The
Service Provider (SP) Lock menu is used to lock the cell phone to the
SP's
SIM card. Once the cell phone is locked to a specific operator, if one
inserts
a SIM card from a different operator the phone will refuse to accept it!
The
cell phone will however accept another SIM card from the same operator.
To
activate/deactivate this lock one needs a special secret code that is not
available
to the end user.
Here is how to activate the menu:
<**<
Lock to Network? if pressing yes you have 5 attempts
to
enter NCK.
<**<<
Lock to Network subset? if pressing yes you have
5
attempts to enter NSCK.
Warning:
Your phone can be locked to a service provider FOREVER by doing this!
If
an invalid code is entered all five times, the menu will exit and be deactivated!
Any
further attempt to activate the NCK/NSCK lock Menu will result in the response
"Not
allowed"! However the NCK/NSCK lock can be recover through a direct clearing
in
the EEPROM.

Short
description
1:
it is for best external power supply, to charge the phone battery.
The
external power supply alone without the phone battery DOES NOT switch on!
Suggested
voltage 7.2V with 600mA at least.
2:
The RS232 serial line input at TTL (0/5V) level.
When
the phone is on, this pin is at "0", against any logic.
Connect
your interface RS232/TTL even if its output is 1!!!
3: GND digital
4:
It is the RS232 serial out put at level TTL (0/5V). When the
phone
is switched on this pin is at 1 (this seems logical!).
5: +5V output with phone on. Usable provided that few mA are absorbed.
6:
Mode test. As a general rule is at 0. To switch in test mode, switch the
cellular
off, set the pin at 1 (+5V), switch the phone on.In this mode the serial
line
works at 115200 instead of the standard 9600.
7:
Mute. Normally at 0, it goes at 1 while scrolling or during a conversation.
Useful
to mute the possible ear breaking radio!
8:
if open, the internal microphone and loudspeaker are on. If at 0, the external
ones
are enabled.
9: GND analogic
10:
The function of this pin is a mystery. It seems like a microphone and
loudspeaker
attenuates when at 0.
11: BF in
12: BF out
