5. Basic functions
Turning the phone on or off
Press and hold the key for one second.
Note: If the phone asks for a PIN code, see ‘PIN code’ on page
60. If the phone asks for a security code, see ‘Security code’
on page 61.
NORMAL POSITION: Hold the phone as you would any other
telephone, with the antenna pointed up and over your
shoulder.
TIPS ON EFFICIENT OPERATION: As with any other radio
transmitting device, do not touch the antenna unnecessarily
when the phone is switched on. Contact with the antenna
affects call quality and may cause the phone to operate at a
higher power level than otherwise needed.
WARNING! Do not switch on the phone when wireless phone
use is prohibited or when it may cause interference or danger.
Checking signal strength
Your phone operates on radio waves. Radio signal coverage
is maintained by a wireless network, and the quality of calls
on your phone depends on the strength of the wireless radio
signal.
Get a strong signal
When you are at the start screen (see page 9) or in
a call, the strength of the radio signal is indicated
by the signal indicators on the left side of your
phone’s display. These indicators scroll as the
signal strength increases and decreases.
To improve your phone’s reception, try moving your phone
slightly. If you’re inside a building, move toward a window.
