6. Troubleshooting

First things to check

1 Check that the data cable is firmly connected to the terminal and to the PC or other compatible

device.

2 Check that the power supply is firmly connected to the terminal and to an AC wall outlet. 3 Check that the antenna is firmly connected to the terminal. 4 Disconnect the power supply from the AC wall outlet before you check that the SIM card is installed

properly.

Reception is poor

If there are problems with the reception, for example interruptions in the service, the signal may be too weak. Check the signal strength with the following AT command in the HyperTerminal connection window:

at+csq.

Troubleshooting

The response is

0 -113 dBm or less, poor coverage 1 -111 dBm, medium coverage

2...30 -109... -53 dBm at 2 dBm intervals, good coverage 31 -51 dBm or greater, excellent coverage 99 not known or not detectable

+csq: <rssi>, 99. The parameters for <rssi> are:

For example, response +csq: 31, 99 means that the signal strength is excellent.

If the signal is weaker than -95 dBm (the <rssi> parameter is 9 or less), move the terminal to another location. If the terminal does not receive a stronger signal, contact your service provider. Anexternal antenna may improve the reception.

The PIN code is blocked

If entering the PIN code fails three times successively, the code is blocked. You can unblock it by entering your PUK (Personal Unblocking Key) code. The PUK code may be supplied with the SIM card. If not, contact your local service provider for the code. If you lose the code, contact your service provider.

When the PIN code is blocked, light indicators 3 and 4 blink. To unblock the code, proceed as follows:

• In the HyperTerminal connection window, type the AT command

the PUK code is required, the response is

• Enter the PUK code with the command at+cpin="PUK","PIN" where PUK is your PUK code and

PIN your old or new PIN code. Press ENTER.
