Missing backlight- missing LED indication- missing sounds.
If your Explorer terminal does not show backlight, LED incation and sounds are mission it is highly likely that the terminal has been switched to Stealth Mode!
In order to get the Explorer back to normal functionality - make sure that Stealth Mode is not activated. To deactivate the stealth mode press C+OK E.
"Enabling Stealth Mode" will not put the Explorer into Stealth Mode directly, it only enables the use of the Stealth Mode function.
Note: If Stealth Mode is activated, and the function then is disabled, it will not be possible to deactivate the Stealth Mode, before the Stealth Mode function has been enabled.
