I'm looking for a some assistance in fitting a new electric dimmer light switch. I'm in the UK if that makes a difference.

I am trying to replace my existing two-gang light switch with a LightWaveRF two gang dimmer but am not sure where to start as the instructions are telling me to look out for colored cables that aren't present in the existing switch.

Here's my original light switch setup:

The back of the switch

Here's the new LightWaveRF switch:

The back of the dimmer

What steps to I need to follow to install this switch?

Here's what's in the wall (just in case we need to use these!)

The rest of the wiring

In case your wondering the "S" terminals are for slave units
