Electric Ltd: Instructions: Television V470
These "Preliminary Operating Instructions" were for Ultra's first post-war television set. It stated "A more comprehensive instruction booklet is in the course of production and will made available shortly." Coupled with the fact that this set was contained in the 1947 Radiolympia brochure without a price leads me to believe that technical problems, or post-war shortages delayed the presence of this set. This document is referenced DX. 25727. For further information see the page Ultra V470.
Do not insert the mains plug into the power supply point until the following instructions have been carefully carried out.
The dealer from whom you purchased this television receiver will install it in your home, at the same time connecting the necessary aerial to the sockets provided, and setting the mains voltage adjustment to the voltage of your house electricity supply. [Fig.1 shows a voltage adjustment panel which can select 200-220, 220-240 or 240-260 volts].
If it can be arranged, the direct light from a window should not fall on the screen and where possible strong sunlight should be excluded from the room. The engineer will adjust the manual controls so that you will only have to carry out fine adjustments after switching on the set.
The controls in normal use are situated at the front of the receiver as shown in Fig.2.
On/off Switch and Brightness Control
This control enables the receiver to be switched on or off and varies the degree of brightness. To switch on turn the control to the right; if you continue turning this control in a clock-wise direction it will increase the brightness of the picture presented to suit your won taste and the lighting of the room. Do not have the brightness control higher than necessary as continued use at a very bright level will reduce the life of the viewing tube. To switch off, turn the control, fully to the left. Do not switch off the receiver by disconnecting it from the mains supply or by a wall switch as damage to the tube will result.
This control varies the sound volume level. To increase volume turn the control in a clock-wise direction.
|It may be necessary to occasionally adjust
the controls on the right hand side of the receiver.
Adjustment may be necessary to obtain a clear, crisp, picture, showing maximum detail.
This control varies the contrast between the light and dark parts of the picture shown on the screen, adjustment may be necessary to suit individual taste, and the general level of lighting in the room.
This control enables the picture received on the screen to be kept in horizontal synchronism with the picture transmitted; that is, if this control is incorrectly set, strips of the picture will slip sideways or resolve into a confused pattern of light and shade.
This control enables the picture received on the screen to be kept in vertical synchronism with the picture transmitted; that is, if this control is incorrectly set, strips of the picture will travel up or down the screen or a number of superimposed images may be seen.
These are situated at the back of the receiver and their adjustment should only be carried out by the television engineer.
The following adjustments should be carried out when the picture received is other than normal
