Daitem D5131 v's D5131GB

[pgpg]

Good morning,

Just registered having stumbled across this site when looking for information re. handsets. 

I currently have a D5131GB handset with D5200 controller and although old tech it works ok.

I have been offered a D5131 handset by someone but wondered whether this would work given the GB suffix etc.

Have looked for information online to answer the question but nothing coming up on the differences between these two handsets.

If anyone here knows and can shed any light that would be great!

Thanks

Phil.
