PROGRAM MODE

 

To enter the Program Mode hold down the “MODE/MIN” button for 3 seconds, until the time 
flashes in the top of the display.  The Program Mode Guide is laid out in a manner that allows 
you to program each function separately, or you can follow the instructions entirely to program 
the projection alarm.  Complete programming is usually done for the initial set-up, and will 
require you to skip step 1 and 2 of programming sections D and E.  To exit the setting mode 
simply wait approximately 10 seconds for the projection alarm to automatically return to normal 
operation.
