Mains voltage - Fuses

Check that the receiver is set to the correct mains voltage -- see figure on page 7.

230 volts, 50 Hz:

The receiver is set to 230 V +/- 10%, 50 Hz, at the factory and fitted with a 200 mA mains fuse for this voltage.

115 volts, 60 Hz

• Set the mains voltage selector for 115 V (use a screwdriver).
• Remove the 200 mA fuse and insert a 400 mA fuse. Open the fuse holder with a screwdriver or a coin.

Fuses:
230 V, 50 Hz: 200 mA, slow-blow, 5 x 20 mm.
115 V, 60 Hz: 400 mA, slow-blow, 5 x 20 mm.

Connections:
The illustration on page 15 shows alternative connections for the mains supply.

Connections

(A) Antenna 75 ohm:
FM antenna with 75 ohms down lead should be connected direct to this input.

FM antenna with 300 ohms down lead should be connected via an antenna transformer 300/75 ohms. A 75 ohms antenna plug with an antenna transformer will be supplied with receivers intended for the US market.

(B) Variable Output:
For connecting to a control amplifier/amplifier. Output voltage 0 to 1.5 V/470 ohms.

Layout for connections, see pages 14 and 15.

Output Level

The signal level from the Variable Output can be controlled by means of the Output Level control. The level can be adjusted to suit the input requirements of the following amplifiers.

---

De-emphasis

The selecter marked De-emphasis at the back of the receiver has three positions:

25 microseconds:	For receiving Dolbyized* FM programs.
50 microseconds:	For receiving FM transmissions with 50 microseconds pre-emphasis (European standard).
75 microseconds:	For receiving FM transmissions with 75 microseconds pre-emphasis (US standard).

*	"Dolby" and the double-D-symbol are trademarks of Dolby Laboratories Licensing Corporation.

---

Mains switch

• Check that the receiver is set to the correct mains voltage (see instructions at back of receiver) and that the correct fuse is fitted.
• Plug in the mains plug.
• Press in the mains button marked Power.
• When switched on the receiver goes over to manual station tuning, F .

---

Manual station tuning

If the Servo AFC circuit is connected, it will be automatically disconnected when you manually tune in to a station. This provides more accurate tuning. The display will show F .

Adjust the tuning knob (7) until you find the required station.

• Frequency: Read the main scale (6).
• Signal strength: Read the signal meter (3). The meter displays signal strength in microvolts.
• Centre-tuning: The Tuning/Frequency meter (4) shows deviation from the centre position when the f indicator (5) lights up. Tune in until the pointer is in the centre.

When you release the Tuning knob, the Servo AFC circuit will be automatically connected again after 1 to 2 seconds.

Storing station data

It is assumed that this is the first station data to be stored, and that the station data can be stored in any program memory.

Tuning in the station

• Tune in the station (centre-tune) as described under Manual station tuning, see above.

Storing

• Press in one of the Program Preset buttons (1), e.g. No. 8.
• The display (2) will change from F to 8.
• Press the Store Program button (10).
• The display will now show P with a blinking dot which indicates that the receiver is in the programming mode. You will all the time listen to the tuned in station.
• The display will change from P to 8 and the Tuning/Frequency meter (4) will show the frequency of the station. The station is now stored in Program Preset 8 and can be recalled later whenever the Program Preset 8 button is pressed.

The same procedure should be used to store station data in Program Preset memories 1 to 7.

The operating procedure is the same, whether a program selector is vacant or you want to change the station data already stored.

---

Storage unit (Memory)

The electronic memory can store data on 8 pre-tuned FM stations for rapid selection later. The memory is powered by an internal battery so that the stored data is not lost when the receiver is switched off.

The battery is the NiCd type which is charged continuously when the receiver is switched on. If the receiver has been switched off for a long time e.g. 1/2 year to 1 year, the battery could be discharged so that the data stored in the memory is lost. In this event, the programming must be done again. Also after this kind of interval, the receiver must be left switched on for a period to allow the battery time to charge.

Under normal conditions the battery will have a life of 10 years. The battery should be changed by a qualified serviceman.

---

FM-Stereo/Mono

The MPX indicator will light up when the receiver receives a program with a pilot tone from an FM stereo transmitter. If the stereo program is affected by noise, you can press in the Mono button. Then the stereo program will be reproduced in mono with less noise. The MPX indicator will continue to be on to indicate that the receiver is receiving a stereo program.

At low signal strength the receiver will automatically switch over from stereo to mono.

---

Servo (Automatic Frequency Control)

The Servo circuit ensures the automatic precision centre-tuning of a manually tuned station.

• Press the Servo button to bring in the Servo circuit. The light will come on.
• When you are tuning in a weak station which lies close to a strong station on the scale, it can be an advantage to disconnect the Servo to prevent the Servo from automatically locking itself on to the stronger of the two stations.

During manual tuning the Servo will be disconnected as soon as you touch the Tuning knob. Re-connection of the Servo circuit is automatic within 1 to 2 seconds after you release the knob.

---

Muting

The muting circuit blocks weak signals and thereby ensures noise-free manual tuning.

• Press the Muting button to bring in the muting circuit. The indicator light will come on.
• To tune in a weak station, first release the Muting button to cancel the effect of the muting circuit. Otherwise the weak stations will not rise above the muting threshold.

Mounting the side panels (extra)

NOTE!

When fitting extra side panels you must use the long screws (A) which are supplied.

Take care of the short screws (B) originally used to hold the side panels because you will need them if you remove the extra side panels. The long screws must not be used without the extra side panels because they will cause damage inside the receiver.
