INTRODUCTION
GLOSSARY
OF TERMS
Base set number
The base set number is the local number assigned to
the base set for registration of a service. A handset of
this base set can have another number assigned to it.
Engaged handset
Somebody is using the handset.
Free handset
A registered handset ready to receive calls.
Handset number
A number by which the base set identifies a handset.
The current number of the hand set depends on the
current registration.
Key
Is a button on the telephone’s keypad.
Registration
The service registration is a prerequisite which must be
met before a handset can use the services of the base
set. Note that a handset can register with several base
sets.
Icon
Denotes a symbol with information on the operating
state of the device.
Tone
Denotes a tone generated by the receiver or loudspeaker
of the handset.

6
INTRODUCTION
The base set maintains radio contact with the handset.
Radio contact can be maintained over 300 m distance
outdoors and up to 50 m inside a building. The radio
reception can be impaired by obstacles in the path of the
radio signals. The quality of the voice communication
deteriorates rapidly at the fringe of and outside the range
of the base set and handset. A beep warns you that you
are leaving the reception range. If you hear the beep,
move nearer the base set, otherwise the communication
will be interrupted after about 10 seconds.
If the handset makes the radio link with the base set, you
hear the reception tone.
The best radio communication exists if you can see the
base set while using the handset.
The functions of your telephone are programmed via the
telephone buttons. If during a programming procedure
the telephone detects no activity within 20 seconds, i.e.
if no button is pressed within this time, the programming
is cleared and you must start the programming again.
Many functions of your telephone have default settings
when you buy it. You can change these defaults (see the
chapter on settings, page 25 and following).
The handset PIN protects the settings of the handset. If
you want to change the settings you must enter the
handset PIN as part of a programming procedure.
The default PIN of the handset is ”1590”. You can chan-
ge this number at any time (see pages 36-37).

CONNECTION / START-UP
Before you connect and use your cordless phone, load
the three supplied NiMh batteries in the handset. If link
and stand-by hours are out of specification despite
correct charging, you must replace the batteries. Make
sure that you buy quality batteries such as are available
from a specialized dealer. Poor quality batteries can
effect the voice quality of your telephone.
• Open the battery compartment on the rear of your
handset by pulling the battery compartment cover.
• Take out the old batteries.
• Load the new batteries making sure to install the poles
correctly (see diagram in battery compartment).
• Replace the cover on the battery compartment.

THE BATTERIES

To charge the batteries, place the handset in the base set.
Before using the handset for the first time, charge the
batteries for 24 hours. Low battery voltage is indicated by
the battery icon on the LCD of the handset.

BATTERY DISPOSAL
Important note:
The battery charge LED on the base set should light when
you place the handset in the base set. If the LED does not
light either the handset is not placed correctly in the base
set or the battery charge is not working.
The batteries cannot reach their full capacity at the first
charge. Physical reasons prevent this. Therefore the time
until depletion of the batteries can be shorter than nor-
mal; this will balance out after several charges.
The charge capacity of the batteries deteriorates with age
and due to the memory effect* which prevents full char-
ge. Generally, the handset should be completely dischar-
ged and recharged from time to time. The discharge state
of the battery is indicated by the battery charge icon
and / or a warning beep.
To ensure that the batteries are charged correctly, clean
the charging contacts once a month with a soft cloth.
*) Repeated partial charging and discharging shifts the
capacity point of the batteries and less capacity is left.
Each partial charge or discharge defines a new capacity
point and shortens the life of the batteries.
Spent batteries must not be disposed of with the house-
hold garbage. Return spent batteries for recycling to your
dealer or a battery collection center. Because of the risk
of explosion, batteries must not be thrown in the fire. To
avoid fire and explosion, charge the batteries only with
the base set.

BASE SET
Observe the following points for setting up the base set:
• Place the base set on a level surface (e.g., a table).
• If you want to use several handsets with the base set,
ensure that the base set is about the same distance
from each handset.
• To avoid interference, maintain a minimum distance of
50 cm between the handset and other electronic equip-
ment (e. g., a fax machine, television set, monitor
screen, etc.).
• Place the base set near a mains socket.
