All LEDs remain off when the
device is powered
• No power is being applied to the CTM-ONE
•
Check power supply make sure min. 9 VDC is being supplied
• The device is in standby mode
• Ensure the standby signal is connected to greater than 9VDC
• Ensure the supply voltage is greater than 9VDC.
• Remember that the device is designed to go into standby mode if

PWR LED ON all other LED
OFF
• Device is booting Linux
rebooting every 4 minutes
with no user input.
Only PWR LED and GPS LED
(solid or flashing) are on.
• Incorrect cellular device is configured. The CTM-ONE is
configured by default to auto connect to a cellular network. If
the CTM-ONE determines that communication with the internal
cellular radio module or device is not working, it will attempt to
reset the communication port; this will result in continual system
reboots if incorrect module/device is selected.
• No valid GPS fix. The GPS antenna requires a clear view of the sky
to obtain a valid GPS fix. The time to fix can vary from a few
seconds to several minutes depending on conditions.
•
GPS LED flashing has no impact on cellular connectivity.
• RF signal may not be available; CTM-ONE is located in an area of
no cellular activity.
• Cellular device is not registered on the network; make sure radio
module/device/SIM has been activated on the network.
• Incorrect configuration of internal radio module, ensure correct
device has been configured
