COMPRESSOR (1910 JTD)
The compressor fitted on this version is the SANDEN SD7V16 variable capacity type.
The capacity of the compressor varies starting from the maximum value (161.3 cm^/rev) and is gradually
reduced (up to 10.4 cm^/rev) according to the system load variations. - changed outside temperature
and/or humidity conditions or sharp variations in the engine load.
This solution is defined as "unlimited variable capacity".
The compressor is the alternating piston type: the variation in capacity is achieved by tilting the connect­
ing rod holder plate with a consequent variation of the piston stroke: the movement of the plate is acti­
vated by an internal regulation valve according to the balance of pressure upstream and downstream of
the compressor. In particular, a low intake pressure involves the shuttering of the compressor (reduced ca­
pacity), whilst a high pressure involves operation at maximum power (maximum capacity).

Operation
The SD7V16 compressor is illustrated in the diagram; it consists of seven pistons (2) and connecting rods
(3) fastened to a connecting rod holder plate (4). The rotary motion of the plate (4), on the shaft (5)
produces the alternating movement of the pistons.
A change in the plate angle allows an alteration in capacity: maximum inclination (as in the diagram) for
maximum capacity; almost zero inclination (vertical position) for minimum capacity (virtually nil).
The plate (4) rotates around the pin (6) hinged on the shaft (5) arm (7).
The movement of the plate (4) in relation to the shaft (5) takes place by means of splining made from a
low resistance material.
The plate (4) slides below along a guide (9) via a runner (8) made from a low friction material.
The diaphragm valve (1) controls the flow rate adjustment according to the difference between Pa (intake
pressure) and Pi (pressure inside the compressor).
N.B. the solution adopted for this compressor is designed to keep the internal pressure Pi constant, with
advantages in terms of ease of adjustment and quiet, smooth operation.

Deactivating AF function
NOTE: tihs function can be deactivated only when receiving stations with alternative frequencies.
To deactivate the AF, simply give the AF key a short press. When a short message 0FF>;
will appear on the display.
Do the same to reactivate.
NOTE: the AF OFF reception condition should be considered a local, temporary solution because it in­
volves manual compensation of a broadcasting service.
For this reason, tuning will automatically be switched to AF ON upon each manual or automatic tuning
control or selection of another stored station.
The AF OFF condition can be stored, together with the station, when it is activated before storage.
If an attempt is made to deactivate AF for a station that is not broadcasting using an RDS protocol, the
message "NO AF" will appear on the display.
RDS OFF
With some stations (e.g. MF103.3-ISORADIO in Italy), it is advisable t store the station in RDS OFF
mode to receive optimum reception.
To activate RDS OFF mode, simply press the AF key for more than 2 seconds.
RDS OFF mode, as with AF OFF mode, is absolutely temporary. The RDS OFF condition can be stored,
together with the station, whenever it is activated before storage.
Storing RDS stations/programmes
Press the selection key for stations 1 to 6 for more than 2 seconds until the station can be heard
again.
NOTE: theAF ON I OFF and RDS ON I OFF modes are stored together with the station.

TUNING
Tuning RDS stations/programmes with automatic search for stations
1. Use the BN key to select the range: FM1, FM2, FM3, MW or LW.
The automatic search within FM ranges operates with two degrees of sensitivity. During the first search
through the reception range, the search is carried out for stations with high field intensity (local sta­
tions). The second search seeks stations with low field intensity (distant reception). The message "DX"
appears on the display during the search.
The DX function may be deactivated (see chapter on EXPERT control level)
2. An automatic search in the required direction may be started by giving a short press to one of the keys
A or B. The display shows the relevant frequency: when a station with an identification code is found,
this is shown on the display. Otherwise the frequency indication remains.
If the RDS station/programme tunes within the selected range, it is stored on a selection key for sta­
tions 1 to 6. The relevant number appears on the display, e.g. "3" for memory position 3.
3. If the tuned station is to be stored on a selection key, proceed as described in the paragraph on station
selection keys.
Recalling stored RDS station/programme
Use the BN key to select the range: FM1, FM2, FM3, MW or LW.
Give a short press to the selection key for stations 1 to 6.
Even if the radio power supply is disconnected, the memory contents of the station selection keys are
maintained.
Manual frequency tuning
1. Use key BN to select the range:: FM1, FM2, FM3, MW or LW.
2. Pres one of the keys A or B for 2 seconds until "MAN" appears on the display and the frequency tun­
ing is not visible. Continual switching takes place during fast forward when one of the keys is held
down.
3. Use keys A or B to tune in the required direction: the frequency will be increased or reduced by 50 Hz
while in FM or 1 kHz in AM.
4. If the tuned station is to be stored on one of the station selection keys, proceed as described in the
paragraph on "Station selection keys".
5. Conclusion of manual frequency tuning: give a short press to one of the station selection keys from 1
to 6.
NOTE: If no key is pressed for 60 seconds, manual frequency tuning is automatically concluded.
Automatic station storage: AUTOSTORE
Automatically store the most powerful stations in the selected local reception range on station keys 1 to 6.
Range selection: FM I, FM 2, FM 3, MW or LW.
Press the BN key for more than 2 seconds until the message "AS" appears on the display and the fre­
quency indication changes.
The station with the best reception can be heard at the end of the search.

Tuning RDS programmes (IS LEARN) function (see EXP)
The IS LEARN function (which can be run only after activating the EXPERT function) can be used to
store up to 30 programmes in the IS memory (virtual memory area that does not correspond to storage
keys).
Stored programmes can be called up one by one as described in the EXP section.
The IS memory is useful when the station selection keys are restored or when the tuning stops on a new
reception field and you do not wish to deleted stored stations from preset keys.
Starting the automatic IS LEARN function
Use the BN key to select the range «FM 1», «FM 2» or «FM 3».
Press the SRC key for longer than 2 seconds. «IS ...» will appear on the display, the receiver starts the
search.
If an attempt is made to start the IS LEARN search without the IS mode being active (see EXPERT), the
display will show the message "EXPERT".
NOTE: Always wait for the end of the automatic intelligent search (IS).
If no reception is possible, the automatic intelligent research may stay on, e.g. in an underground garage
or if the aerial is defective. In this case, the automatic search can be interrupted by pressing one of the
station selection keys from 1 to 6.
The automatic intelligent search IS ensures up to 30 stations can be stored with optimum reception.
During automatic intelligent search IS, RDS programmes are stored first ordered by programme code, fol­
lowed by FM stations.
Calling up the contents of the IS memory
Stations can be called up from the memory in the required direction by giving a short press to one of the
keys A or B. «IS-SCAN» appears on the display during station selection.
Programme types (PTY)
Many radio programmes offer the programme type service (PTY) in the FM range (FM1, FM 2, FM3) The
message «NEWS» is displayed during a news programme, for example.
The PTY function activates a search filter that allows the radio to tune only to stations that broadcast pro­
grammes with a preset PTY code.

The types of programme offered by a radio station vary according to the type of programme transmitted.
