when using data
connection
Your display will go dark if
untouched for a period of time
when using data connection. To
turn on your LCD screen, just
press the Lock/Power hard key.
11. Do not connect your
phone when you
power on/off your
PC
Make sure you disconnect your
phone and PC via data cable as
it might cause errors on your PC.
12. Hold your phone
upright
Please hold your phone straight
and upright, as with a normal
phone. The LG-P990 has an
internal antenna. Be careful
not to scratch or damage the

cause loss of performance.
While making/receiving calls or
sending/receiving data, try to
avoid holding the lower part of
the phone where the antenna
is located. This may affect call
quality.
13. If the screen freezes
If the phone does not respond to
user input or the screen freezes:
Remove the battery, insert it
again and switch on the phone.
If it still does not work, please
contact the service centre.
