What to do if the Cellular LED is off on my Cypress Solutions Transmitter?
- AAshley KerrAug 10, 2025
If the Cellular LED is off on your Cypress Solutions Transmitter, it could be due to several reasons. First, the CTM ONE might be in an area with no cellular activity, meaning no RF signal is available. Second, the cellular device may not be registered on the network, so ensure the radio module/device/SIM has been activated. Finally, there might be an incorrect configuration of the internal radio module; ensure the correct device has been configured.
