Touch screen
To control your phone, 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 phone 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 phone with the earpiece to your ear and the
main microphone towards your mouth. Do not cover the secondary microphone on the
back of the phone.
Insert the SIM card and battery
Important: Do not use a mini-UICC SIM card, also known as a micro-SIM card, a micro-
SIM card with an adapter, or a SIM card that has a mini-UICC cutout (see figure) in this
device. A micro SIM card is smaller than the standard SIM card. This device does not
support the use of micro-SIM cards and use of incompatible SIM cards may damage the
card or the device, and may corrupt data stored on the card.
Follow the instructions carefully, to avoid damaging the back cover.
1 Pull the back cover release latch towards the bottom of the phone, and remove the
cover.
