OPERATING INSTRUCTIONS PM 5330
When changing the frequency via the knob, the key FREQ can be used to select the decimal
position that is to be changed. The symbols "►" and "o" are in front of the frequency field.
The decimal position selected flashes. This permits frequency ranges to run through either at
a fine or a coarse resolution (max. 1 MHz) .

Frequency and level may also be changed by operating the step keys "+O" "-O".
The input of the step width is prepared using the key (FREQ) ~ resp. (LEVEL) D. A flashing
triangle in the display indicates that the selected step width is being shown and not the current
output value.
Input is done via numeric keyboard, execution via the step keys. Pressing the step key several
times changes the value in single steps, holding the key pressed changes the value continu-
ously with increasing speed (max. approximately 10 steps a second) .
Example: Alteration of output level, step width 1 dB
