It claims to "Auto Set", which makes you think of radio-controlled clocks that receive the time from a transmitter, but there's no mention of receiving signals in the feature-list or instructions. It has a battery back-up for the time, and a label says it should be plugged into the mains when the battery is changed. I think "Auto Set" just means that the time is maintained by a battery so that it's still there when you plug it in.
The time drifted off. It got to 10 minutes slow, and I couldn't find the instructions, and various experimentation with button pressing and button holding failed to find a time-setting mode, so I emailed John Lewis for advice.
They told me to "change the transmitter button on the back to the Western European or Central European setting" and it should reset itself. Hmmm. Tried it. Didn't. [Sigh] Looks like it has to go back to the shop.
Then I tried googling with the labels of all the buttons (just in case I hit on an instruction manual or a blog posting or something), and found this:
It's the instructions for a different clock, made by Acctim, but it has all the same buttons, and it has the same "Auto Set" feature. I wonder if Acctim manufacture the Indigo clock for John Lewis?
The instructions for the Acctim clock include advice for resetting the time if it's wrong. I can't find the Indigo clock instructions, but I did read them when we got it (yes, I know, only a Nerd reads the instructions), and I can't remember any mention of setting the time.
The same instructions don't work for the Indigo, but a slight variation does. So here, for the benefit of future googlers, are the instructions for setting the date and time on a John Lewis Indigo clock:
- Press the "-" button - the clock displays the year
- Press and hold the "ALARM SET" button for 5-7 seconds, until the year flickers briefly, then let go
- The year is now flashing - press "-" or "+" to adjust the year.
- Press "ALARM SET" and now the month is flashing. Press "-" or "+" to adjust the month.
- Repeat for date, hour and minute.
- Press "ALARM SET" one more time and the clock returns to normal operation, with new date and time set.
