11. Unlocking the screen when
using a data connection
Your display goes dark if untouched for a
period of time when using a data connection.
To turn on your LCD screen, Press lock key.
12. Hold your phone straight up
Hold your mobile phone straight up, as you
would a regular phone. The LG-E510 has an
internal antenna. Be careful not to scratch
or damage the back of the phone, as that
causes loss of performance.
While making/receiving calls or sending/
receiving data, avoid holding the lower part
of the phone where the antenna is located.
Doing so may affect call quality.
13. When the screen freezes
If the screen freezes or the phone does not
respond when you try to operate it:
Remove the battery, reinsert it, then turn the
phone on. If it still does not work, please
contact the service centre.
