Switch off your phone before boarding an aircraft. The
use of wireless telephones in an aircraft may be dan-
gerous to the operation of the aircraft, disrupt the
wireless telephone network and may be illegal.
Failure to observe these instructions may lead to sus-
pension or denial of telephone services to the offender,
or legal action or both.
Emergency Calls
Important! This phone, like any
wireless phone, operates using radio signals,
wireless and landline networks as well as
user-programmed functions which cannot
guarantee connection in all conditions.
Therefore, you should never rely solely upon
any wireless phone for essential communica-
tions (e.g. medical emergencies).
Remember, to make or receive any calls the phone
must be switched on and in a service area with ade-
quate cellular signal strength. Emergency calls may not
be possible on all wireless phone networks or when
certain network services and/or phone features are in
use. Check with local cellular service providers.
To make an emergency call:
1 If the phone is not on, switch it on.
Some networks may require that a valid SIM card is
properly inserted in the phone.
2 Press and hold the key two times for several
seconds to ready the phone for calls.
3 Key in the emergency number for your present lo-
cation (e.g. 112 or other official emergency num-
ber). Emergency numbers vary by location.
4 Press the key ( Call ).
If certain features are in use (Keypad lock, Fixed Dial-
ling, etc.), you may first need to turn those features off
before you can make an emergency call. Consult this
document and your local cellular service provider.
When making an emergency call, remember to give all
the necessary information as accurately as possible.
Remember that your wireless phone may be the only
means of communication at the scene of an accident -
do not cut off the call until given permission to do so.
Important User
Information
This section explains how to deactivate the EFR CODEC
should you find that it is difficult to make or receive
calls when travelling and roaming onto another net-
work.
1. Introduction
The Nokia 5110 (GSM) comes equipped the latest co-
dec and audio technology for superior sound and voice
quality.
Currently, there are three different codecs defined for
GSM/PCN:
• full-rate (FR)
• enhanced full-rate (EFR)
• half-rate (HR)
The Nokia 5110 and 5130 phone can support all these
codecs.
The FR codec is supported by all GSM and PCN cellular
networks and phones.
The network automatically selects which codec is used,
FR or EFR (if supported by the network).
The Nokia phone supplied within this sales package has
the EFR codec activated to so that you can automati-
cally enjoy the benefits of EFR if supported by your
network operator. Currently only some networks sup-
port the EFR codec in addition to the FR codec.
2. Deactivating/Activating
The EFR Codec
The Nokia N5110 fully meet and comply with all EFR
codec and relevant compatibility specifications.
However, as a result of some networks not yet comply-
ing with the latest specifications you may find it im-
possible to make or receive calls, if the EFR codec is
activated, e.g. when you are visiting or roaming in a
foreign network.
