OPERATING INSTRUCTIONS

MODEL 4200 (12 volt)

MODEL 4201 (6 voH)

THE CONTROLS for these receivers are shown in the illustration.

THE COMBINED VOLUME CONTROL AND ON/OFF SWITCH

is on the left of the five push-buttons. This control switches the receiver

on when turned clockwise and progressive rotation of the control increases

the volume. Turning the control fully anti-clockwise will switch off the

receiver. Allow about 40 seconds for the receiver to 'warm up' after

switching on.

THE TONE CONTROL is conoentric with the Volume Control and On/Off

Switch and provides selective tone oorrection for reproduction of either speech

or music. by four separate tone setting'>. The c011tr01is turned fully anti-

clockwise for speech and fully clockwise for music, the two intermediate

settings being provided to suit individual taste.

THE MANUAL TUN1NG CONTROL is on the right of the push-buttons

and provides completely variable station selection. A feature of this control

is that the knob will not engage the tuning mechanism until is is pressed in;

otherwise the knob will 'idle.' This prevents accidental disturbance of a

station-setting previously.selected by a push-button.

THE FIVE TUNING PUSH-BUTTONS provide automatic tuning of five

stations pre-selected from the Medium and Long wavebands. The right-hand

button provides for one station on the Long waveband, the four remaining

buttons beinz employed for Medium Wave pre-selection. The indication

"MW" (Medium Wave) or "LW" (Long Wave) is marked on the Tuning

Scale immediately above each push-button. Wave-change switching is auto-

matically effected when a button is pressed for any pre-selected station.

THE TUN1NG SCALE is divided into two sections, 'Medium Wave' and

'Long Wave,' and is calibrated in wavelengths. The tuning pointer has a

horizontal traverse and is viewed through a narrow window between the two

scale sections. Illumination of the Tuning Scale is by means of "edge-lighting."

SERVICE AREA OF B.B.C. STATIONS

{'~

At the present time the B.B.e. broadcasts three alternative programmes- the

'Home,' 'Light' and 'Third.' The wavelengths on which these programmes

are broadcast are shown in the table overleaf, while the map (also overleaf)

indicates the approximate geographical coverage of the various B.B.e. stations.

A glance at this map will show to which station the set should

tuned for

best reception in any particular area

the British Isles.
