What this means
The timer setting is invalid or the internal timer lost its correct time, commonly after a power interruption. The unit may still operate, but the timer schedule is unreliable.
What you can check yourself
- Check and correct the remote-control weekday and clock settings.
- Re-enter the required timer schedule.
- If the lamp continues blinking after the clock and timer are corrected, contact authorized service personnel.
