The selected PIN is now activated. The next time you switch on the R&S FSH, you must enter the PIN 
before you can operate the instrument. If you enter an incorrect PIN , the R&S FSH again prompts you 
for the PIN code. After three attempts with an incorrect PIN, the R&S FSH prompts you for the master 
PIN. 
Note:  The R&S FSH comes with labels reading ‘PIN Code protected’. If the instrument is 
protected with a PIN, affix one of these labels to the instrument. This warns unauthorized 
users that they cannot operate the R&S FSH.
