System Vocabulary Version = 0 means the voice is lost
That means that there is no voice on the keypad.
You need to do a Vocabulary Upgrade to restore the voice.
See the topic at http://comfortforums.com/forum76/1623.html for instructions on how to do this
Hv tried that. Attempted to do Vocab upgrade,
Process stopped at "0%" followed by error code 6.
No Slave & Keypad was not attached during the process.
Hv tried restarted panel as well as restarted comfigurator.
These are new boards to be programmed before installation at site. Possibilities of lightning can be ruled out. Approx. 10 out of 160 boards hv this problem. Reluctant to send back to distributor cause very slow response. Other ways to try?
