Hardware Issues

The table below contains information on which hardware related issues are covered by the warranty service and which issues are not:

Hardware issue Does FM need to be sent to warranty? Remote connection status

Device does not start. LED does not blink at all when device is powered up (10-30 V DC);

  • If client ensures that device does have 10-30 V DC power supply and still does not start, such device should be sent to warranty.

YES, if this issue is true

NOT REQUIRED

Visible physical damage (FMXXXX damaged, GPS antenna damaged...):

  • Visible physical damage on device case;
  • Visible physical damage on device PCB;
  • Visible deformation of internal battery;

YES, if this issue is true

NOT REQUIRED

Visible physical damage (FMXXXX damaged, GPS antenna damaged...):

  • Visible physical damage on device case;
  • Visible physical damage on device PCB;
  • Visible deformation of internal battery;

YES, if this issue is true

NOT REQUIRED

  • Visible physical damage on GPS antenna;
  • Visible physical damage on cellular antenna;

NO, if at least one issue is true, offer to change an antenna

NOT REQUIRED

Digital input is not working:

  • Connect DIN to power supply „+“, and check if DIN status changes. If not – send to warranty

YES, if this issue is true

NOT REQUIRED

1-wire short circuit:

  • Check 1-wire device type (maybe not supported device (ibutton, temp. sensor);
  • Check connection scheme;
  • Check terminal log (overcurrent message);
  • Measure voltage on 1-wire PWR and GND (should be 3.6V);

YES, if all the points are false, but FM still does not send data

IS REQUIRED

No GPS (GPS overcurrent, physical GPS antenna damage):

  • Check terminal log, look for overcurrent messages;
  • If overcurrent message is still present after GPS antenna change – send FM to warranty;
  • If overcurrent message is not present after GPS antenna change – change GPS antenna;

YES, if overcurrent message is still present after GPS antenna change

IS REQUIRED

  • No overcurrent messages in log, but still no GPS FIX.
  • Make sure GPS antenna is seeing clear sky;
  • Check NMEA log .log_nmea:x [0- disable; 1- enable] (May be no signal);

If another FM device gets GPS FIX with the same antenna – send device to warranty.

YES, if another FM device gets GPS FIX with the same antenna

IS REQUIRED

Sim card failure. FM does not see SIM card (bended sim holder, 3G sim card):

  • Check SIM card itself, if there is no physical bending;
  • Check if SIM card is seen by cell phone or other FM device;
  • Check if sim card is 2G (GSM) capable;
  • Check modem version (.info), try updating modem to the latest one, if modem version is old;
  • Check if PIN code is not set;
  • Check if device is working with another SIM card, another operator SIM card;
  • Check if GSM antenna is connected;

YES, if none of the mentioned points helps

IS REQUIRED


Firmware Issues

The table below contains information on which firmware related issues are covered by the warranty service and which issues are not:

Firmware issue Eligible for warranty? Remote connection status

Device is in boot mode (status LED is blinking fast) – send instruction for device recovery.

YES, if unable to revocer device manually

REQUIRED

Firmware blocked (security firmware) – check firmware description, if it is possible to reflash this firware to base FW.

YES, if unable to reflash to base firwmare

NOT REQUIRED

Modem failure (Modem initializing, Modem Seems to be Dead).

YES, if the solution does not help

IS REQUIRED



Recommended course of action when firmware issues are encountered is to contact your sales representative if the device was purchased directly from Teltonika or contact Teltonika support if VIP HelpDesk access is provided to you. If you purchased the device elsewhere, contact the distributor that sold you the device.

IMPORTANT: in any of the defined cases, please contact your sales representative before sending the device(s) to warranty.
