Frequently asked questions
I tried out the sunrise but the light comes up really quickly – what's
wrong?
You probably didn't allow enough time for a full sunrise. For example, the
default sunrise takes 30 minutes so if the clock shows the time as 11:00 then
you need to set the wake-up time to at least 11:30.
What happens when I unplug my Zest or there's a power cut?
Your Zest keeps time for 30 minutes; other settings are permanent, so you
won't need to reprogram the unit, just plug it back in. If you need to adjust the
time, see Current time in Wake-up light options, page 13.
The display panel is too bright when I'm trying to sleep; how can I
change it?
See Display brightness in Wake-up light options, page 13.
How do I restore the default factory settings?
Turn off the power at the mains. Press and hold menu as you turn the power
back on. Release the button when the software version number is displayed.
One of the LEDs doesn't light up. Can I still use Zest?
It will make only a negligible difference to the light output if an LED has failed
and you can continue to use Zest.
LEDs have a very long lifetime compared to common light bulbs, 30,000 hours
being a typical figure. It's possible for individual LEDs to fail, in the same way
as other electronic components; however this is unlikely.
