5. Light indicators
The Nokia 30 GSM Connectivity Terminal has three light indicators (LEDs), which form the terminal’s 
user interface. The LED display shows the field strength and the terminal status. The LEDs appear in two 
colours - red and green - indicating the state of the Nokia 30 GSM terminal in three different 
conditions:
• Start-up 
• Normal operation
• Special operation
Note: All three LEDs can also be configured using the Nokia 30 
Configurator software application so that they do not show any status 
and remain off during operation.
