NEC DB4000 User manual

General safety
lObserve ‘Turn off 2-way radio’ signs, such as those near stores of fuel, chemicals or explosives.
lDo not allow children to play with the phone, charger or batteries.
lA small rubber bung (for antenna socket protection) is included in the carton. Keep this out of reach of small children, for whom it could be hazard.
lThe operation of some medical electronic devices, such as hearing aids and pacemakers, may be affected if a cellphone is used next to them. Observe any warning signs and
manufacturer’s recommendations.
Road safety
lYou MUST exercise proper control of your vehicle at all times.
lThe handset or hand-held microphone should not be used while driving. Find a safe place to stop first or use the hands-free kit available.
lDo not speak into a hands-free microphone if it will take your mind off the road.
lYou MUST NOT stop on the hard shoulder of a motorway to answer or make a call, except in an emergency.
lSwitch off your cellphone at a refuelling point, such as a petrol station, even if you are not refuelling your own car.
lDo not store or carry flammable or explosive materials in the same compartment as a radio transmitter, such as a cellphone.
lYou must not use the phone’s car kit alert device to operate the lights or horn of your vehicle while on a public road.
lElectronic vehicle systems, such as anti-lock brakes, speed control and fuel injection systems are not normally affected by radio transmissions. The manufacturer of such equipment can
advise if it is adequately shielded from radio transmissions. If you suspect vehicle problems caused by radio transmissions consult your dealer and do not switch on your phone until it has
been checked by qualified approved installers.
Third party equipment
The use of third party equipment, cables or accessories, not made or authorised by NEC, may invalidate the warranty of your cellphone and also adversely affect the phone’s operation. For
example use only the NEC mains cable supplied with the AC charger.
Service
The cellphone, batteries and charger contain no user-serviceable parts. We recommend that your NEC cellphone is serviced or repaired by an NEC authorised service centre. Please contact
your Service Provider or NEC for advice.
Non-Ionising Radiations
The radio equipment shall be connected to the antenna via a non-radiating cable (e.g. coax).
The antenna shall be mounted in a position such that no part of the human body will normally rest close to any part of the antenna unless there is an intervening metallic screen, for example,
the metallic roof.

Before you start
Cellphone system structure
It is worth remembering that every time you use your phone, three different organisations are involved:
All the features described in this user guide are supported by your phone . However, for all these features to work, you must have a SIM card (supplied by your Service Provider) that also
supports these features. Even if you have a fully featured SIM card, any feature not supported by the Network transmitting your call will not work. This last point is especially important when you
are roaming networks (see page 10).
User guide conventions
The following markers are used throughout the user guide to attract your attention:

Getting Started
This cellphone is a dual band digital type designed for use on a Global System for Mobile Communications (GSM) network. GSM networks
are installed and planned for many countries throughout Europe and operate on two frequencies: 900MHz (known as GSM900 or just GSM)
and 1800MHz (known as GSM1800 or PCN - Personal Communications Network). Your cellphone is capable of working on both of these
systems.
This world standard allows you to roam and use your own phone in other countries. You can, if you wish, make and receive all calls as if you
were in your home country, with all billing being made via your normal Service Provider.
Preparing the phone
Before you try to use your phone check the following has been carried out.
lValid SIM card inserted (see below)
lBattery charged (see page 13)
lPIN 1 code entered (if necessary - see page 2)
SIM card
Before using your cellphone you must sign-up with one of the digital network Service Providers. In addition to your subscription details you
will receive a personal SIM (Subscriber Identity Module) which is inserted into your phone.
If the SIM card is removed then the phone becomes unusable until a valid SIM is fitted. It is possible to transfer your SIM to another
compatible phone and resume your network subscription.
There are two types of SIM, plug-in and full-size, and this phone uses the plug-in type. The screen on your phone will display appropriate
messages if no SIM is fitted.
Inserting a SIM
lMake sure that the power is off and then remove the battery À&
Áto reveal the SIM location.
lSlide the catch Âin the direction of the open arrow.
lInsert the SIM Ã, ensuring the gold contacts are face down and
the notch on the card lines up with the SIM location recess.
lSlide the catch in the direction of the lock arrow and replace the
battery.
OThe phone supports a number of
languages and the keyboard symbols have
been chosen for world-wide operation.
OThe digital technology of your NEC GSM
phone helps to ensure that your
conversations are kept secure.
OIf the phone, or the SIM, is lost or stolen
then you should contact your Service
Provider immediately in order to bar it
from use.
OThe SIM card contains personal data such
as your electronic phonebook, messages
(see page 50) and also details of the
network services you have subscribed to.
The phone will not work (except for
emergency calls on some networks)
unless a valid SIM is fitted.
OIf the SIM is already fitted, see Start-up on
page 2.
OIf you insert a SIM card other than your
own, information such as call logs may be
lost.

PIN 1 code
The SIM card issued by your service provider has a security feature called PIN 1 code protection. The PIN 1(Personal Identification Number)
is a number put onto the card by your Service Provider, and is 4 to 8 digits long. Some service providers supply SIM cards which will cause
your phone to prompt for a PIN 1 code when it is turned on. If this is the case, use the phone’s keypad to enter your code. You can disable
this prompt (see page 41).

Connecting to the network
*Hold down the power key for about a second, to switch on.
After start-up, and correct PIN 1 code entry if necessary, the phone searches for a network. When found, the network name and country are
displayed. You also see the time, signal strength, battery strength and any area messages if this facility is enabled (see page 57).
The phone’s LCD display shows the strength of the radio signal that links your phone to the network. A maximum signal is shown by 5 shaded
blocks and a minimum signal by 1 block.
Receiving calls
When someone calls your number, the phone’s ringer will sound, if set (see page 19), and the incoming call screen is displayed (see right).
The phone number of the person calling may be displayed in the middle of the screen if the calling line identification (CLI) facility is available
and the caller has activated the feature. If the caller’s phone number has been stored in your phonebook along with a name (see page 30), that
name will be displayed. If the caller has withheld their identity then the screen will give a message that the incoming number is being
withheld.
Accepting a call
*Press the key or open the Flip (if the Flip option is active - see page 3).
Rejecting a call
*Press briefly or close the Flip (if the Flip was already open and the Flip option is active - see page 3).
You also have options for holding calls and diverting calls. These options depend upon your network and your subscription arrangements.
If your cellphone receives a call and you do not answer it, the screen will display the telephone number (or the name if a stored number) of
the caller (if available). This information is stored in the unanswered calls list. Up to 10 unanswered calls are stored in this list. The last 10
answered calls are stored in the answered calls list.
OIf the screen indicates Searching or
No Service you will not be able to
make or receive any normal calls. You may
be able to make emergency calls.
OYou can set your phone to answer a call
when any key except the key is
pressed - see 'Answer key' on page 20. If
you are making a call, the phone gives
priority to receiving a call unless you have
already pressed the key.
