The following is a description of the procedure for tuning the generator to a
colour receiver and for adjusting the "customer controls" of the colour
receiver to their proper settings. It is obvious that this procedure probably
cannot be completed if the receiver is defective.
— Make the connections as indicated in section "INSTALLATION", part C:
"Connections-RF", page 19.
— Connect the colour receiver to the mains.
Warning
In most IV-receivers equipped with valves, the heaters are series con-
nected; one pole of the mains is then connected direct to the chassis.
Therefore, before measuring on the receiver, connect it to the mains via a
separating transformer.
— Switch on the colour receiver.
— Switch on the generator (switch "POWER" to position "ON").
One of the channel scales will be illuminated, depending on whether aVHF-
or an UHF-button is depressed.
— Turn control "BURST AMPL." ully anti-clockwise (switch to position
"NOM", clicking sound!).
