If the device flashes orange, it is not able to log into a mobile phone network. This may be due to the following reasons:


The device has just been switched on and is still searching for a mobile network (no longer than three minutes).

No mobile network is available at the location of the device.

  • The SIM card of the device is defective.
  • The SIM card of the device is blocked
  • The SIM card of the device is not inserted correctly and therefore has no contact
  • The SIM card of the device is dirty and therefore has no proper contact
  • The device is defective
  • The device has a software problem (older firmware does not restart automatically in the event of an error)
  • The device has a configuration problem


Before contacting our support team, please carry out the following measures


  • Ensure that the device is charged.
  • Switch the device off and on again. If it then connects, update to the latest firmware (via the portal). If there is no newer firmware, restart the device via the portal.
  • Check the position of the SIM card by removing and reinstalling it. Check the SIM card for stains on the gold contacts. Clean the SIM card with isopropyl alcohol.


If these measures are unsuccessful, please contact support, preferably by ticket (create here in the portal) or by e-mail (support@climax.de) and then send us the device.


What could be the cause?

  • The device has been dropped and the SIM card has lost contact with the device (removing and reinserting the SIM card usually helps)
  • The device has been exposed to water and is now defective or the SIM card has lost contact (we replace the handset)
  • There have been changes to the mobile network at the subscriber's location, which means the device can no longer connect. The device may work again at a different location (we reset it to factory settings)
  • The device has been switched off for too long and stored with an empty battery and has therefore lost its basic configuration or the memory content is damaged (we charge the device and reset it to factory settings)
  • The mobile phone module of the device is defective (we will replace the handset)
  • The SIM card is defective (we will replace the SIM card)


In many cases, we receive devices from customers that work perfectly for us. Nevertheless, we take your problems seriously and carry out all the measures that we would also carry out if the device had no reception. This usually enables us to rectify the fault, even if we could not actually reproduce it. Afterwards, please test the device in the same environment in which the error occurred before you use it again with an end customer.
