If you fail to unlock the R&S FSH with the OEM Master PIN, the R&S FSH will
force a reboot of the software until you enter the correct OEM Master PIN.
Firmware update
If the R&S FSH is protected with a PIN, a firmware update is only possible after you
have entered the correct PIN.
In the initial state after delivery, PIN protection is turned off. So if you want to protect
the R&S FSH, you have to turn it on manually.

► Press the "Instrument Settings" softkey.
The R&S FSH shows the "Instrument Settings" dialog box.
► Select the "PIN Code Protection" menu item.
► Press ENTER
The R&S FSH opens an input field to define a new PIN.
► Enter a 4-digit PIN.
The R&S FSH opens an input field to confirm the PIN.
► Enter the 4-digit PIN again.
If the PIN confirmation was successful, the R&S FSH shows a corresponding
message and activates PIN protection. In that case, you have to enter the PIN
every time the R&S FSH boots.
If the PIN confirmation was not successful, the R&S FSH shows a corresponding
message and does not activate PIN protection. In that case repeat the last steps.
