+---- Thread: buzzing on door station (/thread-1867.html)
- wiredhome - 05-31-2010
i have a farfisa door station with dm02, i recently reworte the comfig file using default min responses, now there is a terrible buzzing on the intercom.
i have imported the new tuning parameters but it\'s still the same
anyone got any ideas?

Are you sure that wriiting a config file caused buzzing? Normally it is due to a loose connection of KA/KB or mic/voice or wires running too close to mains, not using twisted pairs etc
Try connecting the DM02 and speaker direct to Comfort using a shoirt cable Does buzzing still happen?

thanks chiu
the cable had drooped down in the panel and was lying on the transformer.
how can i improve the voice quality on the intercom speaker?
the client is using a dect cordless and a cellular phone when the system is away armed
regards
niall

Make sure the firmware is at latest version currently 5.183 see http://www.comfortforums.com/forum68/1866.html
Old versions < 5.145 intercom performance is not so good
Use the default tuning parameters in Comfigurator 3.1.9, Open new file and do a selective write to Comfort for Tuning parameters. It can make a world of difference
