• Diagnostics Password: This password is needed to unlock the Diagnostics Setup entry
on the System Setup screen (shown in Figure 3-46, on page 3-54), if it is locked.
The frequency select and frequency offset entries on the exciter setup screen are
locked when the diagnostics setup is locked.
If either password change screen is entered, an alpha/numeric touch keypad is displayed

rect case to unlock a function.

lock that function.

password can be retained by pressing Cancel.
