K8060 trimmer

Hi. While assembling a K8060 kit I noticed a contradictory information in the illustrated assembly manual.
On the page 6 of the manual the value ov the RV1 rimmer is reported to be 1Kohm.
In the schematic on page 19 the value is 500ohm.
The question is: Which is the correct value for RV1?

Thanks in advance.
Michele

Supplied part is correct.
