How the Fir Menu Works
Once in the function menu with the function-symbol you require on screen, press the
ENTER key. (See Figure 1.)
A cursor (highlighted symbol or number) can be moved from one selection
to another by using the UP and DOWN keys. (See Figure 2.) Pressing ENTER
will cause the selection to flash.
When flashing use the UP and DOWN keys to adjust it.
When you have adjusted the parameter to an acceptable level press the ENTER key. Th e adjusted
parameter will be stored. In many cases a tick (
ü
) will appear to confirm the action.
Although there is a variation in complexity of some functions, this basic concept of selection, adjustment and
confirmation is common throughout this instrument.
You can abort a selection by pressing the ESCAPE (Esc) key.
