7.3 Repairs

Should you need some service interventions, please contact the 2N TELEKOMUNIKACE a.s. Technical Support via e-mail: techsupport@2n.cz or phone: (+420)900300300.

The device repairs may be made by an authorised servicing centre or the manufacturer only.

You can also use the error log for troubleshooting. It is a part of the memory where errors are recorded if detected. GSM connection troubles, terminal disconnection from the server and communication errors in the GSM/UMTS data channel can be detected in this way. Use the following command:

at^scerr?

The command writes out the error buffer state.

• ^SCERR: 72> 8,10
• ^SCERR: 73> 8,10

at^scerrclear

The command clears the error buffer.
