When you press the Shift key, the Shift annunciator (near the bottom-right
corner of the display) activates. When you press the Menu (Reset/Local) key,
the Shift annunciator goes off, and the first menu item is displayed. If you have
not previously invoked the Menu since you last turned the instrument on, the
first menu item is REF OSC, the Reference Oscillator.
The flashing annunciator ( ) in the display reverses direction to indicate that
you can now change the setting by pressing either the up-arrow key or the
down-arrow key. In the case of the Reference Oscillator function, which has
only two possible settings (INTernal and EXTernal), pressing either the up-
arrow or the down-arrow has the same effect (it toggles the setting from INT to
EXT or from EXT to INT).
