~ Installing the Memory Card
Your phone takes a MicrosD memory card of up to
32GB.
To install a memory card, turn the phone off then re-
move the back cover and take the battery out. Now
insert the memory card in the slot.
~ Turning the Phone On and Off
To turn the phone on, press and hold the ON/OFF
button.
If your sIM card is locked, you must enter the correct
PIN code to unblock the sIM card when the phone is
powered up. Your PIN is supplied by your operator;
if you did not receive it or have lost it, please contact
them.
When the PIN is entered incorrectly three times, the
mobile phone is blocked and has to be unblocked
using your PUk (this is supplied with the sIM card;
if this is not the case, you should contact your phone
operator).
To turn the phone off, press and hold the ON/OFF but-
ton until the menu opens, then press on switch
Off.
Now press Ok to confirm.
The phone vibrates when it is shut down completely.
