10. Troubleshooting
Always check light indicators when problems are encountered. For the use of
light indicators, see “ Light indicators” on page 12.
First things to check
1 Check that all line cables are connected properly.
2 Check that the power supply is firmly connected to the Nokia 22 and the AC
wall outlet.
3 Check that the antenna is firmly connected to the terminal.
Light indicator 3 is blinking
The Nokia 22 is not in service. The terminal is not connected to the network, the
signal is too weak or the antenna is not connected to the terminal.
Replace the receiver and wait for a while, then try again. You can also move the
terminal to another location and then try again. See also “ No tone can be heard
when you lift the receiver” on page 46.
No tone can be heard when you lift the
receiver
Disconnect the power supply from the Nokia 22. Wait for 10 seconds. Reconnect
the power supply to the terminal. Operation succeeds when light indicator 3 is
lit continuously and you hear the dial tone.
Note: If the AutoPIN feature is disabled or the SIM card is installed for
the first time, the enter PIN code tone is heard. Enter the PIN code. After
that you should hear a dial tone within 30 seconds.
