In some cases it is recommended to perform RFD procedure to regain control of the device: 

•

 

If device becomes unstable and you want to recover it 

•

 

If device settings are not matching available display and as a result no video is visible 

•

 

If device settings do not enable normal keyboard/mouse interaction 

 

 

Jack PC should be booted in Safe Mode state in order to reset the device to the factory-
defaults or in order to upgrade the device’s firmware. 

 

 

 

 

Follow these steps to boot the device in to Safe Mode and to reset it to the factory-default 
settings: 

•

 

Check the device is ON (Power/Fail LED should be steady green). 

•

 

Use a paper clip (or similar tool) and press and hold the RFD Button 
and at the same time press the Reset-button for one (1) second and 
release it, without releasing the RFD button – keep holding it. 

•

 

Wait few seconds until the  Power/Fail LED will  blink 

  and 

change to 

 only then 

release the RFD button.  

•

 

The device should be now static, with only the  Power/Fail LED 
lighting in 

, you should not proceed to the next step it the 

Power/Fail LED is not steady 

.  

•

 

Now, press the RFD button for one (1) more second and release it, 
and (the Power/Fail LED would turn 

) and immediately press 

and hold it again (like doing a double click) - keep holding until the 
progress bar displayed on the monitor (the system-splash screen) 
has finished loading (the display might turn off and on) and until you 
see the log-on screen showing (SAFE MODE) on the title. 

•

 

When a hardware reset is initiated as described above, the device 
has now boot into safe-mode state. This mode is designed to allow 
the device to complete boot in any scenario. When device is in safe-
mode, only basic OS components are loaded and therefore device 
settings are unchangeable. Administrators can only perform firmware 
or hotfix installation during this mode.  

•

 

In order to reset the device to factory default, on the WBT screen 
press  (using  the mouse) the "Reset …" button, and Check "Clear 
Device Settings" and/or "Remove Plug-ins" if you wish them to be 
removed. (it  is  recommended you keep installed plug-ins by  un-
checking the "Remove Plug-ins" option, unless you have a reason 
for removing then (corrupt installation, upgrade etc.) – after selecting 
the desired option  – click on YES in order to reset the device. The 
device will then automatically restart. 

•

 

If you want to exit the safe mode without resetting to factory defaults, 
simply, reboot the device by pressing the Reset button (on the Jack 
PC unit). 

 

Note: You will need a paper clip in order to press the RFD button (marked on the unit with 
explanation mark). The device should be connected to a monitor, and a mouse, and the 
device should be powered (by PoE or an external power supply).
