E4440A "Frequency Reference Unlock" message

The following message is always displayed at the bottom of the E4440A screen " Frequency Reference Unlock". I carried out a quick test by transmitting a 1 GHz signal (-10 dBm) using an ESG and connected the output to the spectrum analyzer. I noticed that that peak is offset by around 40 kHz. I'd appreciate any feedback or solutions for my problem.
