ET-410 DUoFONE Cordless Electronic Telephone System
(430-0551)                 Installation               Faxback Doc. # 17582

INSTALLING THE BASE UNIT

The ET-410 comes with a modular plug installed on the end of its telephone
cable.  Connect it directly to the phone lines through a standard modular
jack (used throughout the USA).

1.  Disconnect the regular telephone from the wall jack and connect the
    ET-410 modular plug in its place.

2.  Connect the AC power cord to a standard AC outlet.

3.  If the ET-410's intercom feature will be used, plug a regular telephone
    into the modular jack on the back of the ET-410 Base Unit.  A telephone
    connected here may be used normally or as an intercom with the ET-410
    Handset.

WARNING:  This unit must be grounded for proper lightning protection.

Installation Hints

    To avoid tripping over wires and damaging the unit, position the 
    Base so that the wires are not in the way of normal activities.

    Fully extend the Base Unit antenna.

    Check to see that the POWER indicator is on.

CHARGING THE HANDSET

The Handset has a built-in rechargeable battery pack.  As supplied, this
battery pack is usually fully discharged.  Before use, the Handset battery
pack should be charged for 24 -48 hours.

To charge the Handset battery pack, the Base Unit must be installed as
described above.

Charging on Base Unit

1.  Be sure the POWER switch on the Handset is off.

2.  Place the Handset in its cradle on the Base Unit.

3.  The red charging indicator will light on the Handset when the
    Handset is charging properly.

NOTE:  Charging will be hindered if the charging contacts become dirty or
       tarnished; clean them occasionally with a pencil eraser.

Charging Hints

    Once the battery back has been fully charged, recharge the Handset
    about two hours for every one hour it is used.

    The Handset uses a small amount of power, even when no one is talking
    on the ET-410.  A full charge will last 24 hours with the POWER switch
    set to ON; the charge will last several days with the switch in the OFF
    position.  It is best to have the Handset on charge, whenever possible.

    The charging rate is automatically reduced as the batteries approach a
    full charge.  They will not be harmed by leaving the Handset on charge.

    It is acceptable to leave the Handset turned on while it's charging
    on the Base (after the initial 24 - 48 hour charge).  However, to
    obtain maximum use of batteries, turn the Handset off to charge every
    month or so.  Note however the Handset is disconnected from the line: 
    it won't ring even if an outside call is received.  (The regular
    telephone connected to the ET-410 will ring.)

    When the Handset is constantly charging, when battery power is used it
    is continually replenished.  Because only a small amount of battery
    power is used, the unit loses the capability to use the rest of its
    power.  To get the most use out of batter power, every month or so
    charge the Handset completely, than take it off the charging unit.  Now
    use battery power alone unit it's almost discharged.  Before all power
    is used, recharge the batteries completely.

SETTING THE MODE (Tone/Pulse Dialing)

To determine the proper setting for the TONE/PULSE switch, find out if the
phone line is a rotary or tone dialing type.  To do this, connect the
phone, set the switch to TONE, lift the Handset from the Base Unit or press
the TALK PUSH HANG-UP button (to get a dial tone), and press any of the
number keys on the unit.  If the dial tone continues, the line is a rotary
type; if it stops, it is a true tone dialing line.  If the line is rotary
service, set the switch on the Base to PULSE.

IMPORTANT:  If a regular tone dialing phone system is familiar, don't be
            alarmed when the same tone sounds every time a key is pressed
            even if the switch on the Base Unit is set to TONE.  The
            keytone on the Handset is there to assure that the key input is
            accepted.  The tones for dialing are generated in the Base
            Unit.

It is possible to communicate with the tone access equipment (bank-by-
phone, alternate long distance service, etc.) even if the phone line is a
rotary pulse type.  After reaching the desired number (using the pulse
dialing), press the LDT key.  The LDT indicator will light and the ET-410
is temporarily put into tone mode.  Then key in the desired information
such as a personal ID (billing) code number, area code and number, etc.

Pressing the LDT key again will return the unit to pulse mode, but it is
actually not necessary because hanging up automatically returns the ET-410
to pulse mode.

ENTERING THE SECURITY CODE

Understanding the Security Code

The exclusive programmable security code feature built into the ET-410 will
prevent unauthorized use of the phone line.  Each time the TALK PUSH HANG-
UP button is pressed, a personally selected security code is automatically
transmitted from the Handset to the Base Unit.  The Basue Unit compares the
code from the Handset with its security code.  If the two codes are the
same, the call may proceed; if they are not the same, the Handset will
sound an error signal and the TALK indicator will go off.  Once the
security code is entered, the above "verification" procedure takes place
automatically each time the TALK PUSH HANG-UP button is pressed.

To Enter the Code

1.  With Handset POWER turned on, press the CODE ENTER button on the 
    back of the Base Unit.  The Handset will give a short tone and its
    TALK indicator will light.

2.  Enter any four-digit number on the Handset keypad.  (Use the 0 - 9
    keys only.)  The TALK indicator will go off and another short tone
    will sound.

The security code has now been entered in the Handset and the Base Unit.

Security Code Hints

    A memory protection circuit in the Base Unit holds the memory for 2-1/2
    hours after unplugging the Base Unit.  The security code will be lost,
    and must be re-entered, if the Handset battery pack discharges
    completely or if the Base Unit is unplugged for over 2 hours.  If the
    code is lost, there will be an error signal when TALK PUSH HANG-UP is
    pressed.

    The security code prevents other cordless telephones from initiating or
    answering a call on the phone line.  It does not prevent other radio
    units on the same frequency from inadvertently hearing a conversation
    or causing interference on the ET-410; this can happen with any
    cordless telephone.
