The Manual Tuning Control
provides completely variable station selection. A feature of
this control is that the knob will not engage the tuning mechanism until it is pressed
inwards; otherwise, the knob will "idle." This prevents accidental disturbance of a
station setting previously selected by a push button. The knob will remain in
engagement for manual tuning until released by pressing one of the push buttons.
The Tuning Push Buttons
provide automatic tuning of stations pre-selected from the
medium and long wave bands. The right-hand button provides for one station on the
long wave band and the remaining buttons to the left provide for medium wave
stations. The indicator "M.W." (medium wave) or "L.W." (long wave) is marked on
the tuning scale immediately above each button. Wave change switching is
automatically effected when a button is pressed for any preselected station.
The Tuning Scale
is divided into two sections — "medium wave" and "long wave", and is
calibrated in metres.
To Set Up the Tuning Push Buttons:
1. Select the wave band required by pressing the appropriate push button.
2. Tune in the desired station by means of the manual tuning control as
described above.
3. With the station accurately tuned in, remove one of the push buttons by
simply pulling outwards. A lip is provided on the underside of each button to
facilitate removal.
4. Insert edge of small coin in screw-slot of button plunger and unscrew (i.e. anti
clockwise) about half a turn.
5. Push the plunger as far as it will go, release and re-tighten by means of
screw-slot.
6. Replace the button. This push button is now set to the desired station and
independent of manual tuning. Proceed in the same manner for the remaining
buttons.
