ET-400 DUoFONE Cordless Telephone System
(430-0550B) Installation Faxback Doc. # 16896
INSTALLING THE BASE UNIT
The ET-400 is supplied with a telephone cable that has a modular plug at
each end. Route the cable through the convenient groove on the back of the
phone and connect one end to the modular jack on the bottom of the base
unit. Connect the other end to the phone lines at the standard modular
jack.
Connect the AC power cord to a source of AC power.
To install on the Wall
The ET-400 can be hung on a wall if desired. Use two screws with heads
that will fit into the key-hole slots on the back of the unit. Drill
suitable holes for inserting the screws. The two holes should be 3-15/16"
(100mm) apart. Thread the screws into the mounting surface, letting the
heads extend out from the wall about 5/32" (4mm). Route the cables into
the convenient groove and hang the ET-400 on the screws.
To Mount on Wall Plate
The spacing between the two holes is the same spacing as on a standard
modular wall phone plate If you use this phone plate, you can mount the
ET-400 directly on the plate. Use a shorter telephone cable (also
available at Radio Shack) instead of the one supplied.
To hang the Handset onto the Base Unit, first pull down the lever below the
switchhook on the Base Unit. This secures the Handset in place on the Base
Unit.
Installation Hints
- To avoid tripping over wires and damaging the unit, position the
base so that wires are not in the way of normal activities.
- Fully extend the Base Unit antenna.
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 at least 48 hours.
To charge the Handset battery pack, the Base Unit must be installed.
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 pack 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 you are not
talking on the ET-400. 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.
- You may leave the Handset turned on while it's charging on the Base
(after the initial 24-48 hour charge). To obtain maximum use of
batteries, turn the Handset off to charge every month or so. Note
however that the Handset is disconnected from the line: it won't
ring even if an outside call is received.
- When the Handset is constantly charging, whatever battery power is
used 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 of battery power, every month or
so charge the Handset completely, then take it off the charging unit.
Now battery power is usable until it's almost discharged. When the
BATT LOW indicator lights, recharge the batteries completely.
ENTERING THE SECURITY CODE
Understanding the Security Code
The exclusive programmable security code feature built into the ET-400 will
prevent unauthorized use of the phone line. Each time the TALK PUSH HANG-
UP is pressed, the personally selected security code is automatically
transmitted from the Handset to the Base Unit. The Base Unit compares the
code from the Handset with the 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 TALK PUSH HANG-UP is pressed.
To Enter the Code
1. With the Handset turned on, press the CODE ENTER button on the back of
the Base Unit. There will be a short tone from the Handset and its
TALK indicator will light.
2. Enter any four-digit number on the Handset keypad. (Use 0-9 buttons
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 the Base Unit is unplugged. 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 2-1/2
hours. If the code is lost, the error signal will be heard 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 bits of
conversation or from causing interference on the ET-400; this can
happen with any cordless telephone.
SETTING THE MODE (TONE/PULSE DIALING)
To determine the proper setting for the TONE/PULSE switch, first find out
if your phone line is a rotary or touch-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 buttons on the unit. If the dial tone continues, it is a
rotary type line; if it stops, it is a true touch-tone dialing line. If
rotary service is in place, set the switch on the Base to PULSE.
IMPORTANT: If a regular touch-tone system is familiar, don't be alarmed
when the same tone occurs each time a key is pressed even if
the switch on the Base Unit is set to TONE. they keytone on
the Handset is to assure that the key input is accepted. The
tones for dialing are generated in the Base Unit.
You can communicate with the tone access equipment (bank-by-phone,
alternate long distance service, etc.) even if the line is a rotary type.
After reaching the desired number (using the pulse dialing), press the LDT
key. The LDT indicator will light and your ET-400 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 to the pulse mode, but it is
actually not necessary because when you hang up, the ET-400 automatically
returns to pulse mode.
