Preset

While button 

5

 is operated one reaches the 

preset

mode

 (see chapter 2 concerning the term 

preset

). In

this state the displays of the third and fourth  frequency
divider show “

Pr

" resp. the number of the preset

currently selected (e.g. “

45

", see fig. 6a):

Fig. 6

(a): display of the current preset
(b): store preset with new preset number

To 

select a new preset

 the up/down buttons 

2

 and 

3

of the fourth frequency divider are used while the
preset button 

5

 is operated until the desired preset

number appears in the fourth display.
As soon as the preset button 

5

 is released the module

returns to the normal mode. The displays show the
divisors of the new preset and the divisors can be
adjusted with the corresponding up/dow buttons.

Store

The store button  

6

 is used to 

store presets

. The

following steps are required to store a new preset:

Operate the preset button 

5

 and keep this button

pressed down (see fig. 6a).

The up/down buttons 

2

 and 

3

 are used to select

the preset number in which the current preset will
be stored (preset button 

5

 remains operated).

Pressing the store button 

6

 (preset button 

5

 still

remains operated) causes the storage of the cur-
rent preset into the preset number selected. In the
upper displays appears "

St

" and "

or

" as confirma-

tion of the storage process (see fig. 6b).

Pay attention not to select a preset num-
ber that already contains preset data you
may need in the future. Any former preset
data in the selected preset number are
deleted!

As soon as both buttons preset 

5

 and store 

6

 are

released the module returns to the normal mode. The
displays show the divisors and the divisors can be
adjusted with the corresponding up/dow buttons.
