Signal strength LEDs
The signal strength LEDs are located on the right side of the back panel:
Each lit up LED represents a different value of the gateways current signal strength in RSSi:
No. of lit up LEDs Signal strength value
0≤ -111 dBm
1 -110 dBm to -82 dBm
2 -81 dBm to -52 dBm
3 ≥ -51 dBm
The signal strength LEDs can also be used as a time indicator for holding the reset button.
When you press and hold the reset button, if there is a User's default configuration configured on
the device, you have to hold it pressed for 6 seconds (by default) to initiate a User's default
configuration reset and 12 seconds (by default) to initiate a Factory reset. Otherwise, it is only
necessary to hold the reset button for 6 seconds to trigger a Factory reset. If the button was held
down longer than 20 seconds (by default) no action will be taken.
While holding the reset button each lit up signal strength LED indicate that a period of two seconds
has passed. In case with TRB245, when all 3 signal strength LEDs are lit up, they represent that 6
(LED number multiplied by 2) seconds have passed since you pressed down on the reset button.
After releasing the button at one of the reset periods, all 3 LEDs will start blinking every 1 second.
This signifies that the router has begun the reset.
