Si, pare che si configuri automaticamente.

 Si, pare che si configuri automaticamente.
Sei sicuro? Io ho letto in alcune FAQ che i 688 già abilitati all'EFR
riportano una scritta sulla scatola dove si precisa la cosa. Se questa
scritta non c'è, allora si possono abilitare portandoli gratuitamente in
un centro assistenza. Qualcuno sa di più? In particolare, se qualcuno
conosce il codice per attivare nel 688 l'EFR o l'HFR, mi servirebbero in
Germania!

australiane, che perciò allego, scusandomi per la lunghezza.
628/688Frequently Asked Questions
                                                           13 April 1998
                                                            Version 0.1
Lithium Ion Battery
At this stage, Ericsson has not introduced Lithium Ion batteries to
their range. Customer satisfaction with the current Nickel Cadmium and
Nickel Metal
Hydride seems to be quite high, with additional standby times derived by
switching to the lower oprating voltage of 4.8 volts as opposed to 6.0
volts in the
388. This has upset current 337 and 388 users as if they wish to
upgrade, all new accessories are required, including a new car kit !
Standby times are also increased with the use of a Phase 2.0 SIM card,
and the use of DTX and RTX on the network in use. The network
performance also
affects standby time as the frequency of the polling can be decreased to
provide more efficient battery usage.
Why should I upgrade from my current mobile telephone ?
The Ericsson 688 is compatible with the latest GSM Phase 2 features and
is very easy to use. The display has been improved significantly over
the previous
388 and now boasts 3 lines with 12 characters each. The size and weight
of the mobile make it extremely portable and convenient to carry in your
pocket or
purse. The 688 also usings Enhanced Full Rate Codec (EFR) to provide
significant gains in voice quality. Voices are reproduced with a wider
range of tones
and clarity.
The 628 is a huge improvement over the previous 318. The screen in still
one line, but this little classic boasts EFR which is a big feature. The
menu structure is
simple and effective. A great little mobile for first time users, or
those who don't want to spend a fortune.
The 628 and 688 share the same accessories as each other.
What is the latest software version for the 688?
The latest version I have been informed of is 9801xx which only serves
to correct a few spelling mistakes. If you are using a software version
970715 or earlier,
an upgrade is strongly recommended.
Details about a problem that Ericsson software version 970905 fixed is
described as "MS unable to find HPLMN if 30 or more competitor ARFCN+s
have
greater signal strength than the HPLMN." Translating to English, if
there are 30 or more channels belonging to other carriers which are
stronger than the
customer's home network, the phone will not be able to find the
customer's home network.
What is the latest software version for the 628?
Information to be provided soon !
How can I check which software version I have?
Key -> * <- <- * <- * <- <- * <- * 
Is it easy to upgrade to the latest version ?
Yes, BUT...... this should be done by an authorised Ericsson Service
Centre. Some Service Centres may refuse to do the upgrade unless a
specific fault is
evident. You could always tell them that the 970310 software you have in
your mobile have problems with the unconditional diversion.
How much does the upgrade cost ?
This will be about $A50, but various dealers or agents may charge more
or less. The good news is that if your phone is still under warranty,
you should be able
to get it done for free. Check with Ericsson in your country as to
availability and suitability.
How do I know if I have EFR enabled on my mobile ?
On the 628, EFR is not enabled by default. You need to visit an Ericsson
Service Centre for them to enable this feature, BUT at a cost. Current
charge in
Australia is A$30.
On new 688's being sold, the box should be clearly marked that EFR is
enabled. If not, or if you have an early version of the mobile, you can
go to an Ericsson
Service Centre to get the upgrade performed FREE OF CHARGE.
How long should by battery last in standby mode?
First of all, the amount of standby time you get will depend on your
talk time and the longer you spend talking, the less standby you will
get.
688 : Ericsson quote 40 hours for the standard battery and 36 hours
seems to be realistic.
628 : Same as above 
What talktime can I expect on my 628/688?
This will again vary from network to network and will also depend on the
condition of your battery. Typical figures again are about xxx - xxx
minutes.
Talk time is also affected by the use of EFR on the mobile. EFR leads to
an increase in battery consumption, but this is more than offset by the
gains when
using RTX and DTX.
How can I prolong the life of my battery ?
Always charge your new battery for at least 16 hours before use, longer
if possible. The first few charges and critical in the life of the
battery, and ideally the
battery should be recharged when fully discharged.
If possible, you should let a discharged battery stand overnight before
recharging.
Why is my battery standby so low ?
This can be a result of a number of factors. These include both making
and receiving calls/SMS messages, receiving broadcast messages, your
distance in
relation to a base station, how your providers network is configured and
what type of SIM card you have.
The first of these is mostly unavoidable, but remember that every minute
spent on your mobile will reduce your standby time by about 30 minutes.
Cell broadcast is where your GSM network can broadcast information to
all the mobiles in the area. The most common application for this
feature is to
broadcast the Cell ID information.
The location of base stations will affect performance dramatically. If
you are close to a site, your power consumption is reduced. The further
away you move
from the site, the higher you power consumption.
If you can get a Phase 2 SIM card, grab one. These cards will enter a
power standby mode and consume about 3mAh.
It always pays to have two batteries and alternate use of them.
Help ! My 628/688 is blocked.
Contact your SIM provider for your unblock code. Only they can assist
you. Do not try to guess this code as your SIM will become permanently
blocked after
a few unsuccessful attempts.
Blocking occurs when you input your SIM PIN, Phone Security code, or
Call Barring Password three times incorrectly.
Oops ! I lost my security code. How can I find that ?
If you have forgotten your security code you could always try the
default of 000000. If this does not work, you will have to take your
mobile to a repair agent
to get this reset. They will most likely require proof of purchase, and
will charge you for the privilege. Last time I checked, it was about
A$90 !
How can I find out my IMEI number ?
Take off your battery and look on the back of the mobile. The IMEI is
typically 15 numbers long and is on the sticker between the two bar
codes. If this is to
time consuming, key in *#06# and your IMEI is displayed on the screen.
Can I use my 628/688 with a laptop/PDA/PC...... ?
Certainly can ! You can use the DC24 Fax/Data PCMCIA card to connect to
a PC and some PDA's. This kit costs about A$500 and includes software to
manage the mobile.
If you own an Ericsson MC18 PDA running Windows CE or CE2, you just need
the connector cable to your mobile and

Non sono sicuro al cento per cento: ma al 70%. 
Lo ho scritto perche' cosi' e'
riferito sul volantino che lo pubblicizza:
"Predisposto per EFR: ottima qualita' audio".
Che abbia un'ottima qualita' audio e' comunque risaputo anche senza EFR.
Che cosa significhi "predisposto", in questo caso, non lo so.
Forse ha solo bisogno di una diversa versione software.
Speriamo prossima anche se la rete non ce lo consente ancora.

Ma l'half full rate non dovrebbe ridurre il consumo del 5% ?
Cmq da noi full rate, EFR o HRM ha poca importanza : finche'
i gestori non lo implementano.... nisba.
