Zodiac eXO iQ LS clock loss after powercut

[hERCOfLEXCO]

I have a Zodiac eXO iQ LS connected to iAqualink,, no problems there.
The problem I am having is that we get the occasional power cut and every time this happens the unit's clock needs to be reset.
I manage the pool but travel a lot for work so this is a big issue as soon as the hour is lost the schedule looses relevance and can often mean to chlorination until I return.
Is anyone aware if the unit has an internal battery that may be dead? Does anyone have a wiring diagram for this unit.

First post here, let's see how it goes

Here appears to be the manual. Page 54: "Data loss (time, etc.) | Contact your retailer to replace the 3v CR 1220 battery."

If you're handy, I'm sure you can do it yourself. Google is your friend when you own a pool.

Update: I took the screws out of the bottom section of the chlorinator, I can see a coin cell battery holder!!! Looks like it might be tricky to get the coin cell out with the top half of the casing on though.

Instead of creating a new thread, necroing this one, google unfortunately isn't my thread as I couldn't find any info about battery replacement.

Has anyone cracked this device open and replaced the batteries. As above the manual says CR 1220, hopefully this is just one button battery...how do I get at it?

As an aside I also have a Tri and that had three soldered tabbed Varta V40H on the display PCB which was a real pain.

Thanks!
