2.1.2. Status indicator LEDs

GSR has 4 LEDs for showing events and status to the user:

!The led behaviour explained in this section is valid from version 1.13 onwards. Behaviour may vary for earlier versions.

2.1.2.1. Power LED (). GSR On/Off Status

Shows if the device is powered ON or OFF.

Device off	Device on
Led off	green Led

2.1.2.2. Signal bar LEDs (). Type of Registered Network

Displays the current mobile network state. Colour depends on the net type to which is connected, and the led blinking indicates ongoing call or sms.

No Network	2G Network	2G Ongoing Call/SMS	3G/4G Network	3G/4G Ongoing Call/SMS

2.1.2.3. Cloud LED (). NAYAR Services (VPN) Connection Status

The cloud LED indicates the GSR’s connection status to NAYAR services via the NAYAR VPN network. A blinking light indicates data transmission through the VPN.

No Nayar VPN connectivity	Nayar VPN Connectivity OK	Data transmission in progress

2.1.2.4. Battery LED ()

Displays battery level, with the following logic (versions 1.15.3 ans above):

• With a battery charge percentage above 10%, the battery LED will turn off.
• If the charge percentage is between 5% and 10%, the battery LED will blink.
• If the charge percentage is below 5%, the battery LED will remain solid red, and the GSR will enter power-saving mode. It will become unavailable to the user, as it suspends its standard functions and only maintains essential operations to remain powered on.

Battery level below 5%	Battery level between 5% and 10%	Optimal battery level
solid red Led	Blinking red Led	Led off

*Low battery level is according to EN81-28.

2.1.2.5. GSR with internal process ongoing

During the execution of an active internal process by the GSR unit, including but not limited to a software update or a device restart, the three LED indicators (Signal, Cloud, and Battery) will blink intermittently, without a requirement for simultaneous flashing. The unit will be non-operational during this process.
