M3904 KBA Expansion Module Problem

[AugieDawgie]

I installed one of these on a 3904 phone this morning and it works great; however, the second one (which was working in test mode yesterday) is now continuously flashing the phone icon for all 22 buttons. I can't get it to stop...anyone have any ideas? Thanks

Hi,

I do not have any experience with M3900 KBA's, but did this is what I could think of:

Did you check the number of KBA's on the TN?
Is the connector connected correct (Not turned)? I think you can put it on only one way, just in case…
Is the firmware of the set ok? Is if older/newer than the test set?
What happens if you swap them? 1 to 2 and 2 to 1

Check your programing to see if you added 1 DBA for the add on module Unit and there are at least two types. Double check your Database. For 3900 series add ons it's "DBA", not "KBA".

Test the unit on known good phones and or a known good add on to the phone you are working on. If you listed KBA for the add on, that entry would be incorrect.


Good Luck

I use twenty-two button KBAs on my 3900 sets. The DBA have 8 keys with three "pages" for a total of 24 keys. KBAs can be programmed for M39044 sets. Are you using a display-based add-on or one with actual keys that need to be desied?

I'm using the KBA - actual keys, not display-based. It worked fine on my test phone, but when I went to plug it into another phone it started flashing, so I used another unit for that user and their's is working fine. I attached the first unit on my test phone and now it's flashing as well. Both of these units were new.
