The first image that you see in the front display is similar to:
The PLL (phase locked loop) enters in function and are necessary approximately
10-40 sec. (depends on the frequencies) because the oscillator locks on the
established frequency. The slowness of the operation is due to a slow answer of
the PLL filter that is designated in order to increase the stereo separation to the
lower audio frequencies.
6.1.4 Keyboards and indicators description and use
Are presents nine key on the front panel that control the transmitter.
