Help changing bell 801 door entry handset to bell xl5

Hi

Trying to up grade my phone from a bell 801 to xl5. Not sure what I'm doing wrong as have reconnected the wires to the letters matching the 801 and nothing is working. Any help would be much appreciated

This was the 801 wiring

This was the lx5. There is a V and L which wasn't on the 801

Temrnals seems to match so not sure why nothing is working onnthe xl5.

Thanks
