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 7110 (GSM) come equipped the
latest codec 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 7110 phone can support all these
codes.
The FR codec is supported by all GSM 900/
1800 cellular networks and phones.
•
Do not paint it. Paint can clog the
device's moving parts and prevent proper
operation.
•
Use only the supplied or an approved
replacement antenna. Unauthorised
antennas, modifications or attachments
could damage the phone and may violate
regulations governing radio devices.
•
If the phone, battery, charger or any
accessory are not working properly, take
them to your nearest qualified service
facility. The personnel there will assist
you, and if necessary, arrange for service.
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 7110 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 call, if the EFR codec is activated, e.g.
when you are visiting or roaming in a foreign
network.
