Garmin Fenix 2 service menu
Have you ever wondered how long ago you last reset your Fenix 2, if the ROM and RAM are OK, or if all the pixels are in proper working order? You can find out!
To enter the service menu, power off the device (press and hold the upper-left “Light” button) and choose “Power off”.
Then press “Light” and “Up” (middle-left button) simultaneously. The first of the screens will appear. You can cycle through them by pressing the Start/Stop button (upper-right).
To test the backlight: When Light is pressed, Backlight will display 100% here.
Then a whole lot of graphics test screens follows.
When you’re done, press the Light button to power off the Fenix, and then the Light button again to power it on in normal mode.
