Preparing Your Phone for Use
7
The PIN
Most SIM cards are supplied with a security code or PIN (Personal Identity
Number), which you need to access the network. Every time you turn on your
phone, it prompts you to enter your PIN. You will find your PIN in the infor-
mation from your operator.
You may need your PIN when you want to change the settings in your phone.
Furthermore, some operators may have services that require a second PIN,
your PIN2.
You should be careful with your PIN, since it is your protection against
unauthorized use of your subscription.
If your PIN is entered incorrectly three times in a row, the SIM card is
blocked. If this happens, you can unlock it by using your PUK (Personal
Unblocking Key code), which you also get from your operator.
The R250s PRO comes with a nickel metal hydride (NiMH) battery. The
battery is not charged when you buy your phone, but there may be enough
power to turn the phone on. We recommend that you charge the battery before
you use the phone for the first time.
The battery is specially designed for the R250s PRO. The battery has a special
locking mechanism that prevents it from falling off if you should drop the
phone on the ground.
The battery is equipped with a special rubber sealing to prevent leakage into
the phone. With the battery and antenna properly attached, the phone is dust-
and water-resistant. The phone can be used outdoors, even if it is raining and
the phone will not be damaged if you use it in a dusty environment.
Use only Ericsson original batteries. By using other batteries you risk damag-
ing the phone and will void the warranty.
