Pd-4 RTC setting

Hi there People

Thanks alot for the advice on timecode and tc slates. etc. My shoot went
well . I used free run tc and this seemed to work well. I noticed that the
other guys on the job used tod at come points. I havent had my pd-4 for
that long and dont have the manual. I would like to check the real time
clock but I dont know how to view it or where ti set it up. I have looked
throught various pdfs but not been able to find it. Any help would be
excellent.
regards
dave
