SMR4 Voice Card not updating or working correctly

5 out of 6 work perfectly. The last voice card displays green light only and seems to produce a drone note. Attempts to flash this card and update it are not working, although another card responded correctly. I have the 6 files to update the 6 cards loaded on the SD card. I have tried updating this card in several different slots on the mobo.

Send me back the chip.

I will do so.

Is this the correct address?

Yes

I mailed it today. Thanks for your help.
