I have a swift futura 4 bank. 2 front hatchriser
One rear for only 3 stops car 1 has 3 rear and 2
Are basement other 3 1-11. So quite a few times
Know I have had buttons at 11 not working and cars going to 9 opening and closing the doors buttons not working on 9 either. In the past it has been the button board
Two floors above where car is stopping .

Now it is moving 5th floor with 7. 11,7 and 2nd floor
Anyone come across this before? All the button board going bad or am I losing comms. Some point me in the right direction. I'm spun around in the trees. Thx for any feedback back. I'll be back to job in am. Thx again
