Troubleshooting
The commonly encountered failures and their solutions are listed below. When you
encounter those problems, please solve them following the corresponding steps. If
the problem remains still, please contact RIGOL and provide your device
information (System  Information  System Info).
1. The screen of the RF signal generator is still dark (no display) after
pressing the power key:
(1) Check whether the fan is running;
—
If the fan is running but the screen is dark, the screen connecting wire
might be loose.
—
If the fan is not running, the instrument does not start successfully and
please go to step (2).
(2) Check whether the power is correctly connected and the power switch is
really on.
(3) Check whether the fuse is burned out. If the fuse needs to be replaced,
please use the specified fuse (AC 250V, T2A).
(4) Restart the instrument after finishing the above inspections.
(5) If it still does not work correctly, please contact RIGOL.
2. The screen is too dark and cannot be seen clearly:
(1) Check whether the brightness setting of the LCD screen is too low.
(2) Press System  Display  Brightness and use the numeric keys or
up/down direction keys to adjust the brightness of the LCD screen of the RF
signal generator to a proper value.
3. The RF signal generator is locked:
(1) Check whether the RF signal generator is in remote control mode (in remote
control, is displayed in the status bar of the user interface). Pressing
Esc can exit the remote control mode and unlock the front panel.
(2) Check whether the RF signal generator is in local mode with the screen
being locked (when the screen is locked, front panel operations are not
available). Pressing Esc can unlock the screen and exit the locking state.
(3) If progress bar is displayed on the screen of the signal generator, some
operation is in progress. For example, when saving a file, the progress bar
will be displayed indicating that the save operation is in progress. At this
point, the front panel is locked.
(4) Pressing Preset or restarting the signal generator can also unlock the
instrument.
