AUTOMATIC RETURN TO HAND-SET REGISTRATION ('0'-PISTON):

While playing with a hand-selected registration, it may be necessary to use one or more combinations that have already

been ﬁxed. In this way, the original hand-set registration will be either cancelled or modiﬁed. However, by pressing the

'0' piston, the original hand-set registration will be automatically restored. If you wish to cancel this also, press the General

Cancel piston

'A'.

PRESETS

The Presets are activated through the tumb pistons PL.I, PL.II, T. The corrisponding led indicators are located on

the left of the display. Their contents are

ADDED to the hand-set or combination registration inserted. They are:

PLENUM I, PLENUM II, TUTTI.

PROGRAMMABILITY OF THE PRESETS

All the presets indicated above can be programmed by the organist in the following manner:

CRESCENDO (see note 3)

The Crescendo Pedal is located over the pedalboard, next to the swell expression pedal. The balanced pedal activates,

in gradual stages,

20 levels of sound intensity: from pp to ff. The Crescendo level is indicated on a digital display above

Manual II. The Crescendo operates on the entire organ, and its effect is

ADDED to the registration either hand-set or

drawn by a combination piston.

PROGRAMMABILITY OF CRESCENDO (see note 3)

The contents of the 20 levels of the Crescendo are programmable by the organist as follows:

Select the desired registration by means of the stop tabs.

Press and HOLD the 'F' thumb piston (to the extreme left under Manual I) and press one of the desired pistons.

Release both pistons. The selected registration is now memorised.

Press the General Cancel piston 'A' to turn off the tabs. Each time the reversible piston corresponding to the pro-

grammed preset is pressed, the stop tabs will NOT illuminate.

Select the desired registration by means of the stop tabs.

Press and HOLD the 'F' thumb piston (to the extreme left under Manual I) and press the piston marked '0' (situated

under Manual I) once. Release both pistons. The selected registration is now memorised.

Move the Crescendo pedal to the position you wish to programme (a number from 1 to 20 appears on the display).

Repeat operations 1, 2 and 3 for each Crescendo level required to be programmed.

Finally, press the General Cancel piston 'A' to switch off the tabs. Each time the Crescendo operates, the stop tabs

will NOT illuminate.
