Bosch GSM 509 - Manual (Page 17)

Enter the Setup menu by pressing »MENU«
Select »Security«
Entering the Security menu gives you different
possibilities of preventing misuse of your SIM
card and your telephone, e.g. if your phone is
lost or stolen:
»PIN code«
»SIM lock«
»Network password«
»Encryption indication«
»Line lock«
PIN code
In this sub menu you can select a PIN code (4
to 8 digits) to be entered each time you switch
on your phone. If you have already selected a
PIN code you also have the choice of disabling
it again or changing it to another code.
If you enter an invalid PIN code three times,
your SIM card will be blocked, and to unblock
it you have to enter the PUK code supplied by
your network operator. This procedure prevents
unauthorised persons from working out your
PIN code by repeatedly entering different
combinations of numbers.
The display will inform you how many tries
you have left before the SIM card is blocked. If
you enter an invalid PUK code 10 times, your
SIM card will be permanently blocked and you
have to contact your network operator.
Some SIM cards use a PIN2 code for access-
ing special functions. Contact your network
operator for further information on PUK2 and
PIN2 codes.
SIM lock
You can link your telephone and your SIM
card together. This means that if, for instance,
your phone is stolen, it cannot be used together
with another SIM card. To enable this feature
you just turn it on and then enter a 6 to 16-digit
code of your own choice.
For your own sake remember to write down this
code to be able to deactivate the lock at a later
time.
You have 10 attempts before the phone is
blocked.
Network password
If you subscribe to a call barring service your
network operator will have supplied you with a
4-digit password. If you want to change it,
select this sub menu.
Encryption indication
Encryption means that the network encrypts
the conversations to make it difficult for
unauthorised persons to listen in on them. If
you connect to a network which does not
support encryption, you will get a warning in
the display when trying to make a call. You
have the option of turning on and off the net-
work warning by selecting this sub menu.
Line lock
If you have Alternate Line Service on your
SIM card you can restrict the outgoing use to
only one of these lines. Activate the line lock in
this sub menu and enter a 4 to 8 digit lock code
of your own choice. To shift back to the other
line you have to re-enter this code.
Enter the Setup menu by pressing »MENU«
Select »Call timers and charge«
The Call timers and charge menu offers you
the possibility of checking duration and cost of
your calls in different ways:
»Last call«
»Total calls«
»Reset timers and charge«
»Show timer and credit«
»Call charge«
Last call
Informs you about the duration of your last
call.
You may also be able to see the cost of
your last call, but this feature demands that
your network supports it, and that you have
entered a unit price and the actual currency in
the sub menu Call charge (see below).
Total calls
Informs you about the duration of all calls
made with your SIM card since the timer was
last reset.
The conditions for also seeing the
cost of these calls are identical with the
conditions mentioned above in the Last call
sub menu.
Reset timers and charge
Resets your timers, so that the call duration
counter is set to zero. You may be asked to
enter your PUK2/PIN2 code.
Show timer and credit
You can select whether you want the Show
timer function to be on or off. If you turn it on,
your telephone will display the actual duration
of an ongoing conversation.
The conditions
for also seeing the cost are identical with the
conditions mentioned above in the Last call
sub menu.
Call charge
If your network supports this feature, this is
where you deal with the call charge. To enter or
change call charge and currency you will be
requested to enter your PUK2/PIN2 code. You
have the following options:
»Call charge maximum«
»Call charge unit price«
»Call charge currency«
»Call charge remaining«
Call charge maximum
Gives you the option of entering a maximum
call charge limit, so that when this maximum
has been reached no more phone calls can be
made.
Call charge unit price
This is where to enter the unit price (check with
your network operator).
Call charge currency
This is where to enter the currency of your call
charge.
Call charge remaining
The telephone can inform you about the
remaining call charge balance, if you have
entered a maximum call charge limit.
