The radio controls are as shown below:

first switch position turns the radio on with the dial illumination on. The second
position turns off the illumination.
3.2

Turn fully anti-clockwise to reduce the volume and clockwise to increase.

Tuning
This is decorative only and moves the tuning dial indicator.
3.4

This control has no function.
3.5
VU Meter
The original unit had a ‘magic-eye’ tuning level indicator. The radio does not have a
tuning function, or the high voltages necessary to drive a ‘magic-eye’ valve so this
has been replaced with a miniature VU meter which indicates audio signal level.
