I am using a T41 phone and trying to connect a expansion module to it. I have a few questions since the device is only lighting up but not showing on the DSS Key screen.
1. Should I see the EXT Key option on the DSS KEy screen?
2. Is there an expansion Module that will work with a a T41?
The phone right now is on Firmware Version 36.73.0.50 and Hardware Version 36.0.0.0.0.0.0

Hi Sir，

The T41P don't support connect the expansion module so that you can't see the EXT key option in the DSS Key screen.

Best Regards.
