For remote programming, a user-defined password can be used to disable pro-
tected commands. Most Model 622x commands are protected. From the front
panel, the password can be cleared using the following key-press sequence:
Press COMM > Select PASSWORD > Select YES to clear the password
See Section 10 of the Reference Manual for details on password.
Cursor control is provided by the Cursor Keys located under the rotary
knob.
When at a menu level that requires an item to be selected, the Rotary
Knob can also be used for cursor control. Turn the knob clockwise to move
the cursor to the right, and turn it counter-clockwise to move the cursor to
the left.
With a value displayed, value adjust can be performed using the Rotary
Knob. Turn it clockwise to increment a digit, and turn it counter-clockwise
to decrement a digit.
Pressing the ROTARY KNOB performs the same function as the ENTER
key. Press the knob to select or open a menu item, or to select a displayed
value.
