06058M Slow Clock

My new 06058M has been in service for 2 days and the clock advances about 1 hour for about 3 hours of real time.  I have done the factory reset (i.e., accessing the main menu with the gear button, then using the up or down button to navigate to factory reset, and then following the on-screen prompts to perform the reset) multiple times with no success.  Also, the "auto cycle available screens" function runs very slow (e.g., when set to every 15 seconds the screens change slower than once a minute).   Is there a fix for these time-related problems?  Otherwise, how do I do a warranty return?
