changed DHW tank

[fysmd]

Hi I just had to change my v old water tank for a new 'un (leaked!) and I need to change from the contact DHW sensor to the insertion one which luckily I kept!

My silly question:

HOW ON EARTH DO I GET THE FRONT OFF THE BLOODY THING!
I need to remove the front of the CS92 so I can change the sensor - but how?

It looks like there is a "press here" slot on the bottom but I still can't get it free!

H E L P!

CS92A has two tabs underneath the batteries that you need to release to take the front fascia off (and its tricky to do at best!).
