To Change the Security Code<br />
To Change the Security Code<br />
• To change the security code, you must first unsecure the instrument,<br />
and then enter a new code. Make sure you have read the security code<br />
rules described on page 77 before attempting to change the security<br />
code.<br />
• To change the security code, first make sure that the instrument is<br />
unsecured. Go to the SECURE CAL entry, enter the new security<br />
code, and press (the instrument is now secured with the new code).<br />
Changing the code from the front panel also changes the code as seen<br />
from the remote interface.<br />
