into a standard AC outlet.

5.  Plug the short modular cord's other end into the wall plate jack, then
    align the base's keyhole slots with the wall plate studs and slide the
    base downward to secure it.

6.  Fully extend the base's antenna and place it in a vertical position.

Mounting the Base Directly on the Wall

For the mounting method, you need two wood screws (not supplied) with
heads that fit into the keyhole slots on the bottom of the base.

1.  Drill two holes 3 15/16 inches apart.  Then thread a screw into each
    hole, letting the heads extend about 5/16 inch from the wall.

2.  Plug one end of the supplied short modular cord into the LINE jack on
    the back of the base.

3.  Insert the supplied power adapter's barrel plug into the DC 12 V jack
    on the back of the base.

4.  Route the adapter's cord through the strain relief slot on top of the
    base.

5.  Align the keyhole slots with the mounting screws and slide the base
    downward to secure it.

6.  Plug the adapter into a standard AC outlet.

7.  Plug the cord's other end into a modular phone line jack.

8.  Fully extend the base's antenna and place it in a vertical position.

Connecting Charging The Battery Pack

The ET-551 comes with a rechargeable nickel-cadmium battery pack.  Before
using your phone, you must connect the battery pack then charge it for
about 24 hours.

Follow these steps to charge the battery pack.

1.  Press down and slide off the handset's battery compartment cover as
    shown.

2.  Insert the battery pack's connector into the phone's socket.  The plug
    fits only one way.

3.  Replace the cover.

4.  To charge the battery pack, simply place the handset on the base.

    The CHARGE indicator on the base lights.

Recharge the battery pack when the LOW BATT indicator on the handset flashes.

Notes:

   If the CHARGE indicator does not light when you place the handset on the
   base, be sure the battery pack and AC adapter are correctly and securely
   connected.

   When you first use the phone after charging or recharging the battery
   pack, the phone might not work and you might hear an error tone.  If 
   this happens, return the handset to the base for a few seconds.

   If the LOW BATT indicator does not light, but the phone does not work,
   recharge the battery pack.  The battery voltage might be too low to 
   light the indicator.

   If the battery pack gets weak during a call, the handset sounds three
   beeps every 30 seconds, and the LOW BATT indicator flashes for 2 min- 
   utes.  After 2 minutes, the phone automatically disconnects.  If this 
   happens, you cannot make another call on the phone until you recharge 
   the battery pack.

   About every 30 days, fully discharge the battery pack by keeping the
   handset off the base until the LOW BATT indicator lights.  Other wise,
   the battery pack loses its ability to fully recharge.

   Using a pencil eraser, clean the charging contacts on the handset and
   the base about once a month to make sure they are not dirty or tarnish- 
   ed.

   If the battery pack gets completely discharged, the ET-521 loses the
   security access-protection code.  To reset the code, place the handset
   on the base and charge the battery pack.

   The supplied battery pack should last about a year.  When the battery 
   pack loses its ability to fully recharge, order a replacement battery 
   pack from your local RadioShack store (see "Replacing the Battery
   Pack").

Setting The Dialing Mode

Set T/P (Tone/Pulse) on the back of the base for the type of service you
have.  If you are not sure which type you have, do this test.

1.  Set T/P to T.

2.  Lift the handset, press TALK, and listen for a dial tone.

3.  Press any number other than 0.

    Note:  If your phone system requires that you dial an access code (9,
           for example) before you dial an outside number, do not press
           the access code either.

    If the dial tone stops, you have a touch-tone service.  Leave T/P set
    to T.

    If the dial tone continues, you have pulse service.  Set T/P to P.

Turning The Ringer On Or Off

To turn off the ringer, set RINGER on the base to OFF.  To turn on the
ringer, set it to ON.

Note:  With the base's ringer off, you can still make calls using the
       phone.  You can also receive calls if you hear another telephone
       on the same line ringing.

Setting The Volume

Adjust VOLUME on the side of the handset to control the volume of the
sound you hear through the handset.
