Hello,
I am facing the existing wiring of the LT 603N and I can't understand how it corresponds to the EXTEL UNY2 that I bought to replace it.
I have noted the diagrams of both devices and I would like to send them to you for help, but I don't know how to do that unless you give me your email address to send the diagram!
Thank you for your help.
Best regards.

Hello,
I don't know if this can help you, but by looking here:

We can see what each wire is for on the old one.
T1 Lock
1 Speech Out (Mic)
2 Speech In (Speaker)
3 Common
6 Call
So that would give us on the new one:
Old - color - new
T1 - dark blue - 5
1 - white - 1
2 - gray - 2
3 - yellow - 3 and 7
6 - light blue - 6
Basically, it's just T1 that becomes 5 and the ground to connect additionally to 7.
