I have a m125 yea I know it old but I not able to make the alarm repeat in datebook. I've read the pdf file for the 100 seirs PDA's and it has it in there where you can set an alarm for reapeating. But in mine it doesn't look the same. I don't know if it my modle or an upgrade I have to do on the PDA OS cause my datebook version on my PDA is 4.0P and the OS PDA Desktop is 4.0.1 also when I check the datebook ver. on the Desktop it says 4.0.1. I don't know whats happening I just know I can't repeat my alarms when and important time comes up.
