Landis & Gyr rwb200 Battery replacement

[DonnyDIY]

Hiya. I'm a newbie here so go easy on me please .

I have a Landis & Gyr rwb200 programmable timer. However when the power goes off all the clock settings revert to 12:00. So I suspect the internal battery has gone?

Is it replaceable and, if so, how do you access it please? I have no idea how to get the front off without wrecking it!

Thanks very much.

It's on what's know as a common back plate 2 screws underneath
Loosen them then lift bottom edge.
Replacement battery readily available do a search on Ebay.
