If you're having issues with time and date synchronization see below:
By default RDS is turned on for each unit, this will sync the date and time to the radio from FM stations with a strong signal and who are broadcasting RDS time and date data. Sometime the broadcasting station could be issuing the incorrect time and date - this will then sync to your HomeHub Q. To resolve this you will need to disable RDS:
Once completed, to activate and Deactivate the Alarm Timer:
With the time correctly set, Press either ALARM 1 or ALARM 2 to activate or deactivate the timer.
Pressing once will display the alarms settings - time, volume, source etc. and pressing the alarm button again will enable or disable the alarm.
