Touch screen
To control your device, lightly touch the screen with your fingertips. The screen does
not respond when you use your fingernails.
If your fingertips are cold, the screen may not respond to your touch.
Important: Avoid scratching the touch screen. Never use an actual pen, pencil,
or other sharp object on the touch screen.
Noise cancellation
If you are calling from a noisy environment, your device filters out background noise to
make your voice sound clearer to the person at the other end of the line.
Noise cancellation is not available when using the loudspeaker or a headset.
For the best noise cancellation, hold the device with the earpiece to your ear and the
main microphone towards your mouth. Do not cover the secondary microphone at the
back of the device.
Insert the SIM card
Follow the instructions carefully, to avoid damaging the back cover.
1 To open the back cover, slide it toward the top of the device.
2 Insert a SIM card. Make sure the contact area of the card is facing up.
Push the card in, until it locks into place.
