Make sure that the battery is properly installed and charged.
Make sure that the contacts on the battery and the charging stand are clean.
The battery charge may be too low for operation. Check the display and listen
for the low battery warning tones. Charge the battery as described in
”Battery” on page 27. If the NOT CHARGING message is displayed, the
charging is suspended. In that case, check that the temperature of the battery
is not above +45°C (+113°F). Wait for a while, disconnect the charger, connect
it again and retry. If charging still fails, contact your local Nokia dealer.
