(430-1048)                 Installation               Faxback Doc. # 39555


SELECTING A LOCATION

You can place the phone's base on a desk to, shelf, or table.
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,
    filing cabinets, wireless intercoms, security alarms, and room
    monitors.

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

Your telephone connects directly to a modular telephone line jack.
If your telephone wiring does not have a modular jack, you can update the
wiring yourself or have the telephone company update it for you.

    Notes:

    Radio Shack stores sell jacks and adapters to convert older wiring
    methods to modular wiring.

    The USOC number of the jack to be installed is RJK11C.

    Caution:

    The supplied adapter is a Class 2 120V AC/12V DC adapter that delivers
    at least 200 milliamps with its center tip set to positive.  Its plug
    correctly fits the phone's DC 12V jack.  Using an adapter that does
    not meet these requirements could damage the phone or the adapter.

CONNECTING THE PHONE

After you select a location for the phone's base, follow these steps to
connect it to AC power and to the phone line.

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

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

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

4.  Plug the adapter into a standard AC outlet.  The IN USE/CHARGE
    indicator lights when the keypad is on the base.

5.  Lift the base's antenna to a vertical position.

CONNECTING AND CHARGING THE BATTERY PACK

The ET-548 comes with a rechargeable nickel-cadmium battery pack in the
remote keypad.  You must connect and then charge the battery pack for at
least 15 hours before you use it the first time.

1.  Use a Phillips screwdriver to remove the screw that secures the
    battery compartment cover, then remove the cover.

2.  Slide the battery pack's connector onto the connector pins inside the
    battery compartment.

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

4.  To charge the battery pack, place the remote keypad on the base.
    The IN USE/CHARGE indicator on the base lights.

Recharge the battery pack when the TALK/LOW BATT. indicator lights.

    Notes:

    When you first use the phone after charging or recharging the battery
    pack, the phone might not work and you might hear error tones.
    (You do not hear the error tones if POWER is set to OFF.)

    If you hear the error tones, return the remote keypad to the cradle
    for at least 5 seconds to reset the security access-protection code.

    About once a month, fully discharge the battery pack by keeping the
    phone off the base until the TALK/LOW BATT. indicator lights.
    Otherwise, the battery pack loses its ability to fully recharge.

    If battery power is low, POWER is set to ON, and the headset is not in
    use, the TALK/LOW BATT. indicator slowly flashes.  If battery power is
    too low, the indicator does not light.

    If the IN USE/CHARGE indicator does not light when you place the
    remote keypad on the base, be sure the battery pack and AC adapter are
    correctly and securely connected.  Also, check the charging contacts
    on the remote keypad and base.  If the contacts are dirty or
    tarnished, clean them with a pencil eraser.

ATTACHING THE HEADSET HOLDER

Put the headset holder into the slot on the back of the base and slide it
into place.

ADJUSTING THE HEADSET

1.  Put on the headset, and adjust the band until it rests with almost no
    pressure on your ear and the top of your head.

    If the headset is loose, remove it and gently push the headset band
    inward slightly to tighten it.  If the headset is tight, gently pull
    the headset band out to loosen it.

2.  Hold the headset in place, and turn the microphone boom until it is
    about 2 inches from your mouth.

    When you are not using the headset, place it on the headset holder.

SETTING THE DIALING MODE

Set TONE-PULSE on the side of the base for the type of service you have.
If you are not sure which type you have, do this simply test after
charging the battery.

1.  Set POWER to ON.

2.  Set TONE-PULSE to TONE.

3.  Lift the remote keypad from the base.
    Then press TALK/HANG UP and listen for a dial tone.

4.  Press any number other than 0.

    If the dial tone stops, you have touch-tone service.
    Leave TONE-PULSE set to TONE.

    If the dial tone continues, you have pulse service.
    Set TONE-PULSE to PULSE.

USING THE BELT CLIP

Use the belt clip to hang the remote keypad on your belt or waistband for
handsfree carrying.
